This 50.5 carat natural Wood Fossil boulder opal pendant from Winton, Queensland displays vivid blue and green fire within preserved wood fossil structure. The color appears in concentrated patches across the stone, creating contrast between luminous fire and natural brown ironstone matrix. The wood fossil pattern shows distinctive cellular structure where ancient timber was replaced by opal. Winton boulder opals form in ironstone and wood fossil, giving each piece unique character with earthy appeal and authentic Australian origin.
Measuring approximately 45 × 33.5 × 4.5 millimeters, this boulder opal pendant arrives ready to wear on a brown adjustable cord necklace. The polished hexagonal shape provides substantial presence while remaining comfortable for everyday casual wear. The adjustable cord allows customized length to suit any neckline or personal style. This versatile pendant works well with bohemian fashion or can be professionally reset into yellow gold, white gold, rose gold, sterling silver, or bronze for permanent metal settings.
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 structure and durability. The ironstone backing provides natural stability, with the preserved wood fossil matrix serving as foundation for the precious opal sections that display 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 fire, and hexagonal shape make this an excellent choice for collectors or anyone seeking distinctive statement jewelry with natural character.

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.
