Legendary Mineral Dealer’s Collection Goes Up for Auction

New York—A selection of pieces from a pioneering mineral collector and dealer are heading to auction.

According to a website dedicated to the life and collections of Rock Currier, his early collecting days started in Boron, California, where he became interested in borates.

He then moved to New York, where he began building a photographic library of specimens and expanding his own knowledge of minerals and localities.

He decided to become a mineral dealer in 1972, making his first trip to India that year, and started buying for Jewel Tunnel Imports.

The late pioneering mineral dealer traveled everywhere in his search to source specimens and was pivotal in in developing mineral markets in India, Namibia, Peru, Brazil, Chile, Russia, China, and Mali, among other places.

While he was gathering specimens for sale, Currier also amassed an impressive personal collection. At the 2003 Springfield Show, for example, he displayed more than 50 cases of his own pieces.

He was also a prolific writer, and worked on behalf of online mineralogical database Mindat, sharing his knowledge and documenting what he knew about localities, including posting more than 10,000 messages on the site and sharing more than 10,000 photos.

He died in September 2015.

A selection of Currier’s personal collection is set to go up on the auction block at the upcoming Bonhams Lapidary Arts and Gems auction in Los Angeles on Oct. 26.
