This Coober Pedy crystal opal pair features 2 precisely calibrated pear-shaped stones totaling 1.34 carats. The graduated sizing includes one 10x7mm stone and one 8x5mm stone, both displaying vibrant multicolor fire with green, yellow, orange, and blue flashes throughout translucent crystal bodies. The graduated proportions create elegant visual flow perfect for modern drop earrings or asymmetric designs, while the matched fire pattern ensures cohesive pairing.
The calibrated dimensions eliminate custom setting costs and fit standard jewelry mountings perfectly. The larger 10x7mm stone works beautifully as a pendant focal point while the smaller 8x5mm creates a matching earring, or both stones can be used together for graduated drop earrings following contemporary design trends. The precision calibration ensures professional finishing in bezel or prong settings across sterling silver, gold, or platinum mountings.
Coober Pedy crystal opals are prized for their transparency and vibrant rainbow fire quality. Calibrated graduated pairs like this, where both stones display consistent multicolor saturation despite size difference, represent premium material for professional jewelers creating sophisticated, modern designs. The transparent crystal structure provides durability while the intense fire creates visual impact that makes Coober Pedy material valued for contemporary jewelry.
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.
