The swirling shapes are rare for a brooch of this construction. The diamond work is exceptional: 81 rose cuts totalling 2.11ctw, plus three old mine cuts including a central stone that runs nearly 5mm deep — almost as deep as it is wide — giving it the true weight of a near-carat stone despite appearing more demure at 5.12mm in width. The total comes to 3.4ctw. The brooch has been tastefully upgraded with a double chain fitting at the top crescent, and a solder repair on the reverse where a screw fitting was once removed — both entirely appropriate to a piece of this age and quality. A possible collection accession number (7045) is visible on the lower left swirl, suggesting a previous institutional provenance. Two eagle head assays confirm 18ct; a further hallmark appears on the silver.\u003c\/p\u003e\n\n\u003chr\u003e\n\u003ch3\u003eDetails\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEra:\u003c\/strong\u003e Art Nouveau, French, c. 1890\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterials:\u003c\/strong\u003e Sterling silver, 18ct pink gold\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStones:\u003c\/strong\u003e 3.4ctw total | 81 rose cuts 2.11ctw + central old mine .93ct est. + .16ct + .20ct old mines\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCentre Stone:\u003c\/strong\u003e Old mine cut, est. .93ct | 5.12mm wide × ~5mm deep\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDimensions:\u003c\/strong\u003e 2.1\"\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 19.16g\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHallmarks:\u003c\/strong\u003e Two eagle head assays (18ct) on pin back; additional eagle head on silver; possible accession number 7045 on lower swirl\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCondition:\u003c\/strong\u003e Excellent historical condition; solder repair on reverse (screw fitting removed); double chain fitting added at top.
