Genuine solid boulder opal from Australia set in sterling silver.
The ring measures 19 x 15 mm and the shaft is 5 mm. wide.
The ring is a size 57.
Any change in ring size is included in the price.
The ring comes with a certificate of origin.
NOTE: Since it is a solid opal, it is resistant to water, but not to impacts and strong solvents.
Opal is also a relatively soft gemstone, and can therefore get small scratches with frequent use.
