Current Auctions


A great selection this week with plenty of attractive, good quality, rare and unusual specimens.  Look for new discoveries that we picked up at recent shows or direct from the source, along with collections like David Burgess, Gary Weaver and Bill Logan along with plenty from Kay Robertson!  You might even find the occasional fossil, lapidary or gem item from time to time.   Look here for the not so typical mineral specimens along with plenty of your favorites.  We don't just offer the "standard 20 species", but an eclectic mix of specimens that appeal to everybody!

1. Attractive deep red UVITE TOURMALINE on matrix from Brazil
