Kirby and Eddie Siber Gold Collection
Crystal Classics is proud to present the world-renowned Kirby and Eddie Siber Private Gold Collection.
This extraordinary collection of gold specimens, assembled by Dr. Hans-Jakob "Kirby" Siber and his brother, Eddie, will exclusively debut at the Tucson Fine Mineral Gallery (TFMG) for the 2025 Tucson Gem & Fine Mineral Show.
Kirby Siber (Kirby is an Anglicization of his Swiss nickname, Kobi) has had a lifelong passion for minerals and fossils. Together with his father, Hanz (1905-1979), he founded the business 'Siber+Siber Mineralien und Fossilien AG' in 1964 by opening a shop in Aathal, Switzerland. With Eddie's help, beginning in 1967, the business soon gained international acclaim.

After decades in the mineral trade, Kirby's fascination shifted toward dinosaurs and other large vertebrate fossils. In 1992, he opened a museum dedicated to his discoveries, located just across the road from their mineral and gem business.
Alongside their passion for fossils, Kirby and Eddie also dedicated themselves to assembling one of the finest collections of gold specimens ever brought to market.
The result was a meticulously curated gold collection of 220 specimens, which was on display for nearly 50 years at the Siber+Siber store in Aathal, Switzerland until its sale. The displays, thoughtfully arranged with locality-specific memorabilia and historical artifacts, featured specimens from countries such as Alaska, Austria, Australia, Russia, Brazil, Bolivia, Venezuela, Canada, Romania, and numerous U.S. localities.

Crystal Classics owner Ian Bruce befriended Kirby more than two decades ago and had previously purchased part of his worldwide mineral collection. Towards the end of 2024, after months of negotiation, Ian successfully acquired Kirby and Eddie's private gold collection.
Since then, Ian, Diana, and the Crystal Classics team have packed and transported the collection to their showroom at the TFMG. They are now preparing the collection for display in the specially designed showroom named "Mini Fort Knox", just in time for the 2025 Tucson Gem & Fine Mineral Show, which runs from Friday, January 31 to Saturday, February 15.
