Hi 👋 I'm Iona! You can read about me HERE. I'm the artisan behind your next favourite jewellery piece.

Every opal you see here has been hand-cut by me, and every setting is designed with care in my Townsville workshop.

I don't believe in shortcuts or mass production — just honest craftsmanship, genuine Australian opals, and jewellery that's made to be treasured for a lifetime.

It's not just me though — my husband and my dad help me with workshop improvements, maintenance, and most importantly, deliveries. We're a very small family business, and we're proud to be part of the Australian Made Campaign.

I'm always happy to have a chat if you'd like to know more about a piece, opals in general, a custom design idea, or even just more about me.

We thank you so much for supporting our small Aussie business 💛 Iona

Yes, but like all fine jewellery, it should be worn with care. Remove your opal pieces during heavy work, sports, or when using strong chemicals.

In some cases we can resize opal rings, but the design and stone setting will determine what's possible. Contact us for advice before sending your piece.

Sterling silver naturally develops a patina over time. To keep it looking bright, use a soft silver polishing cloth. Avoid exposure to chlorine, perfume, and harsh chemicals, and store your silver pieces in a sealed pouch or anti-tarnish bag when not in use.

Solid opals are natural stones cut from a single piece of opal. Doublets and triplets are thin slices of opal glued to a backing (and in the case of triplets, topped with a clear cap). We only sell solid Australian opals for their beauty, durability, and lasting value.

Crystal opal is semi-transparent with vibrant colour play visible through the body of the stone — often found at Coober Pedy.

Black opal has a dark body tone (N1–N4 on the grading scale), which makes the colours appear more vivid and intense. Lightning Ridge black opals are considered the most valuable opal in the world.

Boulder opal is found naturally bonded to its ironstone host rock in Queensland and is cut with the matrix left in place, giving each piece a distinctive, earthy character unlike any other opal type.

We source directly from Lightning Ridge, Coober Pedy, Mintabie, Yowah, Opalton, Winton, and other reputable Australian opal mining areas.

Yes, solid Australian opals are naturally stable and safe to wear in normal conditions. Unlike doublets, triplets, or Ethiopian opal, solid Australian opals won't be damaged by water.

No — that's a common myth, and it applies to Ethiopian opal, not Australian opal. Ethiopian opal is hydrophane (it absorbs water), which can temporarily affect its appearance. Solid Australian opals are stable and don't require oiling, hydrating, or any special storage treatment.

Store your opal jewellery in a soft pouch or lined jewellery box to prevent scratches. Avoid storing it with harder gemstones that could mark the surface.

Body tone refers to the base darkness of the opal, graded from N1 (black) through to N9 (white or milky). Darker body tones tend to make the opal's colours appear more vivid and contrasting — which is why black opals from Lightning Ridge are so highly prized. Body tone is one of the key factors used to assess and value an opal.

Opal's colour play is caused by the diffraction of light through a microscopic grid of silica spheres inside the stone. As light passes through these spheres, it bends and splits into spectral colours — like a natural prism. The size and arrangement of the spheres determines which colours appear, which is why opals flash and shift as you move them in the light.

Opals form over millions of years under unique conditions. Each stone's colour play, pattern, and shape are completely individual, making every opal truly one-of-a-kind.

We want you to be completely happy with your purchase.

Workmanship Warranty

All jewellery created by Iona Opal Australia is covered by a workmanship warranty. This covers faults in the metalwork and setting — including construction, soldering, and the security of the setting — in accordance with Australian Consumer Law. If a fault in workmanship is identified, the piece will be repaired or remedied as required.

Opal & Gemstone Disclaimer

Opal is a natural gemstone and can be sensitive to impact, pressure, and temperature changes once worn. While every opal is carefully selected and monitored for stability before setting, opal gemstones are not covered under warranty for cracking, chipping, or breakage after the piece has left the workshop. These are considered inherent risks of natural opal.
