Benitoite and neptunite on a white matrix. The specimen is about 5 inches wide.

A large, almost heart shaped specimen of dioptase. It's massive at about 7 inches wide.

An australian opal that shimmers vivid greens on one side and a little bit of blue and purple on the other. It's about 5 inches wide.

Several small uv reactive mineral specimens. They are (presumed) uranium glass, alexandrite (only weakly UV reactive), mangano axinite, hackmanite, and hyalite opal.

Just got back home from tucson! I got a lot of cool stuff while I was there. #benitoite #neptunite #dioptase #opal #uraniumglass #manganoaxinite #alexandrite #hackmanite #hyaliteopal #mineralcollection #minerals #hevrocks

Dioptase (turquoise crystals) and mimetite (yellow crystals).

Conichalcite and celadonite (both are green).

Linarite (blue) on barite.

Hyalite opal (green fluorescence) and lemon opal (yellow fluorescence). No lead or arsenic in either but at least the hyalite may have trace amounts of uranium contributing to the glow.

Some more minerals I got on my recent trip! A bunch of these remind me of other more benign minerals, but actually contain lead and/or arsenic.
