TGMS 2008 - Bisbee

Last Updated: 2nd Mar 2008



I did a second video, because I wasn't sure how the first one came out. Try them both!



The minerals of Bisbee dominated a major floor-standing case - here we have tried to show as many of the specimens from this case as we can, broken down by mineral species.

Azurite



Bisbee is remembered for Azurite more than any other mineral. The following specimens are some of the most classic examples of the species from Bisbee.

Copper was abundant at Bisbee, although large crystals were relatively uncommon. Here are two of the better pieces from Bisbee:


Copper from Campbell mine. Les and Paula Presmyk collection

Cuprite



At Bisbee, Cuprite used to be an abundant ore mineral, but despite this well-crystalline examples were not common. Here are some of the best pieces:

Spangolite



This is quite possibly the world's best specimen of Spangolite, on a mat of acicular malachite crystals.

This particular specimen was also shown at the Munich Show in 2006, and I took some video of the specimen then. Here's a clip from that video:
