Yellow Diamonds are the most abundant of all diamonds in the world. The aesthetic quality and value of Yellow Diamonds increase as the intensity of the yellow increases. When purchasing diamonds, we use only Yellow Diamonds that pass the threshold into the Fancy Yellow realm. Over the past 30 years we have learned the best ways to maximize the strengths of each Yellow Diamond. Through tiered and angled halo settings, we are able to give each Yellow Diamond a more intense appearance and the illusion of a stone that appears larger than it actually is. With a Gregg Ruth Fancy Yellow Diamond, you will be getting a piece of jewelry that is designed to maximize the unique qualities of each diamond, making each piece truly one of a kind.
