All unset solid opals come directly from Australia’s world-famous opal fields renowned for producing beautiful, high-quality natural opals, including Lightning Ridge and White Cliffs in outback NSW; Coober Pedy and Mintabie in South Australia; and Winton in Queensland.

Black Star Opal has long-term relationships with many opal miners as well as jewellery manufacturers, suppliers and skilled jewellery designers, both in Australia and around the world

Our jewellers either handcraft or we hand select our jewellery pieces, ensuring only the best quality, and most affordable, items are available from our online store, as well as our retail store The Opal Centre, located at The Big Banana in Coffs Harbour.

Like all gemstones, the value of an opal depends on several factors including the type of opal (solid, doublet, triplet, black, white, crystal, boulder, etc), body tone, brilliance, pattern, colour bar thickness, and play of colour.

Other key factors that affect an opal's price are the size (carat weight), cut and polish of the stone. For more information about how opals are valued, please read our article The Value of Australian Opal.

Black Star Opal only sells 100% natural, ethically sourced Australian opals and opal jewellery, and we guarantee our collection for authenticity and quality. 

In addition to solid opals, we sell doublet and triplet opals, which are opal composites that feature natural opal as the main component. Doublet and triplet opals are sold throughout the world, mainly as an affordable alternative to natural black opal, retaining the beauty of this precious gemstone without the higher price often associated with the rare and precious black opal.

Black Star Opal does not sell synthetic opal, which contains no natural opal and is man-made and created in a laboratory. 

We also retail all our products via our retail store The Opal Centre, which is located at the Big Banana in Coffs Harbour. Our retail store has been operating for over 35 years, and we have been involved in the Australian opal industry for more than 50 years.

Upon request, we are able to provide a Certificate of Authenticity for unset solid opals and opal jewellery, which provides a detailed description and value of your purchase for insurance purposes.

We are also a proud supporter of the Australian Opal Centre ,as an AOC Founder, which is dedicated to showcasing rare opalised fossils and Australian opal.

We always try to capture the most accurate photographic representation of the colours and patterns of the opal gemstone or opal jewellery you are purchasing. However, you may be pleasantly surprised when receiving your purchase that the opal may showcase a broader colour palette and brighter pattern than you thought!

Please note: As we have multiple items in stock, some opal jewellery images are representative of the item's style and design only. Opals in these products may differ slightly in colour or pattern.

All opal pendants come with the gold plated or silver plated display chain pictured.

All rings sold through Black Star Opal are sized according to Australian and USA jewellery standards. To determine your correct ring size, we advise you print and refer to our convenient ring sizing guide and international conversion chart before placing your order.

Where possible, Black Star Opal is able to resize most 9K, 14K and 18K gold opal rings. Just let us know upon purchase if resizing is required and we will let you know if it’s possible.

Silver or gold-plated silver rings cannot be resized. However, if you find a design you like but the correct ring size is not available, please contact us and we will do our best to source one for you.

Treat opal as you would any other precious gem. When handled with care and cleaned in the correct way, your opal will last throughout time. To clean opal, simply wipe lightly with a damp soft cloth and mild detergent. Take extra care not to immerse doublet and triplet opals in water for extended periods of time.

Also, we strongly advise avoiding bleach, chemicals and harsh cleaners, including ultrasonic cleaners, and recommend removing your opal jewellery before using pools or spas.
