The title is not a mistake made by my terrible typing. When I see a purple tourmaline that is rich and with good saturation, I know that I probably have a copper bearing gemstone and a rare color to boot. Unfortunately, the purple I can get out of Mozambique now (2013) is usually pretty heavily included, but it is purple. This smaller oval is sleepy from the inclusion and has a significant feather on one side of the table. Still it polish very well and is clean enough to flash its purple under both natural and incandescent light. I bring up the stability of its color, because I just finish another purple and it is not stable. It is larger and has a darker tone level, but the same color when I look at it under natural light, But when I look at it under incandescent light all the purple leaves and the stone is gray! I call the cuprian tourmaline that makes that color change “Laurellite”. And why does one included purple oval not change color and the other included purple oval change color is a conundrum I wish I could solve. And I have tried.
