Boulder Opal Chips

This 650 gram parcel of boulder opal chips and offcuts comes from the Winton opal fields in Queensland, Australia. This tray is loaded with rough pieces in a range of small to medium sizes, offering strong volume for jewelers, mosaic artists, and hobbyists who need a steady supply of boulder opal material.

The tray shows the classic golden brown and honey toned ironstone that Winton is known for, with natural banding and swirl patterns running across many of the pieces. Color is scattered throughout the parcel, with flashes of blue, green, and purple visible on numerous chips against the warm ironstone background. As offcuts and chips, these pieces vary in shape and thickness, giving buyers a genuine mixed bag of rough material to sort through.

Sizes range from small chip pieces through to medium sized offcuts, making this parcel suitable for inlay projects, wire wrapping, small cabochon cutting, resin casting, or as bulk material for creative and educational lapidary use. At 650 grams, this is a substantial supply for ongoing projects.

All pieces are 100% natural and completely untreated. These are not doublets or triplets. Photographs were taken wet under LED lighting. Dry appearance will differ. Price includes worldwide registered shipping.

This collection will arrive securely packaged in an Opal Galaxy gift box, making it ready for safe storage, jewelry setting, or presentation as a collector gemstone.

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.
