Continuing with our special themed auctions through the summer we are thrilled for our next installment of the worldwide collection of Tom Campbell.

Tom is a mineralogist and mineral collector who works with us here at The Arkenstone. He has over 35 years' worth of experience in the fields of exploration geology, mining, and applied mineralogy, but he has even more years under his belt as a collector. He's been passionate about minerals and mineralogy his entire life, and has assembled a wonderful worldwide collection. In addition to collecting, Tom discovered the species Tiptopite, Fransoletite and Pahasapaite along with co-describing eight more new species.
