Each stone in the pair is bezel-set in 18K yellow gold, with small bezel-set diamonds framing the opal's edge. At 3.28ct total, the stones sit with quiet weight on the ear: not oversized, not delicate — present. The semi-dark body gives the colour real contrast without the stone reading heavy. Queensland boulder opal, solid and natural, nothing added.\u003c\/p\u003e\n\n\u003ch3\u003eAbout Boulder Opal\u003c\/h3\u003e\n\u003cp\u003eBoulder opal forms as veins of precious opal within ironstone matrix in the opal fields of Queensland — primarily Quilpie, Yowah and Winton. Unlike black opal from Lightning Ridge, the opal cannot be separated from its host rock; it's cut as a single solid piece, with the natural brown ironstone remaining as the stone's backing. This gives boulder opal its distinctive look — vivid colour against rich earth tones — and also makes it physically more durable than other opals, since the ironstone host is harder than the opal layer it carries.\u003c\/p\u003e\n\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStone:\u003c\/strong\u003e Boulder Opal\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTotal Carat Weight (TCW):\u003c\/strong\u003e 3.28ct (pair)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eColour Play:\u003c\/strong\u003e Green\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 Strong colour\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSetting:\u003c\/strong\u003e Bezel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAccent Stones:\u003c\/strong\u003e Small bezel-set diamonds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMetal:\u003c\/strong\u003e 18K yellow gold\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eClosure Type:\u003c\/strong\u003e Stud — post-and-butterfly\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOrigin:\u003c\/strong\u003e Queensland, Australia\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTreatment:\u003c\/strong\u003e Solid natural — untreated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAvailability:\u003c\/strong\u003e One-of-a-kind — 1 pair 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, so a little care goes a long way.

It's dark enough to give the colour real contrast — so greens and blues read with depth — but warm rather than heavy. Boulder opal with a semi-dark body tends to photograph beautifully because the ironstone backing and the opal tone work in the same earthy register.\u003c\/div\u003e\u003c\/details\u003e\n\u003cdetails class=\"rotr-faq\"\u003e\u003csummary\u003eHow are these worn?\u003c\/summary\u003e\u003cdiv class=\"rotr-faq-answer\"\u003eThese are stud-style earrings — pass the post through a pierced ear, and the butterfly back clips into place behind the lobe to hold them securely.
