Diamond and Opal Cluster
A diamond and opal cluster brings together the fiery play of colour in an opal with the bright flash of diamonds, forming a timeless centrepiece.
Diamond and Opal Cluster
A diamond and opal cluster centres on a prominent opal surrounded by a border of smaller diamonds, creating a striking contrast between the central stone and the surrounding gems. These pieces span several eras, appearing frequently in Victorian, Edwardian, and mid-century designs.
The format ranges from rings and pendants to brooches and stud earrings, with rings being the most common form encountered in this selection. Settings adapt to the shape of the central stone, from circular arrangements to elongated navette outlines.
Materials and construction methods
Goldsmiths utilised a range of metals to house these stones, including 18ct gold, 9ct gold, platinum, and silver, often combining metals such as gold and silver in earlier work to highlight the gems. Opals are typically cut as cabochons to display their internal play of colour, while diamonds appear in old cuts, rose cuts, and modern round cuts.
Setting techniques evolved across the periods represented, with claw settings, bezel mounts, and halo arrangements securing the stones. Heavier constructions appear in mid-century cocktail pieces, contrasting with the finer wirework seen in Edwardian examples.

Factors of distinction
Quality rests significantly on the optical performance of the opal, where vibrant play of colour across the stone elevates the piece above specimens with muted or dead patches. The integration of the surrounding diamonds also matters, with well-matched, lively stones enhancing the overall brilliance.
The integrity and weight of the metal setting contribute heavily to the grade of a piece, as robust mountings and careful claw work indicate higher workshop standards. Age-related alterations or replacement stones can diminish the coherence of a period piece.

The Diamond and Opal Cluster Glossary
- Cabochon
- A gemstone shaped and polished with a smooth, rounded surface rather than faceted. This style is standard for opals to display their internal colour play.
- Navette
- A boat-shaped gemstone arrangement or setting with pointed ends. This silhouette is typical of Edwardian cluster rings.
- Old cut
- A precursor to the modern brilliant cut diamond, featuring a smaller table, higher crown, and open culet. These cuts are commonly found in antique and Edwardian clusters.
- Play of colour
- The optical phenomenon where spectral colours shift across an opal as the viewing angle changes. It forms the primary visual appeal of the stone.
- Halo
- A concentric ring of smaller gemstones encircling a larger central stone. This configuration defines the classic cluster layout.
Diamond and Opal Cluster: Frequently Asked Questions
How do I care for my opal ring?
Opals contain water within their structure and are softer than diamonds, requiring gentle handling during daily wear.
Avoid exposure to harsh chemicals, ultrasonic cleaners, and sudden temperature shifts to protect the stone from drying out or cracking.
What periods do these clusters come from?
The pieces span from the Victorian and Edwardian eras through the 1930s, 1940s, 1950s, and 1960s.
Each period brings distinct mount styles, from delicate Edwardian filigree to heavier mid-century cocktail designs.
Are all opals solid stones?
While many feature solid natural opals, some listings include boulder opals where the host rock remains attached to the opal seam.
Solid stones display uniform backing, whereas boulder opals show natural matrix material on the reverse.
How are diamond and opal clusters worn?
These clusters serve as dress rings, cocktail pieces, pendants, and brooches depending on their original function and form.
Rings pair well with plain bands to let the colourful cluster remain the focal point of the hand.
