About Astro West:

Astro West is owned and run by Marc Tanjeloff, a third generation mineral dealer and collector. His grandfather Julio Tanjeloff turned Astro Minerals into a lavish 16,000 square foot gallery showcasing items from all over the world, from fine minerals to African art, and created the periodical Mineral Digest along with newly discovering the mineral Tanjeloffite, more commonly known as Tanzanite.

Marc’s new venture Astro West pays tribute to his grandfather and focuses more in-depth on mineral collecting. Marc was drawn further into the mineral game early on in his career through meeting and becoming involved with the extensive collection of mineral enthusiast Marc Weill. In addition, Marc Tanjeloff worked with the prominent collector Lida Hill to build her collection through the 2000s (a collection which eventually extended into the Lida Hill Hall of Minerals in Dallas). In 2008, Tanjeloff had started a collection of minerals with Chris Burch (who was interested in Marc’s name and partnership) and someone brought an incredible tantalite/sphene specimen to Marc's attention. The very next day Astro Mining Incorporated came into existence and Marc was on a plane to Tanzania, where he bought land and built a company with Burch. The deposit town where they mined for the sphene was called Rudi and located in a state called Dodoma and while there the men built a school and brought healthcare by government issue to around three hundred people. The finest piece accrued was a specimen of tanzanite weighted 2.5 kilos which currently resides in the Rower Collection.

After this find, Marc left Africa victorious. Two years later, a son on the way inspired him to expand the family business to a new location on the West side that brings his discerning eye and passion for fine minerals to every customer and every piece.
