This gem was cut by Dr. Grey Weaver from his rough. This rough was bought back in the late 1990's. It is a saturated gem but the red and purple flashes that come off this gem are very lovely and it is not a common color for gem tourmaline. No heat or any other type of treatment. It is a very fine large gem tourmaline. This gem was a 8.22 carat gem that He had cut into a brilliant design; but it robbed the gem of any internal light; so the re-cut lost half the weight; but restored life to the gem...
