Vintage 17k White Gold Aquamarine, Sapphire, and Diamond Cluster Brooch

This brooch is designed as a dimensional cluster composed of oval aquamarine cabochons in varying sizes, arranged in a softly contoured, overlapping formation. The aquamarines display a range of pale to medium blue tones with natural translucency and a smooth, polished surface. Between the aquamarine cabochons are round sapphires in a deeper blue hue, each individually prong-set to create points of contrast and visual separation. Small round diamonds are interspersed throughout the design, also prong-set, adding subtle brightness without forming continuous rows or fields. The piece is mounted in white gold with an open-backed construction that allows light to pass through the stones and emphasizes the sculptural quality of the cluster. The reverse features a straight pin stem with a secure clasp, integrated cleanly into the design.
