Exceptional Diamond Brooch Pear Brilliant-cut Diamonds of 8.69, 7.02, 6.21, 5.50, 5.31, 4.07, 4.03, 4.02, 3.64, 3.60, 3

Very few brooches in private circulation carry the kind of graduated diamond architecture found in this piece — fifteen pear brilliant-cut diamonds, ranging from 8.69 carats down to 2.38 carats, set together in a single platinum mounting. The graduation itself is the design: each stone steps down in scale from the next, from 8.69, 7.02, 6.21, 5.50 and 5.31 carats through the mid-range stones to a run finishing at 3.60, 3.60, 3.58, 3.19, 3.01 and 2.38 carats. Assembling fifteen pear brilliants of this size and consistent cut quality in one piece is an undertaking most workshops never attempt.

Colour and clarity grading across the full stone set is available on request; the combined weight of the diamonds alone — well in excess of sixty carats before accounting for accent stones — places this brooch among the most significant diamond pieces our house has offered. The platinum mounting is built purely in service of the stones, with minimal ornamentation beyond what is structurally necessary to hold fifteen large pear brilliants securely, a restraint that keeps the eye entirely on the diamonds rather than the metalwork.

A piece of this scale and stone count is, realistically, a museum-calibre acquisition rather than an everyday brooch. It belongs to the category of jewellery collected specifically for its rarity and its function as a tangible, appreciating asset — fifteen matched or graduated pear brilliants of this size are exceptionally difficult to source as a set today, and pieces of this magnitude rarely return to the open market once acquired by a serious collector. For buyers thinking in terms of long-term value alongside occasional wear, this is precisely the category of piece that holds its worth across decades.

When worn, the graduated pear formation reads dramatically on a lapel or the centre of a formal gown, ideal for the most significant evenings — a state dinner, a major gala, an occasion where the piece itself becomes part of the conversation. The pin mechanism has been engineered to securely carry the substantial combined weight of fifteen large diamonds, a structural requirement most estate brooches were never designed to meet.

Independent certification for the diamond content, stone by stone, is available on request, and given the scale of this acquisition we strongly encourage serious enquirers to request full documentation before proceeding. This brooch has been entered into the Legacy house register as a flagship diamond holding, and our senior advisors are available for a private, unhurried consultation covering provenance, condition, and terms.

We welcome a confidential conversation and private viewing at your convenience — pieces of this significance deserve to be seen in person.
