An Art Deco three-stone ring dating from 1930, made in 19-carat yellow gold. The face holds a central oval cabochon natural opal displaying orange, green, blue, and red tones, secured in a claw mount. Flanking the opal are two brilliant-cut natural diamonds in claw settings. The band is smooth yellow gold. It measures 0.8 cm high, 1.7 cm wide, and 2.1 cm deep, weighing 2.3 grams, and is a UK size N 1/2. This piece fits a modern jewellery collection as a striking hand ornament suitable for daily wear or special occasions. The combination of the fiery centre stone and colourless side diamonds reflects the geometric elegance and glamour of the Art Deco period. The item is fully tested for 18-carat gold and is presented in excellent condition, ready to be worn or given as a gift.

FAQs

Art Deco rings created between 1920 and 1939 frequently combine geometric symmetry with colourful gemstones, often featuring central cabochon opals flanked by diamonds set in gold or platinum.

These rings are predominantly constructed from 18ct yellow gold, white gold, or platinum, housing natural play-of-colour opals alongside round or cushion-cut diamonds.

Authentic pieces display period hallmarks, hand-cut gemstones such as old European or transitional cut diamonds, and precise claw or bezel settings typical of early 20th-century metalwork.

A three-stone opal ring can be worn as a stand-alone dress ring or paired with simple contemporary gold bands to complement mixed-era jewellery ensembles.

Opals are delicate gemstones sensitive to moisture loss, sudden temperature changes, and harsh chemicals; clean softly using a dry cloth without submerging the ring in liquid.
