Spencer (Idaho) Opal Cabochon

$22.00 USD

The most famous source of precious opal in the United States is the Spencer Mine in Idaho.  This round cabochon is a Spencer "doublet" (a layer of precious opal with a layer of clear opal) and is about 6 mm diameter (about 0.2").

It's a good match with our second Spencer Opal cabochon to make a custom pair of earrings.
