This 32ct natural boulder opal pendant necklace from Koroit, Queensland, displays vibrant blue and green fire scattered throughout its polished brown ironstone matrix. Ready to wear on an adjustable brown cord, this opal necklace features an elongated design with multiple opal pockets creating a flowing pattern down the length of the stone. The distinctive shape measuring 46 x 10 x 5 mm makes this pendant a unique conversation piece perfect for those who appreciate natural gemstone jewelry with character.
Expertly polished to a smooth finish, this natural gemstone showcases the signature Koroit aesthetic where colorful opal pockets contrast beautifully against earthy ironstone. The long, slender proportions create elegant lines that flatter any neckline, while the multiple color pockets ensure visual interest from every angle.
The adjustable cord allows you to customize the necklace length to suit any outfit, making this opal jewelry piece versatile for both casual everyday wear and special occasions.
The drilled hole is professionally finished and secure for safe, comfortable wear.
Completely natural and untreated, this is genuine solid Australian boulder opal, not a doublet or triplet.
The authentic Koroit origin guarantees you are receiving a gemstone with the distinctive scattered opal pattern that makes this Queensland region famous among collectors.
The elongated 46mm shape offers impressive length while remaining lightweight and comfortable. If you prefer a different setting, the pendant can easily be removed from the cord and set in yellow gold, sterling silver, or bronze to complement the warm earth tones and create a custom jewelry piece.
As the official opal October birthstone, this natural gemstone pendant carries symbolic meanings of creativity, passion, and inspiration.
The flowing pattern of blue green fire combined with polished ironstone creates an organic aesthetic that appeals to anyone who loves unique, handcrafted jewelry with authentic Australian character.
This boulder opal pendant necklace will arrive securely packaged in an Opal Galaxy luxury gift box, ready to wear immediately or present as a thoughtful gift.

Caring for Your Australian Opal
Opal Jewelry
Important: Opals Are Fragile Gemstones
Opals are softer than sapphires, rubies, or diamonds and will crack or chip if struck hard against solid surfaces.
Always remove opal jewelry before:
Sports or physical activities
Manual labor, gardening, or gym workouts
Household tasks where impact is possible (lifting, moving furniture, etc.)
Even a minor knock during everyday wear can cause permanent damage. Treat opals as delicate gemstones, not everyday workwear.
Cleaning Your Opal
Clean with warm water and mild soap. Avoid harsh chemicals like bleach, ammonia, or chlorine. Light exposure to hand soap or dishwashing detergent is safe.
Storage
Store opal jewelry separately from harder gemstones (diamonds, sapphires) to prevent scratching.
Solid Natural Opals
(Black, Boulder, Crystal, White Opal)
Natural solid opals are stable and won't change color or crack from water, humidity, or temperature changes. They are safe to submerge in water and can be worn daily, provided they are protected from physical impact. Solid opals are a single piece of gemstone with no artificial backing, making them ideal for heirloom quality jewelry when handled with care.
Opal Doublets
Opal doublets consist of a thin slice of natural opal bonded to a dark backing. Do not submerge doublets in water as prolonged exposure can weaken the adhesive bond and cause separation or cloudiness. Remove doublet jewelry before swimming, bathing, or washing dishes. Clean with a damp cloth only; do not soak or use ultrasonic cleaners.
Like all opals, doublets are fragile and must be protected from impact.
Not sure which type you have? Solid opals show natural color throughout the stone. Doublets have a visible dark backing layer when viewed from the side.
