color

The GIA Color Scale extends from D (colorless) to Z (light yellow or brown). Although many people think of gem quality diamonds as colorless, truly colorless diamonds are actually very rare. Most diamonds used in jewelry are nearly colorless with tints of yellow or brown.

The color evaluation of most gem-quality diamonds is based on the absence of color. A chemically pure and structurally perfect diamond has no hue, like a drop of pure water, and consequently, a higher value. GIA's D-to-Z color-grading system measures the degree of colorlessness by comparing a stone under controlled lighting and precise viewing conditions to masterstones of established color value.

Color grades are determined by comparing each diamond to a master set. Each letter grade represents a range of color and is a measure of how noticeable a color is. Fluorescence Some diamonds can emit a visible light when exposed to ultraviolet radiation, but fluorescence is not a factor in determining color or clarity grades. However, a description of its strength and color is provided on GIA Reports as an additional identifying characteristic.

clarity

clarity1

Clarity is most often mistaken as being the factor that determines a diamond’s sparkle and brilliance. This is not true. Clarity describes the presence of imperfections both on and within a diamond. Most imperfections are microscopic flaws, or “inclusions,” formed inside the diamond during the formation process known as crystallization. Other flaws, however, appear on the surface of a diamond and may have appeared during the cutting process.

Essentially, the clarity grade describes the flawlessness of a diamond; the fewer the imperfections, the higher the clarity grading. Naturally, these imperfections have an impact on the value of a diamond, particularly those that may be viewed by the naked eye. In order to find and plot a stone’s flaws, gemologists use at least 10x loupe magnification when grading for clarity. Clarity grades range from Flawless, which are diamonds that reveal no imperfection even under 10x magnification, to Imperfect 3, which are stones with distinct blemishes visible to the naked eye. See the chart below for a description of each clarity grading.

clarity3-1 clarity3-2 clarity3-3 clarity3-4

The GIA Clarity Scale includes eleven clarity grades ranging from Flawless to I3. Because diamonds form under tremendous heat and pressure, it is extremely rare to find a diamond that lacks any internal and external characteristics. These characteristics are a by-product of its formation and help gemologists separate natural diamonds from synthetics and simulants, and identify individual stones.

cut

cut1

Of the four Cs, cut is perhaps the most important factor affecting a diamond’s overall quality and beauty. A diamond’s brightness, or its brilliance, is determined by how much light is reflected back to your eyes. Light enters the stone through the crown, which is the portion of the diamond above the girdle. The crown is made up of the table, which is the large flat facet on top of the diamond, and many crown facets. It then travels to the pavilion, or body, of the stone, where it is reflected from one side to the other and then back through the top and to an observer’s eye.

A well cut, well proportioned stone evenly reflects and refracts light within the stone, thereby producing an eye-catching, fiery spectrum of color. A poorly cut diamond, on the other hand, allows more light to pass through or “leak” from the sides of the stone, which results in a lifeless appearance with reduced sparkle.

cut3-1 cut3-2

The science behind diamond cutting is more or less an exercise in proportion. Changing the proportion of a diamond’s depth and width is done in order to maximize the stone’s brilliance. If the cut adheres to certain “ideal” proportions, the results can be spectacular. If poorly cut, the results can be so bad as to cause structural instability, which makes the stone susceptible to breaking. Because cut is so important, gemologists have developed grading methods to assist consumers in determining a diamond’s cut. In general, they are: Ideal, Excellent, Very Good, Good and Fair.

The ideal proportions shown below are known as the Tolkowsky Theoretical Brilliant cut. In 1919, Marcel Tolkowsky published a paper detailing ideal proportions for a round brilliant diamond. Modern cutters offer a wide range of opinions on the “ideal” cut, but Tolkowsky’s findings are mathematically indisputable and remain the basis for these modern ideal proportions.

cut4

The GIA Cut Scale ranges from Excellent to Poor. A polished diamond’s beauty lies in its complex relationship with light. The magnificent display you see is made up of three attributes: Brightness is the combination of all white light reflecting from the surface and interior of a diamond. Fire describes the “flares” of color emitted from a diamond. Scintillation describes the pattern of light and dark areas and the sparkle you see when the diamond, the light, or the observer moves. A diamond’s proportions affect its light performance, which in turn affects its beauty and overall appeal. Diamonds with fine proportions, symmetry, and polish optimize their interaction with light, and have increased brightness, fire, and scintillation. GIA assesses these factors for standard round brilliant diamonds in the D-to-Z color range.

