Fluorite, Mihalkovo Mine, Central Rhodope Mountains, Bulgaria Miniature 3.2 x 4 x 4.5 cm $250.
This is the finest crystallized fluorite I have acquired from Bulgaria. Nice light lavender color, good luster and exceptionally well formed. Typical fluorite from this location is minty green with small cubes of matte or etched surfaces. Superb provenance: collected by Mining Engineer Dobri Krastev Dobrev circa 1964; bequeathed to his son Krassimir; sold to North Star Minerals circa 2011. Exceedingly rare fluorite. In excellent condition.
