Color is one of the criteria used to determine a diamond's rarity, and there are many variations. These hues result from the stone's impurities. Generally, diamonds sold in jewelry stores have a transparent coloration. However, upon close examination of certain specimens, a slight yellow pigmentation may be visible. In this case, the diamond's color depends on the degree of white pigmentation.
What are the different color varieties of diamonds?
White diamonds are the most common type sold on the market. This means they are far from rare. A diamond is considered extremely rare if it has natural hues, such as pink, red, or green. You might even learn that black diamonds exist. The stone is composed exclusively of carbon atoms. It is created through a crystallization process linked to intense pressure within the Earth's crust. Light waves are not absorbed by a white diamond. The eye reflects the light, hence its crystalline appearance.
During the crystallization phase, other atoms join the carbon. These elements make their way into the graphite. In yellow diamonds, nitrogen atoms have replaced some of the carbon atoms. Mixing with boron produces blue diamonds. Exposure to uranium irradiates the gem, turning it green. Contact with hydrogen will produce violet hues.
Red and orange diamonds result from a lack of transparency during their formation. The stone is created before its ascent into the Earth's mantle, where it undergoes compression. This deforms the lamellar bands, and the presence of inclusions is also observed.
What are the uses of diamonds depending on their color?
Diamonds are used in jewelry making for their hardness. They are also used to design cutting tools. Rare varieties are used in the manufacture of jewelry such as necklaces and earrings.
Watchmakers, for their part, harness their brilliance for their timepieces. The manufacture of luxury watches employs the gem-setting technique. This is an assembly method used in the jewelry industry. Simply put, the metal surfaces of the watch will hold the diamonds.
The main challenge is avoiding drilling or glue. Part of the metal will be bent to create a sort of joint. Setting methods vary. The choice will depend on the size of the gems and the desired effect. Among the options available to a jeweler, we can mention, for example, channel or grain settings.
How do we classify diamond colors?
White diamonds are often described as colorless. Given the rarity of other colored diamonds, white diamonds are highly sought after. That said, prices vary depending on their clarity grade. As previously explained, some diamonds exhibit yellow tints. To highlight these differences, there is the GIA grading system. The GIA is the organization that established this system. The grading ranges from D to Z. Tints are considered light when the diamond does not exceed F. D represents the purest white diamond. With grades approaching Z, a pronounced yellow tint is often used. This is where the term "fancy color" comes in. Fancy color can range from light to intense, vivid to dark.
What are the values of diamonds?
The white diamond graded D is formerly known as Jager. The E grade was previously called River. It is difficult to discern a noticeable difference between it and the D grade. It is also colorless and could deceive the eye. When acquiring a valuable diamond, it is recommended to choose one of these grades. Professionals will rely on a reference sample to distinguish between the two types of stones (D and E). The difference is minimal.
Grade G is designated as extra white+. From this grade onward, the white will begin to blend with a slight yellow pigmentation. However, it will still be difficult to detect with the naked eye. All three grades are highly sought after, hence their high price.
But be warned, fancy color diamond prices have skyrocketed in recent years. There are pink and red diamonds. These two are comparable in cost to blue and green diamonds. Gray diamonds, on the other hand, are less sought after, while brown diamonds are relatively inexpensive. It's also important to know that a diamond can be a mix of colors, such as orange-yellow.
What external factors affect the color of a diamond?
The way stones are cut can alter their original appearance. In this respect, two scenarios are possible: either the color is accentuated, or it is neutralized. The setting, in particular, has an impact on the appearance. A setting with yellow gold will give a yellowish tint. This is all due to the reflection of light on the bands. In addition to the cutting methods used, the shapes also play a role in the coloration. Some shapes reflect more light, which can result in some of the color being muted. Furthermore, shades of yellow are difficult to highlight with heavier stones.
FAQ
What is the best color diamond?
The white diamond, graded D on the GIA scale, is the best diamond color on the market. However, fancy colored diamonds are gradually gaining popularity.
What is the rarest color for a diamond?
The blue diamond is considered the rarest of all the gemstone's shades. It originates from a greater depth in the Earth's mantle than colored gems.
