At the centre of this floral brooch sits a cabochon emerald of substantial scale — 39.11 carats — surrounded by a carefully composed arrangement of marquise-shaped, brilliant-cut and calibré-cut diamonds, all mounted in a combination of platinum and 18 karat white gold. The cabochon cut chosen for a stone this size is a deliberate and traditional decision: rather than faceting away material to maximise brilliance, the smooth domed surface preserves weight and lets the emerald's colour and internal character read with unusual depth, a treatment reserved historically for the finest and most substantial emerald material.
Colour and clarity grading for the centre stone, along with total diamond weight, are available on request. The use of calibré-cut diamonds — small stones custom-cut to fit precisely around the curve of the emerald and the floral outline — is itself a mark of serious workshop investment, since calibré cutting requires each stone to be individually shaped rather than selected from standard inventory. Combined with marquise and brilliant accents providing the floral structure beyond the centre stone, the overall composition demonstrates a level of technical ambition well above a typical estate floral brooch.
A 39.11-carat cabochon emerald of this quality is, in practical terms, an anchor stone for a serious collection — material of this size and character becomes progressively harder to source as fine emerald deposits are depleted, and cabochon-cut stones of this scale in particular rarely appear on the market with the clean colour this piece displays. Collectors motivated by long-term value alongside wearability will recognise this as exactly the category of acquisition that tends to hold and grow in worth over time.
On the body, the floral design and generous scale suit formal evening wear especially well — the shoulder of a structured gown, the lapel of a formal coat, or the centre of an evening wrap, where the emerald's smooth cabochon surface catches and holds light rather than scattering it the way faceted stones do. The platinum and white gold mount has been constructed to carry the stone's substantial weight securely, and the pin fitting has been checked for stability prior to listing.
Independent certification for the emerald is available on request, and given the scale of this stone we recommend it as a matter of course for any serious buyer. This brooch has been entered into the Legacy house register among our significant emerald holdings, reflecting both the rarity of the centre stone and the quality of its execution.
Our advisors welcome a confidential conversation to discuss provenance, condition, and acquisition terms, and we are pleased to arrange a private viewing at your convenience.
