This 187 carat natural boulder opal pendant from Winton, Queensland displays vivid blue and green fire flowing through preserved wood fossil structure. The luminous color appears in striking veins and cracks across the brown ironstone matrix, creating dramatic contrast between brilliant fire and natural earthy backing. The wood fossil grain patterns remain visible throughout the stone, adding distinctive organic character. Winton boulder opals form in ironstone and ancient wood where precious opal fills natural fractures, creating authentic Australian gemstones with substantial presence and unique appeal.
Measuring approximately 68 × 35 × 11 millimeters, this boulder opal pendant arrives ready to wear on a genuine Greek leather adjustable necklace. The large geometric freeform shape provides impressive statement presence perfect for casual everyday wear or bohemian jewelry style. The adjustable leather cord allows customized length to suit any neckline or personal preference. The substantial size creates bold visual impact while remaining comfortable for daily use. For those who prefer permanent settings, this pendant can be professionally reset into yellow gold, white gold, rose gold, sterling silver, 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 and stability. The ironstone backing provides foundation for the precious opal veins that display fire throughout the stone in organic patterns following natural fracture lines.
Boulder opal pendants like this piece represent quality Australian gemstones with earthy appeal at accessible price points. 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 substantial size, vivid fire, and wood fossil character make this an excellent choice for collectors or anyone seeking distinctive statement jewelry with good value craftsmanship. 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.
