This spectacular boulder opal from Queensland displays an explosion of golden orange, yellow, green, and blue fire that covers the entire surface in a dazzling multicolor display. The warm golden and orange tones mix with bright greens and electric blues, creating a painterly effect that looks like fireworks frozen in stone. The dark body tone makes all these colors really pop and glow with incredible intensity.
At 21 x 12.1 x 4.7 mm and weighing 10.17 carats, this boulder opal has substantial size and presence perfect for statement jewelry. The freeform teardrop shape follows the natural contours of how the opal formed, giving it organic character while still being refined enough for high end settings. With this much vivid multicolor fire and impressive size, this stone would make an incredible centerpiece for a pendant or bold ring. The combination of warm and cool tones means it would pair beautifully with gold, platinum, or even mixed metals.
This is completely natural solid boulder opal with no treatment, straight from the Queensland opal fields. Not a doublet or triplet, just authentic Australian boulder opal exactly as it formed. The full spectrum of fire colors from warm golds and oranges through to cool greens and blues makes this stone particularly special and versatile. Boulder opals with this much color coverage and intensity are becoming increasingly rare as the best deposits are mined out.
As the official opal October birthstone, this stone represents hope and creativity. The spectacular multicolor fire and substantial 10 carat size make it perfect for serious collectors or as an investment piece in fine jewelry. This boulder opal offers museum quality color and size at competitive pricing.
This 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.
