GT0611120010 6 Ct. Asscher cut VVS1 Color BIANCO diamonde. In 1983, a Russian scientist developed a method of growing crystals with many of the same characteristics of a natural earth mined diamond. The new stone was then cut, using the same process of diamond cutting and the end result was a creation branded inBIANCOin. These stones are not to be confused with reproductions or cubic zerconia. They naturally come with or without inclusions, of different colors and are scaled like a naturally grown diamond. Like a diamond, they are so hard they cut glass. This stone is free from inclusions and is magnificent in cut and clarity. Purchased in 1983 for$250 per carat or $1,500 (comparable to $15,000 in todays market), the stone is as perfect as the day it originally sold, with no marks, scratches, or abuse.
