Our Story

TopMin was founded by Stefan Plueth and Julius Eschkoetter, two German-born collectors who each bring distinct qualities to our brand. Together, decades of expertise meet a fresh, global perspective — united by a commitment to sourcing and offering exceptional mineral specimens from renowned localities worldwide.

The Founders

Stefan Plueth

Stefan's journey with minerals began in 1970 at just 10 years old, igniting a lifelong passion that has spanned over five decades. His expertise and particular affinity for fluorite specimens have become his signature, with a special focus on the exceptional varieties found throughout Spain.

Years of field collecting across Spanish mineral localities have given Stefan an unparalleled understanding of fluorite crystallography, color variations, and formation conditions. His extensive knowledge and discerning eye ensure that every piece we sell meets the highest standards of quality and authenticity.

Julius Eschkoetter

Julius's entrance into the mineral world came in 2021, sparked by an unforgettable experience in Pakistan where he witnessed miners extracting aquamarine firsthand. This transformative encounter revealed the raw beauty and geological wonder of minerals at their source.

Since then, Julius has immersed himself in the international mineral community, attending and exhibiting at the world's most prestigious shows including Tucson, Denver, Munich, and Sainte-Marie-aux-Mines. His fresh perspective and dedication to sourcing exceptional specimens from mining sites around the world bring a dynamic energy to TopMin's inventory.
