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.
