This crystal boulder opal from Queensland shows concentrated brilliant green fire radiating through its purple tinted translucent body. The center features an intense burst of emerald and lime green that seems to glow from within, while flashes of blue and pink travel across the edges. The colors are bright and saturated, creating a lively play that changes as you turn the stone in the light.
Measuring 13.8 x 8.4 x 4.7 mm and weighing 3.83 carats, this oval crystal boulder opal has a substantial feel with good depth. The classic oval shape is always popular and works beautifully for rings, pendants, or earrings where you want something that catches the eye. This pipe opal formation gives it extra translucency and brightness compared to typical crystal boulder opals. It would look fantastic in custom jewelry settings with sterling silver for everyday pieces, or gold for something more upscale.
This is completely natural solid opal with no treatment, keeping its ironstone backing for stability. Not a doublet or triplet, just genuine Queensland crystal boulder opal formed naturally in pipe deposits. The bright green fire against the purple body creates really nice contrast, and the concentrated color in the center makes it more visually striking than opals with scattered fire. The 4.7mm depth helps the colors really pop when light passes through.
As the official opal October birthstone, this stone carries meaning around hope and creativity. The vibrant green and purple combination gives it an energetic, eye catching presence that works well for statement jewelry or special gifts. For anyone looking for authentic Australian opal with bold color and good size, this crystal boulder delivers quality at a friendly price point.
This 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.
