TopMin is a newly established mineral venture headquartered in Dubai, founded by co-founders Stefan and Julius, and incorporated there in the belief that the regional mineral market is still in an early stage of development and offers significant potential for growth.

Stefan has been active in the mineral trade since the early 1990s and was among the first online mineral dealers worldwide, operating under the topmin.de domain. His collection includes exceptional fluorite specimens from Berbes, Spain, personally field-collected more than three decades ago.

Julius entered the mineral world after encountering aquamarine crystals directly with miners in Pakistan’s Haramosh Valley in 2021. Since then, he has been sourcing and studying fine minerals through major international shows, including Denver, Tucson, Munich, and Sainte-Marie-aux-Mines.

Our primary online gallery, topminerals.com, will launch in Q1 2026, offering a curated, gallery-style experience focused on quality, provenance, and aesthetics.

Selected highlight specimens will be presented on EarthWonders.

Julius will attend the Tucson Show 2026 to acquire new inventory and is always happy to connect with collectors and dealers.
