Just a great Ethiopian Opal here, polished myself with a full diamond polish up to 100,000 grit.  Many stones you buy online don’t have the best polish.  Diamond polish is expensive and a lot of sellers skimp on the higher grits to save on cost.  But when you see the mirror finish of our stones, the difference will be clear.  

This stone is around 3.5/5 to 4/5 for brightness, which is a little bit more subdued than we usually like to sell.  But this Opal has a nice, semi-black base color to it, which is pretty rare for Ethiopian Opals.  Nice color from all over the surface of the stone, with good variety—Reds, Greens, Oranges, Cyans, Yellows and even some Blue and Purple.  

I   took pictures of this Opal in high magnification and full sunlight to give   you the best idea of its color play and quality.    As a certified   gemologist I can verify that the above description is       accurate and   that this Opal/Opals have been tested in the gem lab to   verify   identity and natural origin.
