Diamond Brooch 4.82, 4.09 of Openwork Design, Set with a Brilliant-cut and Two Pear-shaped Diamonds Weighing 4.82, 4.09

Openwork settings represent one of the more technically demanding approaches to brooch design, requiring a structure strong enough to hold substantial stones securely while removing enough surrounding metal to let light pass through the piece from every angle. This diamond brooch, mounted in platinum, achieves exactly that balance, its openwork frame set with a brilliant-cut diamond and two pear-shaped diamonds weighing approximately 4.82, 4.09 and 3.99 carats respectively, further embellished with old European and trapeze-cut diamonds throughout the surrounding structure of the piece.

The individual carat weights of the three principal diamonds and the platinum mounting are confirmed directly from the piece's own documentation, along with the old European and trapeze-cut diamonds used throughout the openwork frame — an unusually specific and well-documented record for a piece of this age and complexity. Individual clarity and colour grading remain on request pending further verification; a formal gemological report covering the full composition is prepared for any serious enquiry received. Three diamonds each weighing roughly four carats represents a genuinely substantial combined weight for a single brooch, and the openwork platinum structure required to support them securely while remaining visually light is itself a considerable technical achievement in its own right.

A piece of this scale and complexity functions as a serious centrepiece — worn on the lapel of a formal evening coat, as the sole ornament on a gown, or acquired specifically as a significant addition to a collection built around important platinum-era diamond work of real substance. The trapeze-cut diamonds in particular are a relatively unusual inclusion, their angular geometric form adding a modern-feeling structural note within an otherwise classic openwork composition throughout the piece. The mounting is built substantial, appropriate to the combined weight of three sizeable diamonds it must carry securely.

Combined weights approaching thirteen carats across three well-matched diamonds are genuinely uncommon to find intact within a single period openwork setting today. Every gemstone offered through Legacy undergoes rigorous internal review, and independent certification is arranged on request, particularly recommended given the scale of the diamonds involved in this piece. This brooch is recorded in the Legacy register as LD-BR-0097. Openwork platinum pieces of this ambition represent a level of bench work rarely attempted in contemporary production runs, making an intact surviving example a genuine object of technical interest to serious collectors. We invite serious collectors to request the full report or arrange a private viewing at their earliest convenience.
