Boulder Opal Pendant on Gold Chain

Australia's Most Spectacular Gemstone

Nothing in the mineral world compares to the play-of-colour in a Boulder Opal. Flashes of electric blue, green, gold, and red dance across the stone as it catches the light — a phenomenon unique to opal and unlike any other gemstone on Earth. This pendant, set on a gold chain, pairs Australia's most celebrated gemstone with warm, complementary metal for a truly luxurious result.

Details

• Stone: Boulder Opal — natural Australian opal formed within ironstone host rock (matrix), unique to Queensland
• Play-of-colour: Vivid spectral flashes across the stone's surface, shifting with movement and light
• Form: The ironstone backing is retained, giving the stone depth, durability, and a distinctive natural appearance
• Chain: Gold chain
• Each pendant is unique — no two Boulder Opals display the same colours or patterns

About Boulder Opal

Boulder Opal is found almost exclusively in Queensland, Australia, making it one of the rarest and most distinctly Australian gemstones in the world. Unlike white or black opal, Boulder Opal forms in thin seams within ironstone boulders — the host rock is left intact as part of the finished stone, adding structural strength and a beautiful natural contrast to the opal's colour. Australia produces over 95% of the world's precious opal supply.

Care Instructions

Opal contains water and can crack if exposed to extreme temperature changes or prolonged dryness. Avoid ultrasonic cleaners, harsh chemicals, and direct sunlight for extended periods. Clean gently with a soft, damp cloth and store in a padded jewellery box.
