The dark host rock — known as black potch or steel — gives the precious opal layer its signature dark backdrop, which makes colours appear more vivid and saturated than in lighter-bodied stones. A strong green or red flash on a dark body tone is among the most valuable colour combinations in opal.\u003c\/p\u003e\n\n\u003ch2\u003eCrystal vs Dark Body Tone\u003c\/h2\u003e\n\u003cp\u003eWithin the black opal range, body tone is graded N1 (jet black) through N9 (crystal clear). Dark-body stones produce sharp, dramatic flashes; crystal black opals are translucent, with colour glowing from within rather than off the surface. Both are valued — they're different expressions of the same gem, and collectors prize each for different reasons.\u003c\/p\u003e\n\n\u003ch2\u003eHand-Sourced by Joseph\u003c\/h2\u003e\n\u003cp\u003eEvery black opal here is personally hand-selected by Joseph Bernecki — Polish-born, Australian-raised, and a 30+ year veteran of the Australian opal trade.

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\u003cp\u003eCrystal and light-body black opals sit at the lighter end of the body-tone scale. Their base is translucent rather than opaque, so colour appears to glow from inside the stone rather than flashing off a dark background. This gives them a softer, more ethereal quality — different from a dark-body stone, but prized by collectors for exactly that reason. Both ends of the scale are valued; the stone's brightness and pattern quality matter more than body tone alone.\u003c\/p\u003e\n\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStone:\u003c\/strong\u003e Solid Australian Black Opal (natural, untreated)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eColour Play:\u003c\/strong\u003e Mixed flash\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Tone:\u003c\/strong\u003e Crystal\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrightness:\u003c\/strong\u003e Bright\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePattern:\u003c\/strong\u003e Mixed\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSetting:\u003c\/strong\u003e Claw\/prong, 18K yellow gold\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish:\u003c\/strong\u003e Polished\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChain:\u003c\/strong\u003e 18K yellow gold-plated, 45cm\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\u003ch2\u003eCaring for Your Opal\u003c\/h2\u003e\n\u003cp\u003eOpals are softer than diamonds or sapphires, so a little care keeps yours brilliant for generations.\u003c\/p\u003e\n\u003cp\u003eSee \u003ca href=\"\/pages\/opal-care\"\u003eOpal Care\u003c\/a\u003e for storage, cleaning, and what to avoid.\u003c\/p\u003e\n\n\u003ch2\u003eProvenance\u003c\/h2\u003e\n\u003cp\u003eHand-selected by Joseph Bernecki, sourced direct from the Australian opal fields and set in his Sydney workshop.

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.
