Comment: Green sphene which anywhere near the sun showed too much yellow on photo. Only when we forced it into strongly artificial light the dominant green became visible; there mark the red fire sipping through the stone! As most sphene of high quality this gem has its own life and a new world of color and brilliancy opens every time one sees the stone again. Main color is an earthy olive green (less aggressive than image). Can be set in a protective gents ring. Absolutely clean sphenes in this size are rare.
