This Coober Pedy crystal opal parcel contains 4 precisely calibrated pear-shaped stones totaling 2.76 carats. The mixed sizing includes two 10x7mm stones and two 8x5mm stones, all displaying vivid multicolor fire with dominant red and pink flashes accented by orange, yellow, green, blue, and cyan throughout transparent crystal bodies. The paired configuration offers perfect options for two matching earring sets or coordinated jewelry pieces, while the consistent fire pattern ensures visual harmony across all stones.

The calibrated dimensions eliminate custom setting costs and fit standard jewelry mountings perfectly. The 10x7mm pair works beautifully for statement drop earrings or larger studs, while the 8x5mm pair creates delicate everyday earrings or accent stones. The precision calibration ensures professional finishing in bezel or prong settings across sterling silver, gold, or platinum mountings. The transparent crystal bodies allow maximum light interaction, creating bright sparkling effects ideal for eye-catching jewelry designs.

Coober Pedy crystal opals are prized for their transparency and vibrant fire quality. Calibrated parcels like this, where all stones display consistent multicolor saturation in matched pairs, represent premium material for professional jewelers creating coordinated collections. The solid crystal structure provides durability while the bright red-dominant fire creates striking visual impact that makes crystal opals valued for statement jewelry pieces.

Authenticity: Natural solid crystal opal. Not treated, not synthetic. Authenticated by Yuka Hatano & Michael Shepherd, IGS Pro Members.

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.
