On September 14th, 2017, on the opening day of the 2nd largest Jewelry events in the World, The Hong Kong International Gems and Jewelry Fair, at the Asia World Expo venue, NCDIA (Natural Color Diamond Association), held a seminar for professionals in the diamond industry, called “Natural Color Diamond - Unique and full of surprises”.
As a member of NCDIA and one of the panelist, Ms. Paloma Sanchez shared her expertise in the natural color diamond field and her in-depth knowledge about the differences in characteristics of natural color diamonds and colorless diamonds, and how these differences could help inform sales and marketing of natural color diamonds.
Most diamonds, colored and colorless, have fluorescence under short or long ultra-violet (UV) light. While 100% natural colored diamonds have fluorescence when exposed to UV light.

Although fluorescence is seen as a flaw on colorless diamonds, it can also become a beauty factor when pricing lower-grade colorless diamonds. While in the case of natural color diamonds, their fluorescence does not affect their price since most of them have fluorescence.
Nowadays, fancy color diamonds are more popular than ever. Their abundant colors, intense luster and sparkles attract jewelry lovers. Natural color diamonds have almost all the colors in the color spectrum. They also have all the advantages that colorless diamonds have. But such a treasure is extremely hard to find in the earth. Only 1 in 10,000 diamonds are colored. Due to their rarity and aesthetics, they are among the most expensive gemstone species.
In April 2017, a stunning 59.6 carat diamond known as the "Pink Star" sold for $71.2 million at a Sotheby's auction in Hong Kong. This was and is still the highest price a gemstone has been sold for.
