SSAR08AC2.5 Gram Rough Black Opal-Allan's Rise Opalfield-Coober Pedy
In 2008 I came home from Oz with a lot of opal from Allan's Rise. Much of this opal had an iron oxide coating that obscured the play of color. So I spent a few days cleaning this opal and facing a number of rough Allan's Rise opals on the flat lap.
This particular stone was a huge surprise! Today (1/1/2018) I found 2 Allan's Rise stones while doing year end inventory and decided to run them a bit further on the flat lap...boom...explosive play-of-color appeared. Black opal from Allan's Rise with a unique northern lights like pattern.
Dimensions: 30mm x 21mm x 3.05mm thick. 2.50 grams. Scale=20mm.
