This highly aesthetic miniature specimen is a striking and rare combination of sharp Tetrahedrite crystals and micro Brookite blades nestled within a lustrous cactus quartz matrix. The overall visual impact is enhanced by the glassy brilliance and multi-crystallized surface of the quartz, which serves as a gem-like backdrop to the metallic, well-formed sulfides.

Butte, Montana is one of the most storied mining localities in North American mineral history. Renowned as one of the great classic districts for sulfide minerals, the Butte deposits have yielded hundreds of fine mineral species over a century of mining activity. It is especially celebrated for well-crystallized examples of Enargite, Pyrite, Tetrahedrite, and other copper-sulfosalts, though aesthetic matrix pieces like this one remain exceedingly scarce.

This piece captures a wonderful intersection of mineralogical interest and visual appeal. The tetrahedrite displays excellent geometric form with a subtle metallic sheen, while the delicate Brookite adds an uncommon and desirable association. The sparkling cactus quartz matrix gives the whole piece a refined presence, making it a superb representative of Butte’s legacy—especially appealing for collectors who value both locality significance and compositional beauty.