carat weight

carat1

A carat is a unit of measure for diamonds, where one carat equals 100 points, or 0.2 grams. This measurement is referred to as the carat weight and is used to determine a diamond’s size. Larger diamonds are more rare and therefore more highly valued. In addition, larger diamonds make it easier to see the effects of other key characteristics, such as cut and color. Depending on the significance of these other characteristics, diamonds of a similar size (carat weight) may differ dramatically in price.

carat2

Diamond carat weight is the measurement of how much a diamond weighs. A metric "carat" is defined as 200 milligrams.

Each carat can be subdivided into 100 'points.' This allows very precise measurements to the hundredth decimal place. A jeweler may describe the weight of a diamond below one carat by its 'points' alone. For instance, the jeweler may refer to a diamond that weighs 0.25 carats as a 'twenty-five pointer.' Diamond weights greater than one carat are expressed in carats and decimals. A 1.08 carat stone would be described as 'one point oh eight carats.'

All else being equal, diamond price increases with carat weight, because larger diamonds are more rare and more desirable. But two diamonds of equal carat weight can have very different values (and prices) depending on three other factors within the 4Cs: Clarity, Color, and Cut. It's important to remember that a diamond's value is determined using all of the 4Cs, not just carat weight.

How did the carat system start?
The modern carat system started with the carob seed. Early gem traders used the small, uniform seeds as counterweights in their balance scales. The carat is the same gram weight in every corner of the world.

What are "magic sizes"?
Some weights are considered "magic sizes" — half carat, three-quarter carat, and carat. Visually, there's little difference between a 0.99 carat diamond and one that weighs a full carat. But the price differences between the two can be significant.

One carat equals 200 milligrams in weight. For diamonds under one carat, each carat is divided into 100 points – similar to pennies in a dollar. 0.75 ct. = 75 points, 1/2 ct. = 50 points.

How to Measure Your Own Ring Size

sizing1
To measure your ring size, all you need is the following:
  • A 6-inch strip of paper. (Since the ring must fit over the joint, it is more convenient to measure your finger with a strip of paper. This way, you can check whether the paper goes around your finger)
  • A pen to mark the paper
  • A ruler
sizing2
  1. 1.       Wrap the piece of paper around the base of the finger that you want to measure.
  2. 2.       With your pen, mark the paper where it overlaps to form a complete circle around your finger.
  3. 3.       Use your ruler to measure in mm the length of the paper – from the end until where you marked it.
  4. 4 .      Compare this measurement with the chart below to find out what your ring size is.

All You Need to Know about Gold Metal

Purity of Gold

As you may already know, gold has been used in jewelry since ancient times. This age-old reliance on gold in jewelry manufacturing is confirmed by artifacts that have been recovered today during excavations of ancient burial mounds and pyramids. For centuries, gold has been noticed and preferred for many reasons, including its attractive appearance. However, back in the old days, the concept of mixing metallic elements to create a stronger metal, called an alloy, did not yet exist . This meant that all jewelry back then was made from or with pure gold. Today, we know that pure gold is too soft for everyday wear, so it is combined with a mixture of metals like silver, copper, nickel, and zinc to give it strength and durability. Pure gold is called 24K (karat) gold or marked as "999.9."

gold1

Stamps of karats are relatively recent. Gold jewelers have started to use terms such as “375/9K,” “585/14k” or “750/18K” to refer to the respective base alloy of gold and other precious metals. For example:
"18k" = "750" gold is composed of 75% pure gold and 25% accurate alloys.
"14k" = "585" gold is composed of 58.5% pure gold and the rest are accurate alloys.

The ratio between the gold content system
gold2

Accordingly, the higher karat number of gold, the better quality and expensive the product.

Colors of Gold

Gold in its pure form is not sufficiently solid. Therefore, pure gold cannot be used in the manufacturing of jewelry worn on a daily basis. This is why the production of gold jewelry includes impurities of other metals. This mixing of metallic elements makes the resultant alloy metal harder and gives it different color casts. Gold jewelry can come in completely different colors: yellow, white, pink, green and even black. The color depends on the metals that compose the alloy ligature.

gold3 Yellow Gold

Yellow gold is an alloy metal with the addition of silver and copper (approximately equal amounts). This alloy is the original color of pure gold.

