Australian opal is hydrated silica. Its shifting colours come from light diffracting through regularly arranged microscopic silica spheres. The stone, the surrounding rock and the landscape have different histories: the age of an ancient seabed is not the measured age of an individual opal.
Tosca Mine, also called Tosca’s Hope, is a documented turquoise locality on Ammaroo Station, in the Sandover area of the Barkly Region, Northern Territory. A 1974 exploration report held by the Northern Territory Geological Survey describes turquoise production and the deposit’s claystone layers.
Variscite is a hydrated aluminium phosphate, valued for its green colour and contrasting matrix. The Gascoyne region of Western Australia includes the documented Mount Deverell and Mount Deverell East deposits near Milgun Station.
Rhodonite is a manganese silicate. The Australian Museum distinguishes the massive pink material found around Tamworth from rare transparent red crystals at Broken Hill, both in New South Wales.
Pāua is the Māori name used for New Zealand abalone. Haliotis iris, the blackfoot pāua, is native to New Zealand. It occurs around the country’s coasts, including the North Island, South Island, Stewart Island and Chatham Islands; it is not confined to the South Island.
Many Australian desert sands owe their red and orange colours to iron oxide coatings on mineral grains. Sand is a collection of grains, not one gemstone or one mineral. Colour and grain size vary between locations.
Lapis lazuli is a rock made of several minerals, rather than a single mineral. Badakhshan in north-eastern Afghanistan, including the Sar-e-Sang district, is a historic source. It is one of two materials in our collection from outside Australia; the other is New Zealand pāua shell.
Australian opal from Coober Pedy and Mintabie in South Australia and Lightning Ridge in New South Wales; turquoise from the Tosca Mine in the Barkly Region of the Northern Territory; variscite from the Gascoyne region of Western Australia; rhodonite from Broken Hill and Tamworth in New South Wales; and red desert sand from our opal fields at Coober Pedy. Two materials come from outside Australia: pāua shell from New Zealand and lapis lazuli from Badakhshan, Afghanistan. Each has a story page with its sources.
How does the screw-back setting work?
Every stone sits in the same open-faced bezel, held by a backplate and two small screws. Undo the screws and the stone comes out, so one stone can move between a ring and a necklace (the bracelet is coming soon), and any Oli&J stone fits any setting. Desert Sands pieces are the exception: the sand is sealed behind glass on the front and back, with no screws.
Are the settings solid gold?
No. Settings are stainless steel, or stainless steel with a gold or rose-gold PVD finish.
Is the stone in the photo the one I receive?
Yes. Each Atelier stone is one of one: the stone picker shows the exact photographed stone, and once it is sold it is gone.
Is Mintabie opal still mined?
The Mintabie township closed at the end of 2019 and control of the land returned to the Aṉangu Pitjantjatjara Yankunytjatjara (APY) people. South Australian rules still allow authorised permit holders to mine the field under set conditions. Our Mintabie opal is cut from rough we have held since before the closure.
Who makes Oli&J jewellery?
Oli&J is Olivia and Juan. We cut every stone ourselves and trace each one to the field it came from.

I met Olivia and Juan during a market last year and instantly loved all the variety of products that were timeless and classy. I finally purchased a Lapis ring and have been wearing it everyday. I love that they are so humble and willing to go above and beyond to what your needs are for the perfect piece. They are easy going and reply fast to any inquiries. I can’t wait to keep an eye out of what they do next and look forward to purchasing more products!

I have an Australian abalone ring from Oli&J and I absolutely love it!!! The ring is just stunning and every detail is perfect. The customer service was also amazing. Juan really helped me find exactly the ring I wanted and made sure it was shipped safely, even though I live in quite a remote area. I’m really happy to own one of their pieces and I would completely recommend them if you’re looking for beautiful, high-quality jewellery.
