SOLD - 4.35 ct Boulder Opal and 1.56 ct Diamond, 14 ct Yellow Gold Cluster Ring – Antique


This exceptional boulder opal ring has been crafted in 14ct yellow gold with a platinum setting.

The low profile, pierced decorated platinum mount displays an elevated, collet set, feature 4.35 ct boulder opal* which has an impressive display of colour. (The iridescence is not truly reflected in the images or video).

The large opal is encircled with twenty Old European round cut diamonds totalling 1.56 ct, platinum set to the scallop shaped border.

The subtly tapering, elevated pierced decorated, platinum set ring shoulders blend seamlessly with the plain 14 ct yellow gold ring shank.

This fine boulder opal ring is supplied with an independent diamond grading report card.

This exceptional antique ring has been independently tested using state of the art technology (Niton XL2 Analyzer) and verified as 14 ct gold.

*NOTE Boulder opals are the second most valuable type of opal (following black opal). Boulder opals are easily distinguished by their layer of solid brown ironstone left on the back of the stone. Boulder opals, as the name suggests, are mined from large ironstone boulders under the ground. Thin veins of colourful opal forms in cracks and fissures in these boulders. Because these veins of colour are so thin, opal cutters need to leave the ironstone on the back of the opal to form a full sized stone. The thin layer of opal in boulder opals can display any colour of the spectrum resulting in a unique iridescence.


This exceptional antique cluster ring is fine quality, set with a stunning, original natural boulder opal and high colour graded old cut diamonds.

The boulder opal ring is an excellent gauge of gold and is in excellent condition.

Reflections in photographs may detract from the true representation of this fine piece of antique jewellery/estate jewelry.

The images do not reflect the true colours of the boulder opal. The video however provides a more accurate reproduction of the actual colour.
