Australian opal in its original rock matrix. You can actually see the vein that the opal flowed along in its original liquid state to reach this cavity that now glitters in so many colours.
I have set it in a burnished rub over setting with detailing to the clasp and back, all cut out by hand.
This pendant can be worn either way round and is in solid 925 silver.
18x14mm and 4mm deep.
Wieght, 10.5 ct (2.15grams).
