This crystal boulder opal from Queensland shows soft blue and bright green fire moving across its translucent body. The colors have a gentle, watercolor quality with aqua and turquoise blending into lavender and peach tones that shift as you turn the stone. The smooth oval cabochon shape is polished to a high shine, letting light pass through and bringing out that glassy, luminous quality crystal opals are known for.

Measuring 11.7 x 7.5 x 2.8 mm and weighing 1.47 carats, this oval crystal opal has classic proportions that work beautifully for rings, where the shape sits nicely on a finger, or for pendants and earrings. The moderate size makes it versatile for different styles, from delicate everyday pieces to more substantial designs. It would look great in custom jewelry settings with sterling silver for casual wear, or you could pair it with gold for a more refined look.

This is completely natural solid opal with no treatment, keeping its ironstone backing for stability. Not a doublet or triplet, just authentic crystal boulder opal from Australia. The soft blue and green palette gives it a cool, calming presence that's easy to wear with everything. The translucent quality means you can see depth in the stone, which makes the fire more interesting than opaque opals where the color just sits on top.

As the official opal October birthstone, this stone represents hope and creativity. The soothing colors and classic oval shape make it perfect for traditional jewelry settings or meaningful birthday gifts. For anyone wanting authentic Australian opal with gentle color and a timeless shape, this crystal boulder offers quality at a friendly price.

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.
