This is another gemstone that I did not buy as cuprian, but my spectroscope uncovered the proper absorption curves. It is very clean for a cuprian tourmaline from Mozambique, with only a very few light inclusions that do not effect the gemstone at all. This oval is cut with a three row step cut top and is very bright. I wish I know if copper was really effecting the color of this gemstone, but knowing that it contains copper is provocative. It weighs a beautiful 3.12 carats.
