Opal flower studs

A limited edition of these opal studs, as opals are not fun to work with haha.
I will list them one at a time as opals can be quite different.

Approx 8mm across with a 2.5mm cabochon pure opal (not a triplet or the opal sliver with added composite sandwiching the sliver of opal)

Sterling silver flower, post and butterfly.
