This Coober Pedy crystal opal parcel contains 18 calibrated stones totaling 4.71 carats in two sizes: six 7x5mm and twelve 6x4mm pieces. All stones display electric neon fire with intense orange, yellow, green, cyan, blue, and pink flashes throughout transparent crystal bodies. The neon quality creates brilliant color bursts that remain visible from multiple angles, with exceptional brightness ideal for statement jewelry. This quantity allows for three complete pairs of 7x5mm earrings plus six pairs of 6x4mm earrings, or multiple coordinated sets.

The calibrated dimensions fit standard jewelry mountings, eliminating custom setting costs and streamlining production for professional jewelers. The 7x5mm stones work for statement earrings, pendants, or ring accents, while the 6x4mm stones create delicate studs, cluster designs, or halo accents. Precision sizing ensures seamless finishing in bezel or prong settings across any metal. The mixed shapes provide design flexibility for both traditional and contemporary jewelry styles.

Coober Pedy crystal opals offer excellent transparency and neon fire intensity at accessible wholesale pricing. Large calibrated parcels like this simplify inventory management and coordinated jewelry creation for professional jewelers and designers. The solid structure provides durability for everyday wear while the electric neon fire creates the bold color impact that makes these stones versatile for both statement pieces and delicate designs.

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.
