622 ts ((CHRYSOCOLLA, MALACHITE, AZURITE)), $10 MINIMUM BID, Bertha Claim, Dugway Mountain District, Tooele County, Utah, 6.5 x 6 x 3.5 cm, Miniature | |
Locally the Bertha is known for its blue Chalcanthite. Unfortunately it is not the most stable of specimens and tends to fall apart over time. Recently local collectors have collected a few Chrysocolla, Malachite, and Azurite combination specimens. Here is one. |
