A pair of highly lustrous Carrollite crystals attached to the face of a Calcite rhomb. Largest crystal is 1.1cm.

Sharply formed, lustrous black tetrahedral crystals of Sphalerite, some with small Sphalerites growing fromt he sides of the alrger crystals. Fine quality crystals.

Dramatic cluster of angular Silver crystals, capped by a superb 1.2cm crystal. Tiny amounts of Copper are present on some of the crystal faces.  Nothing but good, large crystals. Fine!

Amazing double terminated Apophyllite crystal atop stalactitic quartz. The Apop is 4cm wide. I used to import hundreds of Indian minerals years ago, and this one was one fo the select few out the many hundreds in those parcels that I kept for my collection.

Floater rosette of Pyrhottite, the best of a small lot purchased about 10 years ago.  These are not as well known as other minerals from Yaogangxian and are excellent specimens and a must for a Yaogangxian suite. Undamaged and pristine.

Well crystallized, arborescent group of Copper crystals with a nice patina.

Solid mass of Acanthite and Polybasite crystals - there are hundreds of Polybasite crystals along with tiny cubes of Acanthite. This specimen came out of a collection that was built in the 1970s, so dates back at least to the 70s.

Showy specimen of Cuprian Adamite on Calcite with crystals to 1.3 cm long. Good sized crystals that present dramatically for display.

Large white rhombs that reach 1.5cm wide in a near floater cluster - just one small point of attachment in center of backside. Bright white on the front with reddish brown colored crystals on the backside - crystals on backside are just as lustrous on the front. No matrix, nothing but very high quality crystals and no damage, very good specimen.
