| 5ddshis ((CALCITE on QUARTZ)), $7 MINIMUM BID, Ophir Hill Mine, Ophir District, Tooele District, Utah, 10 x 8.5 x 4 cm, Cabinet, | |
 | These are the type of specimen that frequently had small octahedral Scheelite crystals. The specimens with Scheelite had the Calcite removed with HCl to expose the Scheelite crystals. Undamaged Calcite specimens are not too common since damage to the Calcite did not matter since it was usually dissolved. Calcite does fluoresce a red orange under UV. |
