Fancy colored diamonds are known world-wide as extremely rare. The captivating allure of yellow diamond is their rarity, fire, and brilliance, which makes them most attractive.
Fancy yellow, also known as "canary" diamonds represent natural yellows. The term "fancy" covers a broad spectrum of hues and saturation. "Fancy yellow" stretches in saturation from straw to lemon through to taxi-cab yellow.
Natural yellow diamonds are graded by their different shades of yellow;
Fancy vivid yellow
Fancy intense yellow
Light fancy yellow
All are determined by the amount of impurities - "a nitrogen concentration trapped inside a diamond." This does not affect the brilliance of the diamonds.
One of the increases in popularity of fancy yellow has been caused by celebrities who have jumped on the band-wagon and adopted yellow diamonds as the newest hot diamond trend due to their extreme rarity.
Diamonds have no shelf life. They don't age, never look old, and never lose their sparkle. A 100-year-old stone looks as new as if it was just polished five minutes ago.
In the end, fancy vivid, fancy intense, fancy yellow...fancy schmancy, "A diamond is forever."
