13btceis ((CALCITE, SIDERITE, QUARTZ)), $10 MINIMUM BID, Panasqueira Mine, Covilha, Portugal, 15 x 10 x 5 cm, Large Cabinet, | |
Here is a large cabinet specimen from Panasqueira. It has large rhombic crystals to 2.5 cm that I believe are Calcite rather than Dolomite. Small light brown Siderite crystals cover Quartz at the bottom of the specimen. |
