    RHODOCHROSITE
    N'Chwaning Mines, Kuruman, Kalahari Manganese Fields, Northern Cape Province, South Africa
    Manganese mines the world over tend to be some of the least attractive places to spend time, being over-supplied with VERY BLACK ore minerals that tend to break down into evilly tenacious dust that gets into and onto: Everything. Imagine their surprise when miners at one of these "black holes" in the Kalahari Desert found beautiful, transparent crystals of a most delicious strawberry-red hue, lining fissures in a recently blasted ore zone. Their surprise was quickly replaced by joy when they discovered the value of their find to collectors of beautiful minerals. The miners, who saved these red treasures, were very handsomely rewarded for their efforts, but sad to say, only two discoveries have been made to date, both around thirty years ago. Despite the entrepreneurial zeal of the many miners hoping to strike it rich again, no more have come to light. This very large and showy specimen, with individual crystals up to ¾ of inch long, came from the first find - over three decades ago. It has a profusion of rich cherry-red scalenohedral crystals that are highlighted with a light dusting of druzy Quartz/Calcite on the sides. The piece is in exceptionally fine condition for a specimen of its size - there are a few cleavages apparent on terminations of approximately 3 crystals and a small amount of the usual breakage around the edges, where the specimen was attached to wall rock - altogether these are very minor flaws that are difficult to detect, especially among the great abundance of Rhodochrosite crystals overall. The matrix is the typical dark black manganese oxide one usually associates with pieces from this locality. Very large and exceptional example of this classic, now rare, mineral. Overall measurements are 5¼ inches long x 3¼ inches wide x 1¾ inches thick.
