01cgxlr ((water worn QUARTZ)), $10 MINIMUM BID, Minas Gerais, Brazil, 6 x 5.5 x 3 cm, Miniature, | |
Here is a river worn round gemmy clear Quartz nodule which has been cut and polished at one side. It shows the interior with some small rainbow prisms of colored light which are hard to photo. I think these are called window Quartz. |