Rose Gold

Rose gold comprises 75% pure gold and 25% alloy, which is also painted in copper but with the addition of silver. The color’s comparison to delicate rose flowers has made it a favorite material of many fashion houses of today.

White Gold

White gold is prepared by adding nickel, palladium or platinum. This alloy is brighter and more brilliant than the original pure gold. White gold has firmly established itself as a favorite in the fashion and design worlds and is an integral part of today’s diamond jewelry. In fact, jewelry that is made of white gold is a status symbol among owners. Outwardly, this material is very similar to platinum, but its price is almost two times lower.

Red Gold

Red gold comprises 75% gold and 25% copper mixture, resulting in a gorgeously warm and rich metal.

Green Gold

Green Gold is achieved by adding silver. The secret of this alloy metal is that it is fragile; the higher its silver content, the greater the risk of deformation. The rich green or pale green hues in this gold is worth its vulnerabilities. Green gold is typically used as a part of a jewelry piece or gold product for decorative purposes.

Black Gold

Black gold is a recent invention. It is rather complicated to get black gold. Manufacturers do this by adding a piece of jewelry plated with black rhodium or ruthenium. This allows a range of colors from gray to black. Another method to achieve black gold is to use amorphous carbon, which is particularly applicable in the production of gold hours. Black gold is also created by adding to the alloy metal cobalt and chromium in respective proportions of 15% and 10% and by oxidizing the surface with t = 700-950°C. This type of gold is used in jewelry, helping jewelers and designers reveal new facets of their art.

Tips for Buying Tennis Bracelets

gold1 Have you always wanted to show off an elegant tennis bracelet? There are a few things to consider before urchasing one. Here are some tips to help you shop:
  • The most essential and important aspect to look for in a tennis bracelet is its diamonds. Be sure that the bracelet you choose contains carefully selected good-quality diamonds. Since tennis bracelets do not come with diamond certificates, check as best you can the precision of the diamonds’ cut and polish. Use your personal judgement regarding the overall look of the bracelet’s stones. As WELAMOND specializes in the manufacturing and trading of diamonds of all sizes, we are able to create an impressive selection of jewelry pieces that contain the best diamonds at the most competitive prices!
  • The type and color of bracelet metal should match your other jewelry and even that of your partner’s. If you are a man who wishes to surprise your partner with a tennis bracelet, it’s advisable to check out the predominant color of all her other jewelry. For example, if most of her pieces are yellow gold, it is preferable to buy a yellow-gold tennis bracelet.
  • The quality of the tennis bracelet is essential. The bracelet’s links must be tight yet flexible enough to withstand pressure. Otherwise it will break or tear.
  • Be sure that the diamonds are set flawlessly.
  • Pay attention to the diamond tennis bracelet’s clasp. This fastener should be the main emphasis at time of purchase. Since the bracelet’s clasp is opened and closed frequently, it is advisable that it will contain a security mechanism ensuring that the bracelet will not open accidentally.

It is important to check the return policy. This is especially true if the tennis bracelet is being purchased as a gift. Lean more here about the WELAMOND return policy.

It is advisable to buy the tennis bracelet in a place that controls the quality of its products, like WELAMOND experts do.

Consider the tennis bracelet’s length. Suitable tennis bracelets should not be tight on the wrist but also not too loose. The best test is to put a finger between your wrist and the bracelet. If the margin is significantly larger or smaller than your finger, the tennis bracelet is not suitable. The standard length for a tennis bracelet is 18cm.
Looking for a classic tennis bracelet designed with diamonds? You came to the right place! At the world-leading jewelry brand WELAMOND website, you will find an extensive collection of tennis bracelets that are inlaid with top-quality diamonds. Our selection of designs ranges from classic and luxurious to contemporary and cool.

Why Are Tennis Bracelets Called ‘Tennis Bracelets’?

