Gorgeous .41ct untreated black Diamond solitare

This is an amazing diamond. It features a rich, black hue but, when held to the light, showcases a chocolate undertone. It has a top grade diamond luster that shimmers off of evey well cut facet. It measures 4.7mm x 2.9mm, and has a Mohs hardness rating of 10 out of 10, making it one one of the hardest gemstone in the world. This exotic example is unheated.
