This 30.5ct Australian solid boulder opal pendant is a natural gemstone necklace set in sterling silver.
Sourced from Winton, Queensland, the opal displays vivid blue and green fire shimmering across its rich brown ironstone matrix, giving it a striking, luminous appearance.
Measuring 22 ร 21 ร 7 mm, this polished cabochon is bezel set in S925 stamped sterling silver, ready to wear or gift.
The color play shifts under natural and artificial light, making this pendant a captivating choice for everyday wear or statement jewelry.
Guaranteed 100% natural and untreated, this is a genuine solid opal, not a doublet or triplet.
Its large size and brilliant fire make it highly desirable for jewelry collectors, October birthstone lovers, and anyone seeking a bold opal necklace.
At 30.5 carats, this pendant has both weight and presence, making it suitable for fine jewelry design or as a luxury gift.
Whether for him, for her, or as a unisex jewelry piece, this boulder opal pendant brings the beauty of Australian opals into a wearable form.
Your pendant will arrive gift ready in our signature Opal Galaxy box for a premium unboxing experience.

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.
