Large, complete single Azurite crystal from the Milpillas Mine. This is a floater well crystallized all around. There is some minor chipping present, but overall it's in good condition. Nice to find a complete single crystal like this. Both sides shown in photos.

Transparent blue Fluorite crystal from the Yaogangxian Mine. So water-clear you can see right through it to the Muscovite attached to the bottom (photos don't convey this transparency well). Complete all around, stunning crystal of the quality the Yaogangxian mine is famous for. A small cleave on one corner, otherwise perfect.

Cluster of glassy, transparent Rose Quartz crystals from Brazil. This cluster features a particularly well formed large individual crystal 3cm tall. Undamaged, fine quality miniature.

Colorful orange Gmelinite crystals on matrix. Ex. Tim Sherburn collection.

Blocky, barrel-shaped deep red Vanadinite crystals on matrix. The main crystal is an impressive 1.6 x 1.6cm in size. There is chipping to some small edge crystals along the left bottom, otherwise perfect.

Old specimen of blocky Chalcocite crystals on matrix. Lots of great crystals well dispersed across the top surface. The crystals have a slight blueish irridescence. This specimen was in the MG Weller collection and likely dates back to the 1800s. From MINDAT: From 1815 to 1897, Cook's Kitchen Mine produced 8,859 tons of black tin, 40,920 tons of 5.5% copper ore, 120 tons of arsenic and 222 tons of arsenical pyrite. It is said to have been worked for 130 years prior to 1874, and to have been one of the most productive mines in Cornwall in 1814.
