This crystal boulder opal from Queensland showcases a dramatic display of vibrant pink and purple fire dancing across a translucent blue body. The elongated triangular shape creates a striking canvas for the opal's natural color play, with concentrated bursts of bright magenta and violet contrasting beautifully against the cooler blue tones. The stone's transparency allows light to penetrate and illuminate the fire from within, producing a luminous effect that shifts and transforms with movement.

At 17.3 x 6.7 x 3 mm and weighing 1.95 carats, this distinctive triangular crystal boulder opal offers an eye catching silhouette ideal for pendant necklaces or unique ring designs. The slim profile and elongated proportions create an elegant, modern aesthetic that works particularly well in contemporary jewelry settings. This opal pairs beautifully with custom jewelry settings in sterling silver for casual wear, or can be showcased in gold for a more refined presentation.

This completely natural and untreated solid opal retains its authentic ironstone backing, which provides structural support while displaying the true character of Australian crystal boulder opal. Not a doublet or triplet, this genuine Queensland gemstone features the bold color saturation and transparency that make crystal boulder opals so appealing to jewelry designers seeking distinctive stones at accessible price points. The vibrant pink and purple tones offer more visual impact than typical pastel crystal opals.

As the official opal October birthstone, this gemstone represents hope, creativity, and inspiration. The unusual triangular shape and bold color palette make this crystal boulder opal perfect for those seeking a unique, conversation starting piece. Its striking appearance and friendly pricing offer excellent value for collectors or jewelry makers looking for authentic Australian opal with genuine character.

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.
