Opal & Diamond Ring
A very fine vintage opal and diamond ring. The ring is mounted to the centre with an Australian black opal with an exceptional vivid play of colour to asymmetric diamond shoulders. The opal is accompanied by a certificate attesting to its Black Ridge Mine origin. The diamonds are bright and lively, estimated to weigh a total of 0.10 carats combined. Hand crafted in 18 carat yellow gold and dating to circa 1990.
