Altmann + Cherny - Opal Specialists, Since 1948

We bought my daughter a lovely opal necklace for her birthday there. We were in Sydney Australia over New Year’s weekend. We have just now given her the necklace. She loves it! My grandmother loved opals. I’m sure she’d be pleased with the piece. As soon as I saw it I knew my daughter would love it. It was just so strikingly different. The staff was very helpful and kind.

I was first drawn to the history of this business, which originated in two young men from war-torn Europe reaching the decision to become dealers in Australia's iconic gemstone. The shop itself is quite magnificent, ideally located by Circular Quay, so easy to access from a CBD hotel, the ferry or a newly arrived cruise ship. We were looked after by the charming Matthew, who couldn't have been more friendly or patient or knowledgeable, and even kept the shop open for us to make our final decision, one which we have not regretted for a single moment. We also met the lovely owner, Fiona, whose eye for detail clearly makes the business so successful. Dealing with A + C was a pleasure from beginning to end, and the after-sales service so helpful it is obvious they do not view their customer as a number, but rather as someone who shares their passion for the finest opals which, after much research, I discovered you are more likely to find at Altmann + Cherny than anywhere else in Australia.

If you want a quality piece of Australian opal jewelry Altmann + Cherny is the place to shop! Not only are the designs extraordinary, but Fiona is exceedingly knowledgeable and truly cares that you get the perfect piece for you. She spent time to understand my taste and then expertly guided me to the perfect pendant. Their knowledge of the mining process, how to select a quality stone and keen eye for design are impressive. I highly recommend this family owned establishment!

Fiona was so knowledgeable about opals. I had done some research prior to shopping but nothing compares to her. There is nothing like the Lighting Ridge Crystal Black Opal anywhere in the U.S. that I have seen. A wonderful buying experience for my new family heirloom! Thank you!

Working with Fiona was an absolute pleasure and a truly memorable experience. As the owner of an opal jewelry store deeply rooted in Australia’s cultural and historical legacy, she combines unparalleled expertise in opal history and refined jewelry design with a level of professionalism and warmth that is rare. Fiona was exceptionally attentive, respectful, and intuitive in understanding my needs and interests, making the entire process effortless and enjoyable; together, we found exactly what I was looking for and completed the purchase with ease and confidence. Her knowledge, integrity, and discerning eye place her among the leading authorities in opal jewelry not only in Australia but on the global stage. I offer my strongest recommendation for Fiona and her business partners to anyone seeking authentic, exceptional opal jewelry and an experience defined by trust, excellence, and genuine care.

Altmann + Cherny has an amazing selection of beautiful Opal Jewelry. The staff was very welcoming and helpful. They assisted in finding the perfect Opal for me that I will truly treasure. Thank you for your assistance and hospitality. I hope to be back to Sydney and shop in your store again in the future.

Fiona and her team of jewelry and opal experts are great to work with. They are knowledgeable, attentive and patient! I would not buy from any other opal dealer in Australia.
