Intense blue green diamond of 0.50 ct. modified... - Lot 15 - Millon Belgique
Intense blue green diamond of 0.50 ct. modified cushion cut, clarity VS1. What about natural bluish green diamonds ? Many talk about them, few have seen them... especially with a beautiful clarity and especially with an intense color. Here, the distribution of color is homogeneous but by looking at the diamond by the table, one sees thanks to the size a concentration of blue in the center which evaporates slightly on the edges towards the green. Normally, a diamond is only composed of carbon atoms but in the case of the blue colour, some boron atoms have slipped into the structure. This is rare because boron is not an element generally found deep in the earth where diamonds are formed. Only one boron atom in a million carbon atoms is needed to produce this bluish effect. The green color is produced by a very slight transformation of the carbon structure. Here are two imperfections that bring a crazy charm to stones that are highly sought after because they are rare in their natural state! GIA report number : 2145967765. Laser inscription GIA 2145967765.
