The blue flash sits against a semi-dark body that gives the colour genuine contrast: not flat, not too heavy, just dark enough to make the blue read with depth. In motion — turning the head, a shift in light — the flash travels across the stone. In silver, the cool metal keeps pace with the blue rather than competing. Bezel-set at the top, they hang clean and straight. One pair, no two stones like them.\u003c\/p\u003e\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\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eStone:\u003c\/strong\u003e Opal Doublet (natural Australian opal)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDimensions per stone:\u003c\/strong\u003e 31×8mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColour Play:\u003c\/strong\u003e Blue flash of colour\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody Tone:\u003c\/strong\u003e Semi-dark\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrightness:\u003c\/strong\u003e Medium\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePattern:\u003c\/strong\u003e Flash of colour\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\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMetal:\u003c\/strong\u003e Sterling Silver\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClosure Type:\u003c\/strong\u003e French wires\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAvailability:\u003c\/strong\u003e One-of-a-kind pair\u003c\/li\u003e\n\u003c\/ul\u003e\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\n\u003c\/details\u003e\n\u003cdetails class=\"rotr-faq\"\u003e\n\u003csummary\u003eHow are these worn?\u003c\/summary\u003e\n\u003cdiv class=\"rotr-faq-answer\"\u003eThese earrings have French wires — they pass through pierced ears and rest naturally against the lobe, with the stone hanging freely below.
