This 7.22ct natural solid crystal boulder opal from Queensland displays soft green fire glowing through its translucent crystal body. This gemstone combines crystal opal transparency with boulder opal's natural ironstone backing, creating an ethereal effect where the green color appears to float within the stone. The gentle glow makes this piece perfect for nature inspired jewelry designs.
Expertly cut and polished into an oval cabochon measuring 22.7 x 12.4 x 4.1 mm, this natural gemstone offers generous size perfect for statement pendants or bold rings. The translucent quality allows light to pass through the stone, creating soft depth that changes throughout the day. This size works beautifully for sterling silver pendants or rings where the glowing green can be the focal point, or set in yellow gold or rose gold for a warm, organic look. The stone also pairs well with other natural gemstones for bohemian style jewelry designs.
Completely natural and untreated, this is genuine solid Australian crystal boulder opal, not a doublet or triplet. The authentic Queensland origin guarantees you are receiving a natural gemstone with the characteristic sandstone backing that crystal boulder opals are known for. This type offers good durability thanks to the backing material while maintaining attractive translucent quality. The 4.1mm depth provides solid structure for everyday wear in pendants or occasional wear rings.
As the official October birthstone, this natural gemstone carries symbolic meanings of creativity, passion, and inspiration. The soft green glow creates a peaceful, earthy aesthetic perfect for casual jewelry, nature lovers, and those who appreciate unique gemstones with organic character and affordable beauty.
This natural crystal boulder opal will arrive securely packaged in an Opal Galaxy luxury gift box, ready for professional jewelry setting or safe storage.

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.
