7ddcena ((STILBITE on CALCITE)), MINIMUM BID $35, Madan, Bulgaria, 16 x 12 x 4.5 cm, Large Cabinet, | |
There are thin wafer like crystals of Calcite on matrix. On these thin crystals is secondary covering of crystals. They label just says Calcite but these look like the Stilbite coffin shaped crystals. Mindat reports that Stilbite is found at the Davidkovo Mine in Madan. Although no photos are available, I believe this is in fact Stilbite on Calcite. The Stilbite are very lustrous and there is no damage. A very fine Bulgaria specimen. ex Ernie Schlichter. |
