This 6.95ct natural solid crystal boulder opal from Queensland displays vibrant purple and blue fire glowing through its translucent honey body. This gemstone combines crystal transparency with a warm honey base tone, creating a rich effect where electric purple and blue colors float within the stone. The contrast between cool fire colors and warm body tone creates appealing depth perfect for contemporary jewelry designs.

Expertly cut and polished into an oval cabochon measuring 20 x 12.1 x 4.3 mm, this natural gemstone offers comfortable proportions perfect for versatile jewelry applications. The translucent quality allows light to pass through, creating brilliance that changes throughout the day. This size works beautifully for sterling silver pendants where the purple blue fire can shine, or set in yellow gold or rose gold to enhance the warm honey tones. The stone also works well for rings designed for occasional wear. Learn how to set crystal opals for best results in your 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 sandstone backing that crystal boulder opals are known for. The purple and blue fire through honey body creates more visual warmth than typical light bodied stones. The 4.3mm depth provides good structure for secure settings in both pendants and rings.

As the official opal October birthstone, this natural gemstone carries symbolic meanings of creativity, passion, and inspiration. The vibrant purple and blue fire through warm honey tones creates an inviting aesthetic perfect for jewelry that balances bold color with approachable warmth. This accessible stone offers eye catching fire at a friendly price point.

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.
