Our curated collection includes both solid opals and doublet opals, allowing you to find the right opal gem for any jewellery design.
Available Opal Gem Options
Australia is the world’s leading source of high-quality opal gemstones, producing over 90% of the global supply. Each region in Australia offers its own distinct style of opal gem, from the rich ironstone patterns of Queensland to the fiery brilliance of Coober Pedy and the dramatic contrasts of Lightning Ridge. At Johnston Opals, we’re proud to connect you with the finest examples of this iconic national gem.
Our dazzling inventory includes the following opal gemstone options:
- Queensland Boulder Opals – Queensland boulder opals are one of the most unique and prized types of opal gemstone Australia has to offer. These stunning stones form naturally within ironstone boulders, resulting in captivating patterns and rich earthy tones that contrast beautifully with the vibrant opal crystal veins. Each boulder opal is one-of-a-kind, with brilliant flashes of blue, green and red that shimmer as the stone moves.
- Solid Opals – Our collection of solid opals includes natural stones that haven’t been layered or treated, preserving the full integrity and depth of their colour. Solid opal gemstones are perfect for high-end jewellery thanks to their enduring beauty and natural strength. From pastel-hued white opals to rare black varieties, each solid opal stone we offer is a genuine product of nature.
- Doublet & Triplet Opals – For an affordable yet stunning option, consider our doublet and triplet opals. These layered stones feature a thin slice of vibrant opal backed with other materials to enhance durability and showcase the stone’s natural colours. Triplets include a clear cap that magnifies the opal’s brilliance. These types of opal gems are ideal for earrings, pendants and rings, offering a more accessible way to enjoy the beauty of opals.
- Lightning Ridge Black Opals – Renowned worldwide, Lightning Ridge black opals are among the most sought-after and valuable opals. Their dark body tone makes the colour play incredibly vivid, showcasing an intense spectrum of electric blues, greens, reds and purples. Each black opal crystal is a masterpiece of natural art, perfect for heirloom-quality jewellery.
- White Solid Opals – Delicate and luminous, white solid opals offer a softer alternative to their darker counterparts. Known for their milky base tone and flashes of pastel colour, these opals are classic and elegant. Whether set in gold or silver, white opal gemstones are timeless, making them a popular choice for everyday jewellery and special occasions alike.
- Opal Pairs – Perfectly matched opal pairs are ideal for earrings or other symmetrical designs. These pairs are carefully selected to ensure harmony in size, colour and pattern, allowing for beautifully coordinated pieces. Our experts work diligently to find the perfect complements among our collection.
- Opal Stones with Green – Vibrant green is one of the most desired opal colours, symbolising energy, nature and renewal. Our opal stones with green flashes are particularly captivating, often found in boulder opals and black opals. The interplay of green with other hues creates a magical glow that makes each stone feel alive.
- Coober Pedy Solid Fire Opals – Coober Pedy solid fire opals are famous for their dazzling colour and light. These stones typically feature a lighter body tone, allowing their fiery rainbow hues to shine brilliantly. Hailing from South Australia’s most iconic opal mining region, these opal stones are considered some of the most radiant in the world.
- And More – At Johnston Opals, our collection goes far beyond these popular Australian opal stone varieties. We offer a range of opals with rare colour patterns and unique cuts, with something in our collection to spark every imagination.
