9idcens ((PHOSPHORESCENT? LIMESTONE)), Phila Academy of Sciences, $10 MINIMUM BID, Utah, 8 x 6.5 x 6 cm, Cabinet, | |
Here is a specimen from Utah from the Philadelphia Academy of Natural Science #5745. Old Museum label. It is a little fluorescent but not that bright. Numbers match but it does not look alot like Limestone. Its a bit of a mystery rock to me. |
