Name: Black Opal Doublet.
Location: Lightning Ridge Opal field NSW.
Weight: 4.65 ct.
Comments: A really nice black opal doublet. A doublet is a Quartz cabochon covering over a slice of Opal .The idea is to keep moisture off the stone. Opal is not a durable stone so should not be worn 24/7. Dish washing liquid, detergents and other solvents including perspiration are not good for Opal. Wear the gem and remove it /them prior to using the above solvents. I have seen opal lose color within six months after constant use.
