Learned a lot watching this presentation. I'm a proud thumbnail collector myself. Big crystals are always cool, but often the finest specimens are thumbnail size in most species.

Great presentation. I attended the university of New Mexico as well for my undergraduate, i don’t think the dorms have changed much!

Wow! What a beautiful tour! Also visited Tucson Museum in March 2022 and could hardly tear myself away. Spectacular. Thank you!

Thanks for posting this to KZfaq! I missed it on zoom!

The more videos I watch, the more I hear these people who invest in minerals, snap their tongue when they talk.
