Learn about fancy coloured diamonds in IIG

When colors are mentioned in the Gems and Jewellery Industry, the first thing that comes to mind is color gemstones. Who would have known that fancy-colored diamonds are also available for jewelry and have been sold & marketed for ages?

Diamonds are known to be found in white/ colorless varieties universally. There is a market for fancy-colored diamonds, wherein the chemicals seep in to give the diamond a variety of colors. They have become popular over the years and are in demand due to their rarity.

The fancy colored diamonds are available in colors like red, pink, blue, yellow, purple, brown, grey, black, green, and orange. They are available in different tones and saturation. They are difficult to find and some colors are rare.

Let’s begin with learning about hue, saturation, and tone. 

Hue is the dominant color of the diamond. It can be affected by the presence of tints or modifiers. A pink diamond can have a second color like a hint of purple, hence called a pinkish-purple diamond.

Saturation refers to the strength or intensity of the hue of the main color like pink in a purplish-pink diamond. Saturation with a lighter tone can range from light to intense to vivid. Darker diamonds can range from dark to deep.

Tone refers to how light or dark the diamond appears. This is determined by how much brown, black, grey, or white is present in the diamond.

Grades such as light, fancy light, fancy, fancy intense, fancy vivid, fancy dark, and fancy deep are used for the appearance.
