Description
Few gemstones in nature possess the living, shifting luminosity of a fine opal — and this set of five oval-cut specimens, totalling 6.01 carats, captures that phenomenon in its most intimate form. Each stone dances with play-of-colour across a semi-transparent body, shifting and flickering as light moves across its surface. Presented without treatment, these opals arrive as nature intended: wholly authentic, wholly extraordinary.

Frequently Asked Questions
What is play-of-colour, and why does it make opal so special?
Play-of-colour is the optical phenomenon unique to precious opal, caused by the diffraction of light through microscopic silica spheres arranged in a natural lattice within the stone. As the angle of light or observation changes, vivid spectral hues — greens, blues, reds, and golds — shift and flash across the gem’s surface. No two opals display this phenomenon in exactly the same way, which is what makes each stone a singular work of nature.
Are these opals treated or enhanced in any way?
These opals show no indication of treatment, meaning they have not been artificially enhanced, coated, or stabilised. What you receive is the stone in its entirely natural state — a distinction that carries significant value among discerning collectors and jewellers who prize authenticity above all else.
How should I care for natural opal gemstones?
Opal is a gemstone that rewards thoughtful care. As a relatively softer stone, it is best kept away from hard surfaces, ultrasonic cleaners, and prolonged exposure to extreme heat or direct sunlight, which can cause the stone to dry and craze over time. Clean gently with a soft, slightly damp cloth, and store opals separately from harder gemstones. When set in jewellery, protective settings such as bezels are recommended to preserve the stone’s integrity.
Are the five oval opals in this set well-matched for jewellery use?
The five oval-cut opals in this set share closely matched dimensions — approximately 8.1 × 6.1 mm, 7.9 × 6.1 mm, and 8.0 × 6.1 mm — and a consistent semi-transparent clarity, making them well-suited for coordinated jewellery designs such as multi-stone rings, graduated pendants, or bespoke suite pieces. Each stone retains its own individual play-of-colour, lending a sense of harmonious variety to any composition.
