Schwethelm reserves & Siber+Siber reserves 
We've managed to obtain a few high end, mostly European specimens from the world famous Schwethelm collection (of which we are offering quite a few excellent pieces already - click here). Plus, we decided to let go of a few excellent mineral specimens that we set aside some 30 years ago. Enjoy this selection of outstanding, classic specimens not often seen these days! Plus, consider the attractive prices for these classics... Click images for a larger view! |
