The dark body pulls the flash of colour forward, so the play-of-colour reads clearly even in ordinary light. Set in a sterling silver bezel that keeps the stone the whole story, and hung on a rhodium-plated chain that resists tarnish. Queensland boulder opal at this size with a dark body is a piece you wear rather than tuck away.\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\u003eDimensions:\u003c\/strong\u003e 25×13mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Tone:\u003c\/strong\u003e 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\u003eSetting:\u003c\/strong\u003e Bezel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChain:\u003c\/strong\u003e Rhodium-plated sterling silver, 45cm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOrigin:\u003c\/strong\u003e Queensland, 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, so a little care goes a long way.

A dark body gives the colour real contrast — it works like a black backdrop in photography, making the flash of colour appear sharper and more vivid than it would against a light background. On this stone the dark ironstone host provides that backdrop naturally, which is part of what makes boulder opal distinctive.\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.
