Forstenite is a Man-Made gemstone and produced by Morion Co. www.morioncompany.com
In rough form it’s $7.00 a carat. Considering a good cutter loses up to 65% weight when cutting a piece of rough, that makes this an expensive substitute for the real thing. However, it is now very difficult to find Tanzanite rough in these sizes that are facet grade. It was easy to cut, but difficult to polish. At least with the techniques and equipment I used. Enjoy!
