Natural History

Bonhams Natural History department holds multiple auctions a year in Los Angeles and online, firmly establishing us as the forerunner in the field internationally. We offer a wide range of categories, such as mineral specimens; fossils (including dinosaurian), petrified wood, amber and ammolite; unmounted faceted gemstones (including rare phenomenal gemstones); gold; meteorites; lapidary, archaeological stone artefacts; mounts and animal, plant, insect and shell specimens, pearls and coral, and natural history-related decor and curiosities.

With consignments pulled from private collections, palaeontologists, fossil preparators, quarry and mine owners, we are able to provide many specimens that are fresh to market.