While admiring the elegant beauty of a tennis bracelet, have you ever wondered how it got its name? Here, we’ll try to explain the origin of the name “tennis bracelet.”
A tennis bracelet is a bracelet made of gold, platinum or silver and embedded with dozens of identical-looking diamonds along its entire length. The way the diamonds are finely set in a tennis bracelet forms an elegant, flexible chain of shimmering brilliance. The diamonds’ uniformity projects a sense of delicacy that is hard to replicate in any other jewelry piece. Therefore, the most beautiful tennis bracelets contain diamonds that match in size, color, clarity and polish. The larger the diamonds, the higher the quality of cutting and polishing they require. Otherwise their brilliance will be affected as well as that of the bracelet’s overall appearance.
Despite its name, the tennis bracelet actually has no connection to the sport. Research shows that the moniker came to this bangle bracelet at random. It can be recalled that during a professional tennis match in 1987, tennis pro Chris Evert interrupted her own match to look for the diamond bracelet that fell off her wrist. However, while this anecdote would make for a good explanation, it is not how the tennis bracelet got its name.
There seems to be no historical connection between the sport and this bangle’s name. Over time, though, the tennis bracelet has become associated with tennis, given the dignified, distinguished image of both. No other piece of diamond jewelry is as flexible, adding beauty and elegance to the tennis players’ swift arm movements on the court. What better way to enhance a game of tennis or any other activity than by wearing a diamond-embedded tennis bracelet that radiates grace and agility?
Despite no explanation of its name origin, the beloved tennis bracelet is a great example of how a nickname can complement a piece of jewelry. Its name conjures up images of the prestige and refinement related to tennis. The rest of the bracelet’s appeal comes from its luminous, eye-catching diamonds
Looking for a classic bracelet that is designed with high-quality diamonds? If so, you have come to the right place. At WELAMOND, the world-leading jewelry brand, you will find an extensive collection of bracelets inlaid with diamonds. The website offers selections of jewelry that include classic, luxury, contemporary and trendy designs.

How to Choose the Best Engagement Ring

How to Choose the Best Engagement Ring

You have the perfect partner. Now you need the perfect engagement ring for her. As there are many factors to consider when choosing a diamond engagement ring, the buying experience can be overwhelming. To help keep the pressure low and excitement high, here are some tips to keep in mind when looking for that all-important symbol of your love and commitment:

Tips for Choosing the Best Engagement Ring
Start with the band.

When choosing an engagement ring, it's best to start with the band. This is the part of the ring that goes around her finger. Typically, bands are made from gold, silver, platinum or a combination of metals. It’s best to know what your future fiance’s jewelry preferences and tastes are since gold comes in a variety of colors such as white, yellow and rose. Each of the metals has its advantages and disadvantages in terms of ring durability and price.

best1 Select the diamond.

After selecting a suitable band, you can move on to the highlight of all engagement rings: the diamond. The key to choosing a diamond is incorporating the 4C’s into your purchasing decision. These are cut, color, clarity, and carat weight, which all impact diamond cost and quality.

CUT

A diamond’s cut refers to its proportions and angles, not to its shape. A well-cut diamond reflects light from one facet to another and projects the light through the top of the stone, maximizing its sparkle. If diamond is not cut well it will have a dull appearance, which will overshadow the other C’s.

best2
COLOR

Diamonds come in a variety of colors and hues, including pink, yellow, red, brown, among others. A diamond’s color grade ranges from D (colorlSess), the most expensive, to Z (light yellow).

best3
CLARITY

The fewer imperfections, or inclusions, a diamond has, the more clear – and pricey – it is. Clarity is also measured on a scale.

best4
CARAT WEIGHT

A diamond’s weight is measured in carats. The heavier the diamond, the more expensive it is. Depending upon how the diamond is mounted, a professional jeweler can make a diamond appear larger than its carat weight suggests.

Know Her Favorite Shape.

Chances are, your future fiancé has a preferred diamond shape. To avoid disappointment, find out what it is. The main diamond shapes are Round, Princess, Emerald, Asscher, Cushion, Marquis, Radiant, Oval, Pear, and Heart.

best5
Choose the Setting.

A ring’s setting is what holds the diamond in place. Your girlfriend’s tastes will also help you determine the ring setting. Some rings have a pronged or open-invisible setting that focus attention onto the diamond. Other settings, including the bezel and half-bezel settings, fully or partially surround the diamond. There are also pave and channel settings, which mount a number of stones next to each other.
Types of settings depend on the diamond itself as well as the metal and artistic and functional features of the jewelry piece. Consumer preference and demand are additional factors taken into account when deciding upon which diamond setting to use. While most diamond settings were created long ago, there are also contemporary methods used to set precious stones into jewelry that improvise on the classic, age-old techniques.

