Today’s topic is Brown, Chocolate, and Coco Diamonds. What is the difference? NOTHING. They are all the same diamonds with different names. Brown diamonds are natural diamonds in that they are not heat treated like most black, blue, yellow and pink diamonds. Levian trademarked the name “Chocolate diamonds” in 2000. So, when you hear about stores carrying Mocha, Brown, Champagne, Congac, and “Chocolate diamonds”, know that they are all simply brown diamonds.
