Light passes through the stone's translucent silica layers and refracts back as shifting multicolour: no single dominant hue, just a quiet, gradient-like movement of colour that reveals something different in every light. \"Soft brightness\" isn't a weakness — it's the character of a stone whose colour glows rather than flashes, the kind of depth that draws you in rather than announcing itself across the room. The pendant is claw\/prong-set in sterling silver, suspended on a rhodium-plated chain at 45 cm — a length that sits at the collarbone, letting the stone lie flat and catch the light all day.\u003c\/p\u003e\n\n\u003ch2\u003eAbout Black Opal\u003c\/h2\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 body tone — the darkness of the stone's base — defines its character: at the darker end, body tone creates dramatic high-contrast flashes; at the lighter end, where this stone sits, the base is translucent and colour appears to glow from within.\u003c\/p\u003e\n\u003cp\u003eCrystal black opal sits in a specific and prized category. Light passes through the silica layers and refracts back as colour, giving the stone a lit-from-within quality that solid dark-body stones can't match. Combined with multicolour play and a substantial 3.17 carats, this is the kind of stone collectors hunt for.\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\u003eCarat Weight:\u003c\/strong\u003e 3.17 ct\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDimensions:\u003c\/strong\u003e 17 × 9 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eColour Play:\u003c\/strong\u003e Multicolour\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 Soft\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSetting:\u003c\/strong\u003e Sterling Silver, claw \/ prong\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChain:\u003c\/strong\u003e Rhodium-plated, 45 cm\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.