The Prong Setting best6

The prong setting, the most popular diamond setting, uses the help of “legs,” or prongs, to keep the diamond embedded in the jewelry piece. The prongs are specially designed to focus all attention onto the stone. In this setting, the stone’s every detail is on full display. The prong setting opens the diamond to the world, allowing light to pass through it from all sides, thus enabling the diamond to shine from all angles.

While the classical prong setting features four prongs, six prongs can also be used to create the impression that the diamond is larger than it actually is. There is also diamond jewelry that features a three- or eight-pronged setting. Jewelers can show off their creativity with a variety of prong shapes and sizes.

The Shared Prong best7

The "shared prong" setting is related to the prong setting. Here, one prong is used to strengthen two adjacent diamonds. This placement is very elegant but requires the use of diamonds that are the same in color, clarity and sizes.

The Pave Setting best8

Similar to the prong setting, the diamond pave setting is used to densely embed a large number of small diamonds next to one another to form a single shiny surface. This setting gives the diamond jewelry piece the appearance of featuring a carpet of diamonds. To professionally mount diamonds in a pave setting, a microscope is needed. All of the tiny-sized diamonds are held in place by minute, almost invisible “teeth” or prongs. The pave setting is a complex technique most beautifully achieved in the hands of a talented, skilled jeweler.

    The following are some tips from a WELAMOND expert about how to recognize a high-quality diamond pave setting:
  • Look for unity of color in all of the set diamonds
  • Look for maximum density of set diamonds but with a minimum lumen through which visible gold
  • Be sure there is an equal amount of spatter holding the diamonds in place
The Bezel Setting best9

The bezel setting is one in which a diamond is held in place by a metal mandrel, or frame, surrounding it from all sides. This is the most reliable and secure way to set a diamond into jewelry. However, the frame this setting creates around the diamond tends to affect the perception of diamond color and size. Since fewer angles of the diamond are exposed in the bezel setting, the diamond receives less light than it would in a more open prong setting. Less light means less sparkle and shine. However, a gold frame surrounding the diamond in a bezel setting can make the stone appear bigger than it is.

The Half-Bezel Setting best10

The half-bezel setting is used to maximize the amount of light shining onto a diamond that is set in a ring. In this setting, instead of fully surrounding the diamond, the ring’s metal frame is divided into two, hugging the diamond on opposite sides. In comparison to the bezel setting, the half-bezel setting opens up the diamond to more light, allowing it to enter the diamond on top and from two sides. Able to reflect more light, the diamond in the half-bezel setting sparkles more compared to one in a full bezel setting.

The Channel Setting best11

The channel setting is used for mounting a number of small diamonds next to each other. In this elegant setting, diamonds are carefully placed in a row inside a channel, which normally extends along the entire circumference of the ring. This setting is most commonly used to strengthen the small stones. Diamonds may be located either around the entire ring or just in a particular part of it. The ends of the metal channel are sealed with smooth seams, thus creating an overall beautiful visual effect. A ring that features diamonds in a channel setting looks sophisticated and chic.

The Open Invisible Setting best12

The open invisible setting was invented by Van Cleef & Arpels in France in the late 1920s in France. In this setting, diamonds are mounted in an invisible frame. The advantages of this impressive setting is that different colored stones can be used and they are perfectly positioned to receive maximum light exposure and, thus, maximum illumination. However, this setting is incredibly labor-intensive and requires special training and equipment to perfect.
The open invisible setting is unique in that it creates the effect of having one large diamond by using four or more small ones held tightly together with no apparent space or metal between them. The secret to this technique is time. The diamonds are intricately inserted into a gold-mesh frame, which resembles a stained-glass window, with their edges tightly fit together. This forms a continuous top surface. Below this sparkly surface hide the diamonds’ edges, in a thin, golden framed connecting strip. Depending on the size, color and clarity of the individual diamonds used, the end result will be a radiant illusion of one large, gorgeous diamond.

The Tension Setting best13

The tension setting is very topical, trendy and popular among jewelers. In this setting, the diamond is placed in a separating slot, or groove, and secured to the ring by pressure coming from either side. The diamond looks as if it is being clamped with great force. This setting allows light from almost all sides to penetrate the diamond, thus creating a stunning shine and radiance. However, the tension setting is not recommended for those who live active lifestyles.

Set a Budget.

Decide on a budget and stick to it. With so many diamond jewelry options, it’s easy to get carried away. Consider compromising on carat size and clarity rather than cut. While half sizes and most inclusions are not noticeable, lack of sparkle definitely is.
