Bright blue/green crystals of Botallackite on all sides of specimen. Botallackite is a rare secondary copper mineral and this is a very rich example from recent finds at Cligga Head.

Crystals of Calaverite, a rare Gold Telluride mineral, intergrown with Quartz. There are also areas of exposed Calaverite in the matrix.

Transparent, colorless single Euclase crystal from Brazil. It's a complete and undamaged crystal though there is a bit of Muscovite and Feldspar attached to the back termination. Uncommon gem crystal.

Crystal cluster of Tennanite after Azurite from Tsumeb. Elongated, primatic crystals of former Azurite that have been pseudomorphed to Tennantite. An undamaged floater cluster with individual crystals to 4.5cm in length.

Well formed, deep purple/red crystals of Sperocobaltite that contrast well against the white matrix. Ex. Erich Laskowski collection.

Botryoidal Malachite specimen from the Shilu Mine in China. This find produced Malachite with a wonderful velvety, chatoyant surface luster. The chatoyancy is very evident under bright lights or in direct sunlight, creating shimmering 'eyes' all over. It has bubbly botryoidal surfaces along the top with a lighter green, fibrous structure around the edges and all over the bottom. Undamaged and a good size for these (not too big, not too small).

Single gem crystal of Rhodonite from recent finds in Brazil. This is a complete crystal with typical stepped termination growth and small raised crystal growths on some sides. There is a tiny edge chip, otherwise it's perfect and undamaged, and transparent internally. Superb color!
