An opal and diamond stickpin, circa 1900, the tapered polished opal bead in a shaped cup setting above an old brilliant-cut diamond, mounted in silver and gold, case signed ‘James Aitchison’, terminal length 17mm. £160-£200

Gross weight 1.3gm.
Case is in reasonable condition with just a few scuffs to the exterior.
