Description
Rhoda Wager (circle of), an opal set silver brooch, Australia, circa 1930, unmarked, 4 cm long, SOLD
the opal has a back of sandstone, this could mean one of two things, that it is a thin seam of opal with the sandstone mother rock left to give it substance, or it could be a doublet utilising a sandstone rock as the backing, either way it is impossible to know for sure without unsetting the stone
