Opal Rings & Opal Jewellery, Made in Melbourne

Opal is Australia's national gemstone, and almost all of the world's precious opal comes out of Australian ground — so it means something that ours are designed and set at our Frankston workshop. We keep a large range of opal jewellery and make opal rings to order at our own Frankston bench, from everyday pieces to heirloom-grade solid black opal.

Australian opal, by type
Black opal carries its play-of-colour on a dark body tone, which makes the colour blaze — the finest material is famously associated with Lightning Ridge, and it's the most valuable opal type. Boulder opal forms as veins through ironstone in the Queensland fields and is cut with its host rock as a natural backing — durable, characterful, and no two alike. White and crystal opal, the classic Coober Pedy material, runs from a milky body tone to a near-transparent one that lets the colour float inside the stone.
One distinction matters more than any of that when you buy: solid opal versus doublets and triplets. A solid is one natural stone — the choice for anything you intend to keep or pass down. Doublets (a bonded dark backing) and triplets (plus a clear dome) show strong colour for less money, and there's an honest place for them — but they aren't solid stone, they need drier care, and they should be priced like what they are. We'll always tell you which one you're looking at.
Opal engagement rings — the honest answer
Opal engagement rings are beautiful and personal, and we love making them — but opal is a soft stone (around 5.5–6.5 on the Mohs scale, against sapphire's 9 and diamond's 10), and a maker who doesn't say so isn't doing you a favour. Worn daily, an opal will eventually pick up fine scratches and lose some polish; worn thoughtfully, with the right setting, it can be a lifetime ring that comes back to the bench for an occasional re-polish.
The setting does most of the protective work: a bezel that wraps the stone's edge, or a low, well-guarded design, shields the opal from the knocks that side-set claws invite. If your work is hands-on or your lifestyle is rough on rings, we'll say so and design around it — or steer you toward opal as an occasion piece with a tougher stone for every day. Our settings guide covers the trade-offs, and our coloured-stone engagement ring guide compares the harder-wearing alternatives.
Set and finished by hand, in-house
Setting a soft stone is where bench experience pays for itself: seat pressure, claw tension and polishing heat that a diamond shrugs off can chip or craze an opal. Every opal piece we sell is set at our own Frankston workshop by jewellers who handle opal regularly — the same bench that repairs and re-polishes opals other stores won't touch, and that re-sets inherited opals into designs that get worn instead of stored.
Custom opal commissions follow the same process as our engagement rings — consultation, stone selection, your sign-off on the design, then the make. October birthdays make opal the obvious birthstone gift; anniversaries and remodels are the other jobs we see weekly.
Caring for opal
Hand-clean only: lukewarm water, mild soap, soft cloth. Opal never goes in an ultrasonic cleaner, and it doesn't like strong heat, sudden temperature swings or harsh chemicals. Solid Australian opal copes fine with daily life and ordinary water contact; keep doublets and triplets dry. Store opal pieces separately so harder stones can't scratch them. The full routine — including the checks that catch a loose stone early — is in our at-home cleaning and care guide.

No gemstone loses more in photographs than opal — the play-of-colour has to move to be believed. Visit the Frankston workshop (92 Young Street, Frankston VIC 3199), where walk-ins are welcome for the range and all opal services. Email us.
Common questions
Are opals suitable for engagement rings?
Yes — with eyes open. Opal is softer than sapphire or diamond, so an opal engagement ring wants a protective setting (a bezel or a low, well-guarded claw design), a wearer who's happy to take it off for gym, gardening and rough work, and an occasional re-polish over its lifetime. We'll tell you honestly whether an opal suits how you live before we make one.How do I care for an opal ring?
Clean it by hand with lukewarm water, mild soap and a soft cloth — never an ultrasonic cleaner, and keep it away from strong heat and harsh chemicals. Solid Australian opal handles daily life and normal water contact; doublets and triplets should be kept dry because prolonged soaking can affect the bonded layers.What is the difference between solid opals, doublets and triplets?
A solid opal is one natural stone through and through — the most valuable and the most durable choice for an heirloom piece. A doublet is a slice of opal bonded to a dark backing; a triplet adds a clear protective dome on top. Doublets and triplets show strong colour at a lower price, but they aren't solid stone and need drier care.Can you repair or replace an opal?
Yes. Our Frankston workshop re-polishes scratched or dulled opals, tightens and rebuilds settings, replaces lost stones and re-sets heirloom opals into new designs. Opal is soft enough that repair work belongs with jewellers who handle it regularly — it's bench work we do, in-house.Do you make custom opal rings?
Yes — opal rings go through the same custom process as our engagement rings: design consultation, stone selection, your approval on the final design, casting by a specialist casting house, then setting and finishing at our Frankston bench. Typical turnaround is 3–4 weeks from CAD sign-off.What types of Australian opal are there?
The classic Australian types are black opal (dark body tone with vivid play-of-colour, famously from Lightning Ridge), boulder opal (opal veins on natural ironstone, from the Queensland fields), and white or crystal opal (lighter body tones, associated with Coober Pedy). Australia produces the large majority of the world's precious opal, and opal is our official national gemstone.
