The stone sits in a clean bezel setting — the silver rim holding the opal flush and secure — and from that 7×5mm face you get a play of green with blue moving through it at medium brightness. Set on a rhodium-plated chain, the silver stays clean longer than uncoated silver would. The overall piece is understated in scale and honest in price — a genuine Australian opal, worn every day, without the premium of a solid stone.\u003c\/p\u003e\n\n\u003ch3\u003eAbout Opal Doublet\u003c\/h3\u003e\n\u003cp\u003eAn opal doublet is a thin slice of natural Australian opal cemented to a dark backing — usually ironstone or black potch (the common opal that doesn't carry colour play). Doublets are a legitimate technique used in the opal trade for over a century: solid opal thick enough to cut as a whole stone is rare, so using the precious opal layer efficiently means more people can own genuine Australian opal at a sensible price. The opal itself is the same material you'd find in a solid stone — just used more efficiently — and the dark backing intensifies the colour play above it.\u003c\/p\u003e\n\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStone:\u003c\/strong\u003e Australian Opal Doublet\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDimensions:\u003c\/strong\u003e 7×5mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eColour Play:\u003c\/strong\u003e Green dominant, blue secondary\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrightness:\u003c\/strong\u003e Medium\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTreatment:\u003c\/strong\u003e Doublet\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSetting:\u003c\/strong\u003e Bezel, sterling silver\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChain:\u003c\/strong\u003e Rhodium-plated, 45cm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOrigin:\u003c\/strong\u003e Australia\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAvailability:\u003c\/strong\u003e One-of-a-kind — 1 piece available\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eCaring for Your Opal\u003c\/h3\u003e\n\u003cp\u003eOpal is softer than diamond or sapphire, and doublets need extra care around water — prolonged exposure can degrade the bond between the opal layer and its backing.

It's been crafted as a doublet, meaning the opal is cemented to a dark backing rather than left as a thicker solid stone. The opal itself is 100% natural and Australian.\u003c\/div\u003e\u003c\/details\u003e\n\u003cdetails class=\"rotr-faq\"\u003e\u003csummary\u003eIs the chain sterling silver?\u003c\/summary\u003e\u003cdiv class=\"rotr-faq-answer\"\u003eThe pendant setting is sterling silver.
