LL881 - Dioptase Ray Mine, Pinal Co., Arizona, USA cabinet - 13 x 8.5 x 4 cm
Beautiful large specimen of Dioptase on drusy Quartz over Chrysocolla and Malachite. This looks like something out of Africa rather than the USA, but it's old Arizona material with large isolated Dioptase crystals to 7mm in size. A big and colorful Arizona classic that will add pop to a mineral case.
LL24 - Mottramite on Calcite Tsumeb, Namibia cabinet - 9.5 x 5 x 5 cm

ST360 - Tourmaline St. Anne's Mine, Miami, Karoi District, Zimbabwe small cabinet - 6.5 x 4.5 x 3 cm
Large, dark green single Tourmaline crystal from recent production at this famous mine in Zimbabwe. Tourmaline has been very rare from this mine historically, which has primarily targeted blue Topaz.

There is a bit of edge chipping along the sides, it's complete all around, and has a perfect termination. Weighs a hefty 153 grams.
