This incredibly bright crystal opal is actually an opalised mussel shell! A super high quality gem mined at the 15 mile field, Coober Pedy, SA, and measures approximately 11 x 8 x 4mm.
The 6.7gm 18ct yellow gold setting was made from a one of a kind hand carved wax mold. The level of technical skill in this piece is astounding.
Ring size M.5 (6.5 US), but can be adjusted up or down by request, or easy for any other jeweller to do.
