This 25 carat natural wood fossil boulder opal pendant from Winton, Queensland displays vivid blue, purple, and green fire scattered throughout preserved ironstone structure. The luminous color appears in multiple patches across the brown matrix, creating contrast between vibrant fire and natural earthy backing. The compact size concentrates the color play into an accessible format. Winton boulder opals form in ancient wood and ironstone where precious opal fills natural cavities, creating authentic Australian gemstones with distinctive character.
Measuring approximately 25 × 18 × 5 millimeters, this boulder opal pendant arrives ready to wear on a brown adjustable cord necklace. The polished rounded teardrop shape provides comfortable proportions perfect for everyday casual wear and bohemian jewelry style. The adjustable cord allows customized length to suit any neckline or personal preference. The compact size makes this piece ideal for daily use and layering with other necklaces without feeling heavy. For those who prefer permanent settings, this pendant can be professionally reset into sterling silver, yellow gold, rose gold, or bronze designs.
This is a 100% natural, untreated solid boulder opal, not a doublet or triplet. The opal and wood fossil ironstone formed together millions of years ago in the Queensland opal fields, ensuring authentic Australian origin with natural durability. The ironstone backing provides stability and foundation for the precious opal sections that display multicolor fire across the surface.
Boulder opal pendants like this piece represent quality Australian gemstones at accessible price points with good value craftsmanship. As the official opal October birthstone, this pendant offers October born individuals a meaningful gift that celebrates their birth month with authentic natural beauty. The earthy appeal, vivid multicolor fire, and compact size make this an excellent choice for collectors or anyone seeking versatile statement jewelry with natural character. This boulder opal pendant necklace will arrive securely packaged in an Opal Galaxy luxury gift box, ready to wear immediately.

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.
