Sourced from a retired jeweller’s collection and dating to approximately the 1970s, this is a striking statement gemstone with both presence and provenance.\u003c\/p\u003e\n\u003cp\u003eCut in a classic emerald form, the stone displays broad, open facets that emphasise its excellent clarity and create a calm, glass-like brilliance. Unlike smaller, highly sparkly stones, this piece offers a more sophisticated, architectural beauty—highly prized in bespoke jewellery design.\u003c\/p\u003e\n\u003cp\u003eThe colour is a beautifully balanced medium London blue, sitting between deep inky tones and brighter Swiss blues. This softer denim hue is particularly versatile, working seamlessly in both yellow and white metal settings.\u003c\/p\u003e\n\u003cp\u003eWeighing an impressive 72.92 carats, this gemstone is far larger than typically encountered in finished jewellery and is ideally suited for a bold custom ring, pendant, or collector’s piece. Stones of this scale are rarely seen outside of specialist jeweller inventories.\u003c\/p\u003e\n\u003cp\u003eTested using a Presidium Gem Tester and confirmed as topaz. A rare opportunity to acquire a gemstone of this scale at a fraction of the cost of comparable custom-cut stones.\u003cbr\u003eMEASUREMENTS\u003cbr\u003eWeight: 72.92 carats\u003cbr\u003eDimensions: 25.95mm x 18.29mm\u003cbr\u003eDepth: 13.10mm\u003cbr\u003eCONDITION\u003cbr\u003eInternally clean and in very, very good condition.\u003cbr\u003eUnder close magnification, there are a few tiny nibbles to the facet edges—minor and entirely consistent with age and scale, with no impact on beauty or structural integrity.\u003cbr\u003e____________________________\u003cbr\u003eADDITIONAL INFORMATION\u003cbr\u003e* Free worldwide shipping on all purchases\u003cbr\u003e* Returns - you can return your item for a refund for any reason.
