Opal Diamond Jewellery
Opal diamond jewellery pairs the shifting play of colour in opals with the bright flash of diamonds in rings, brooches and pendants.
Opal Diamond Jewellery
When you search for opal diamond jewellery, you encounter pieces spanning the nineteenth century through the mid-twentieth century, with Victorian, Edwardian and Art Deco examples appearing frequently. Rings form a large portion of the selection, particularly boat rings, cluster configurations and multi-stone settings executed in yellow and white gold.
Pendants, drop earrings and brooches also feature in the listings, alongside bracelets set with cabochon stones. The designs range from traditional nineteenth-century flower motifs and clover brooches to geometric twentieth-century cluster pendants and contemporary classic styles.
Materials span white and yellow gold in nine-carat and eighteen-carat standards, alongside platinum and silver mounts that frame white, black, boulder and fire opals alongside cut diamonds.
How these pieces were constructed
The construction relies on precious metals such as eighteen-carat yellow and white gold, platinum and silver to form settings that secure the central opals and surrounding small diamonds. Master jewellers shaped these metals into cast and fabricated mounts, including boat-shaped galleries, multi-stone clusters and platinum-topped gold settings typical of the Edwardian era.
Opals are predominantly shaped as smooth cabochons to display their internal play of colour, while diamonds are cut in various traditional facets to provide contrast and brilliance against the iridescent stones.爪 settings, bezel settings and claw work secure each gem firmly within the metalwork.

What determines quality in these items
Quality rests primarily on the optical properties and stability of the opal itself, where vibrant play of colour across the surface and strong internal fire distinguish superior specimens from muted stones. The cut and clarity of the accompanying diamonds further influence the overall refinement of the piece.
The weight and integrity of the gold or platinum mount also signal standard, with heavy, well-preserved settings and crisp hallmarks indicating superior manufacturing origin and careful preservation over time.

The Opal Diamond Jewellery Glossary
- Cabochon
- A gemstone shaped and polished with a smooth, convex surface rather than faceted edges. This style highlights the natural play of colour in opals.
- Boat ring
- A ring featuring an elongate, curved setting reminiscent of a boat hull. This silhouette accommodates a central stone flanked by smaller gems.
- Cluster ring
- A jewellery design featuring a central stone surrounded by a tighter ring of smaller gems. In these pieces, an opal typically forms the centrepiece encircled by diamonds.
- Doublet
- A composite gemstone made of two layers glued together, often a thin slice of opal backed by ironstone or dark material to enhance colour. This technique strengthens the stone and deepens its appearance.
- Trilogy ring
- A ring set with three stones representing past, present and future. These pieces frequently pair an opal centre with diamond side stones.
Opal Diamond Jewellery: Frequently Asked Questions
How should I clean opal diamond jewellery?
Opals contain water and are softer than diamonds, requiring gentle care to maintain their integrity. Clean them using a soft cloth and warm soapy water, avoiding harsh chemicals, ultrasonic cleaners and steam.
Because diamonds are much harder than opals, structured mounts can sometimes cause friction if settings loosen over time. Regular inspection by a professional jeweller ensures both gems remain secure in their mountings.
Can I wear an opal ring every day?
Opal rings require mindful wear because opals rate lower on the Mohs hardness scale than diamonds and rubies. Daily wear is entirely possible if you exercise caution against sharp impacts and remove rings during strenuous physical tasks.
Choosing bezel settings or cluster designs provides extra metal protection around the edges of the opal. Storing pieces separately prevents harder gems like diamonds from scratching the softer stone surfaces.
What is the difference between white and black opals?
White opals display a milky or light body colour with flashes of spectral hues playing across the surface. They offer a delicate and luminous appearance typical of many nineteenth-century pieces.
Black opals feature a dark body tone ranging from dark grey to jet black, which causes the internal play of colour to appear intensely vivid. This dark background creates strong contrast against the surrounding diamonds.
How do I identify an Edwardian opal ring?
Edwardian opal rings often utilise platinum-topped gold settings that allowed for delicate, lacy openwork and fine millegrain details. The metalwork reflects a light and airy aesthetic distinct from heavier Victorian designs.
These pieces frequently combine cabochon opals with small rose-cut or old-cut diamonds in boat or crossover configurations. Hallmarks and stamps on the inner band often help confirm the period of origin.
