Greenstone Fine Mineralia specializes in fine mineral and fossil specimens. From tourmaline to fluorite, barite to aquamarine, calcite to amethyst we collect it all! For us it is all about aesthetics and uniqueness. We try to acquire pieces which are either aesthetically outstanding or otherwise unique in one way or another. Fine minerals are fine art, so color, form, condition, and provenance all play an important part in what we buy, collect, and put up for sale.

Our private showroom and gallery is located in Austin, Texas. Please feel free to contact us about coming to view our collection in person!
