- Smithsonite var. Cuprian
- Miniature, 3.2 x 2.3 x 2.1 cm
- 400 stope, 79 Mine, Hayden area, Gila Co., Arizona, USA
- Ex. Kay Robertson
Lovely and old 79 Mine Smithsonite of the BEST intense and rich green color from the famous finds there (two major pockets and some minor ones, in the 1990's as I recall). This botryoidal layer has terrific luster and the crystals are quite translucent, glowing a nice apple green when backlit. Only a few of this quality - such a good luster and color - have come out, so these are still quite prized. Later efforts at mining have not reproduced the success of the original finds. This is a small miniature "toenail" size, and gorgeous in a case.
