About JenseniteHide

Cu3[TeO6] · 2H2O
Emerald green
3 - 4
Specific Gravity:
4.76 (Calculated)
Crystal System:
Named in honor of Martin C. Jensen (b. 1959) of Reno, Nevada, USA, who first found the material. He is a scanning electron-microprobe specialist at the Mackay School of Mines and mineral collector. He has studied and written papers/articles on many mines in the western United States, especially Utah and Nevada.
