About Us

Our Mission

Thank you for visiting the Opal Gallery website.
Opal Gallery (previously known as Bentine Gems, the world’s largest Opal trading company) has been operating in the Gold Coast, Queensland, Australia since 1985. In 1999, we became independent and became known as Opal Gallery in 2003. We have been an Opal specialist for over 35 years.
With the evolving world of online shopping and digital communication, we believe that it is important that we provide genuine and authentic products rather than enhanced or artificial Opals which are often mistakingly purchased. We are Opal professionals with an extensive knowledge on Opals which we hope to share with you.

We have provided Opals to many VIPs through exhibitions at Australia embassy in Tokyo and other Major Cities in Japan. Also awarded Akiko Wada, a famous singer in Japan, the title of ‘Opal Queen’ together with the Australian Government.

Due to COVID-19, we have started our new online store to enable customers to learn about Opals and purchase products from anywhere in the world. We hope to provide the same high quality customer service and experience as the millions of customers who have previously visited our store through the online platform.
Please immerse yourself in the magic of Opals and enjoy making Australia’s national gemstone as a special treasure, just for you.

Testimonial

My parents and I have been purchasing opal jewellery from Opal Gallery for over 30 years. The staff are very friendly and kind and genuinely care for their customers. They have beautiful jewellery that can be worn daily to luxurious pieces for special occasions. They have helped us numerous times and give us advice and guidance on the tourism side of things when we travel to Australia.

For more than 20 years I have been recommending Opal Gallery for its great service and quality Australia opal jewellery. Friends and their interstate and overseas visitors have all enjoyed buying a lovely piece of Australian Opal or opal jewellery and have often returned to buy more for their friends, family, and / or work colleagues. Opal Gallery also has some excellent ideas for Australian made souvenir jewellery and items, all showcasing genuine Australian opal. The staff are very experienced in opal product and can give terrific information about black opal, white opal and the beautiful boulder opal, whether it be for a jewellery piece or a treasured memento of a visit to the Gold Coast and Australia. They have an online store now but still provide great service and the products all carry the Opal gallery guarantee. I recommend them to anyone looking for something beautifully different as either a personal purchase or as a special gift.

Superb opals from Opal Gallery .. I love each piece I have .. absolutely beautiful... thoroughly recommend Mr Kojima & his staff... such amazing stones.. If you're holdaying on the Gold Coast take the time to check this store out.. you won’t be disappointed ... 10/10
