Discover Your Perfect Opal Necklace

An opal necklace is more than just a piece of jewellery—it’s a wearable piece of Australia’s natural heritage and landscape. Formed over millions of years deep beneath the earth, every opal tells a unique geological story through its colours, patterns, and brilliance. No two are the same, making your opal necklace truly one of a kind.

Opals have been prized for centuries for their mesmerising “play-of-colour,” an optical phenomenon where flashes of vivid red, green, blue, and gold seem to dance within the stone. This living fire of colour makes them unlike any other gemstone. From classic white opal pendants to rare and valuable black opal necklaces and striking boulder opal statement pieces, each design offers a distinct personality and allure.

At Black Star Opal, we specialise exclusively in genuine Australian opals—the finest in the world—ethically sourced from outback locations like Lightning Ridge, South Australia and Queensland. Our decades of experience as miners, exporters, and jewellers mean we can offer not only exquisite quality but also exceptional value.

Types of Opal Necklaces in Our Collection

White Opal Necklaces

Originating mainly from Coober Pedy, white opals feature a pale or milky body tone with flashes of soft, pastel hues. They are elegant and versatile, pairing beautifully with both gold and silver settings. These necklaces are perfect for those who prefer subtle, romantic colour play over bold, dramatic tones.

Crystal Opal Necklaces

Crystal opals are celebrated for their transparent to semi-transparent body, allowing the play-of-colour to shine through with extraordinary intensity. Their neon-like brilliance makes them striking when worn directly against the skin, as the body tone adapts to the wearer.

Black Opal Necklaces

Black opals, mined almost exclusively in Lightning Ridge, are the rarest and most valuable of all opal types. Their dark body tone acts as a dramatic backdrop for vivid flashes of colour — often reds, greens, and blues — that seem to glow from within. These opals are often set in gold or platinum and are highly sought after by collectors.

Boulder Opal Necklaces

Sourced from Queensland, boulder opals form naturally within ironstone. This creates unique, earthy patterns where veins or patches of vibrant opal contrast against the dark host rock. Boulder opal necklaces are loved for their rugged natural beauty and individuality.

Doublet & Triplet Opal Necklaces

These are made by combining a thin layer of natural opal with a dark backing (doublet) or a backing and a protective quartz or glass cap (triplet). They offer vibrant colour at a more affordable price point, making them a great option for first-time opal buyers.

How to Choose the Perfect Opal Necklace

1. Understand Play-of-Colour
Opals display an ever-changing spectrum of colour when moved under light. Look for stones with vivid, saturated colours visible from multiple angles.

2. Explore Patterns
From the rare Harlequin pattern to Pinfire, Flagstone, and Rolling Flash, each pattern offers a different visual effect. Some buyers are drawn to precise, geometric arrangements, while others prefer freeform flashes.

3. Consider Body Tone
The base tone of an opal — whether white, light, crystal, or dark — greatly influences how its colours appear. Darker tones often make colours look more vivid.

4. Check Brightness
Brightness measures how strongly the colours in the opal stand out. The brighter the stone, the more valuable and visually striking it tends to be.

5. Choose a Setting
Claw settings maximise light entry for sparkle, while bezel settings offer a sleek look and protect the edges of the stone — a great choice for daily wear.

6. Pick Your Metal
Yellow gold enhances warm reds and oranges, white gold complements cooler blues and greens, and sterling silver offers a modern, affordable finish.

7. Match to Your Lifestyle
If you plan to wear your opal necklace daily, opt for a design with a secure setting and a stone with good durability. For special occasions, you might choose a more intricate or statement style.
