size: 64 x 26mm weight: 14.66 grams material: platinum gemstones: center natural old euro cut 1.00ct, G color, VS1 natural old euro cut, old euro cut, transitional cut diamonds: 3.50ctw, G-H color, VS clarity Notes from the Curator This platinum and diamond brooch radiates the refined exuberance of the Art Deco period, most likely executed during the late 1920s or early 1930s when pierced geometric filigree and bezel-set old European–cut stones defined high jewellery. The design—two symmetrical lobed panels converging on a central sunburst motif crowned by a substantial one-carat diamond—echoes the double-clip brooch architecture fashionable in the era, though here unified into a single composition. Platinum's tensile strength allowed craftsmen to carve delicate openwork galleries and apply milgrain borders without sacrificing structure, a technical feat that white gold could not reliably achieve at this scale. The pairing of transitional-cut and old European–cut diamonds, totalling four and a half carats in near-colourless G–H grades, reflects the period's preference for geometric brilliance over earlier romantic cuts. What distinguishes this example is the radial pave work framing the centre stone: each baguette set into rays that splay outward like architectural sunbeams, a motif borrowed from the era's fascination with speed, machinery, and celestial symbolism.
