Three different prominent mineral collectors told me to make sure I saw the tanzanite exhibit on the main floor of the Tucson Gem & Mineral Show yesterday. My amateur snapshots don't do it justice.
In addition, John Rankovan, helping staff the Mineralogical Society of America booth, showed me a beautiful diopside crystal from a new discovery in the tanzanite deposit in Zambia. It was brilliant green and more transparent and clear than any either of us have seen.
