The chalcocite below, from Chimney Rock Quarry, is from my private collection

This chalcocite from the Chimney Rock Quarry is an important museum-quality mineral specimen that I acquired for my private collection many years ago. To the best of my knowledge, this is the largest and finest chalcocite specimen every collected at Chimney Rock. This quarry has not been accessible to collectors for the last 25+ years. Chalcocite, a rare mineral in New Jersey trap rock quarries, occurs at the boundary of two rock formations, where copper-rich solutions encounter impermeable layers above, causing copper minerals to precipitate, followed by late-forming calcite.

The ONLY reason I am selling this specimen is that it is too large for my display case.

I highly recommend this, without reservation, for collectors of top-quality minerals.

BOURNONITE FROM CHINA

Fifteen to twenty years ago bournonite specimens from China were readily available, yet quite expensive. The Yaogangxian Mine was producing fine specimens then, some worth up to $1 million. Bournonite is an uncommon (there are only 138 photos of bournonite from China listed on Mindat.org) sulfosalt mineral, with the formula: PbCuSbS3. Bournonite crystals are commonly complexly twinned, resulting in complex clusters of parallel twinned crystals, with parallel crystal faces, and if cyclic-twinned will exhibit the classic "cog wheel" habit.

The bournonite specimens below are from a stash that was collected in China around the 2000, and have not seen the light of day since they were collected. This is a rare opportunity to acquire this uncommon mineral in large crystals and at discounted prices compared to 15 years ago.
