The opal sits in a clean bezel of 18K white gold, the cooler metal tone a deliberate pairing: white gold steps out of the way and lets the blue do its work, rather than competing with it the way yellow gold sometimes can. One stone, set once, sized to O AU — ready to wear as it is, or resized before it leaves Joseph's workshop.\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\u003eColour Play:\u003c\/strong\u003e Blue dominant, 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 Strong flash\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\u003eMetal:\u003c\/strong\u003e 18K White Gold\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRing Size:\u003c\/strong\u003e O AU ≈ 7½ US ≈ 55 EU\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eResizeable:\u003c\/strong\u003e Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTreatment:\u003c\/strong\u003e Solid natural — untreated\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.

Joseph or his jeweller can take the band up or down by a size or two; larger adjustments may be possible depending on the band's design. Resizing is best done before delivery so the ring arrives ready to wear. Get in touch with your size and we'll quote.\u003c\/div\u003e\u003c\/details\u003e\n\u003cdetails class=\"rotr-faq\"\u003e\u003csummary\u003eWhy white gold instead of yellow?\u003c\/summary\u003e\u003cdiv class=\"rotr-faq-answer\"\u003eMost of Joseph's gold pieces are in 18K yellow gold, so this one is a little different. White gold is 18K gold alloyed with white metals and finished with rhodium plating — it reads silver-cool rather than warm. For a stone with strong blue play, the cooler setting tends to complement rather than fight the colour. If you'd prefer yellow gold, get in touch and Joseph can discuss a custom remake.\u003c\/div\u003e\u003c\/details\u003e\n\u003cdetails class=\"rotr-faq\"\u003e\u003csummary\u003eWhat does semi-dark body tone mean?\u003c\/summary\u003e\u003cdiv class=\"rotr-faq-answer\"\u003eSemi-dark means the background of the stone sits between a light-bodied opal and a fully black one — dark enough to give the colour real contrast and depth, but not so heavy that the stone looks black. In practice it means the blue flash reads clearly without needing bright light to pull it out.\u003c\/div\u003e\u003c\/details\u003e\n\u003cdetails class=\"rotr-faq\"\u003e\u003csummary\u003eIs this a natural Australian opal?\u003c\/summary\u003e\u003cdiv class=\"rotr-faq-answer\"\u003eYes — a solid, untreated boulder opal from Queensland.
