Ostertag, 18K Gold Sapphire Diamond Bracelet

This Ostertag bracelet is built around a wide, articulated gold lattice composed of repeating triangular links. Each element is individually constructed and invisibly hinged, allowing the bracelet to drape fluidly around the wrist despite its architectural geometry.
The sculptural clasp features meticulously aligned calibré-cut sapphires and pavé diamonds, demonstrating exacting gem-setting skill. Architectural yet wearable, it balances mechanical sophistication with refined haute joaillerie elegance.
