Diamond Story 7 – Exploring Fancy Color and Fancy Shape Diamonds

Diamond color is valued more when it is colorless and transparent, but very rarely, diamonds with deep colors, known as ‘Fancy Color Diamonds,’ actually increase in value due to their rarity.

Fancy Color Diamond
Fancy Color Diamonds are formed under extreme heat and pressure deep within the Earth’s mantle, just like colorless diamonds. However, during the crystallization process, minute impurities become part of the chemical formation, creating Fancy Color Diamonds. For example, nitrogen impurities create yellow hues, boron impurities produce blue Fancy Color Diamonds, and large inclusions can lead to black diamonds. These rare natural diamonds come in a spectrum of rainbow colors, including red, pink, orange, blue, green, purple, yellow, brown, gray, and black. According to GIA (Gemological Institute of America), Fancy Color Diamonds are formed at a rate of 1 in 10,000. Among these, red is the rarest, while yellow remains the most popular and widely appreciated.A 128.45-carat yellow diamond, discovered in the Kimberley Mine in South Africa in 1877. Designed by Jean Schlumberger for Tiffany & Co., it is called “Bird on a Rock.”

Fancy Shape Diamond
While Round Brilliant Cut is the most common diamond shape, Fancy Shape Diamonds offer unique brilliance and individuality. Fancy Shape includes cuts like Pear, Princess, Cushion, and more, each offering distinct styles and personalities. These cuts provide a balance of weight and reasonable pricing, along with distinctive designs that are gaining popularity among diamond enthusiasts.
