The dominant colour is green, vivid and strong, with blue moving through it as the stone shifts in light. The setting is a bezel in 18K yellow gold, finished with white gold detailing and small diamond accents that frame the opal without competing with it — the two-tone metalwork draws the eye toward the stone rather than away from it. Cut to AU size L, ready to wear or resize to suit.\u003c\/p\u003e\n\n\u003ch3\u003eAbout Black Opal\u003c\/h3\u003e\n\u003cp\u003eBlack opal is the rarest and most sought-after variety of Australian opal, mined almost exclusively from Lightning Ridge in New South Wales. Its dark body tone — from dark grey to jet black — creates a dramatic backdrop that intensifies the stone's natural play-of-colour, producing vivid flashes that appear to glow from within. Black opal with strong fire is particularly prized by collectors and is considered among the most valuable gemstones in the world.\u003c\/p\u003e\n\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStone:\u003c\/strong\u003e Black Opal\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eColour Play:\u003c\/strong\u003e Vivid green dominant with blue secondary — multicolour, strong and bright\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 — vivid, bright fire\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSetting:\u003c\/strong\u003e Bezel — 18K yellow gold with white gold detailing and diamond accents\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAccent Stones:\u003c\/strong\u003e Small diamonds (count not specified)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMetal:\u003c\/strong\u003e 18K Yellow Gold with white gold detail\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRing Size:\u003c\/strong\u003e AU L \/ US 6 \/ EU 51\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eResizeable:\u003c\/strong\u003e Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOrigin:\u003c\/strong\u003e Lightning Ridge, New South Wales, 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.

In practical terms: the green and blue colour play has a strong, vivid backdrop, and the stone catches the light without looking opaque or flat.\u003c\/div\u003e\u003c\/details\u003e\n\n\u003cdetails class=\"rotr-faq\"\u003e\u003csummary\u003eWhat is the two-tone metal in this ring?\u003c\/summary\u003e\u003cdiv class=\"rotr-faq-answer\"\u003eThe ring is set in 18K yellow gold with white gold detailing — two alloys of gold used in the same piece. The warm yellow of the band complements the opal's green and blue tones, while the cooler white gold detail and diamond accents add definition to the setting without introducing a different metal into the piece.\u003c\/div\u003e\u003c\/details\u003e\n\n\u003cdetails class=\"rotr-faq\"\u003e\u003csummary\u003eCan the ring be resized?\u003c\/summary\u003e\u003cdiv class=\"rotr-faq-answer\"\u003eYes — this ring can be resized. 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.
