Art Deco Gemstone and Enamel Shield Dress Clip / Brooch by Blum's - Vogue

This is an exquisite Art Deco-era dress clip or brooch, likely dating from the 1920s, presented in its original retail box. The piece features an elaborate design, heavily encrusted with various gemstones and enamel work. Its central motif appears to be a stylized lantern or geometric cage-like structure, rendered in green enamel with what appear to be small diamond accents, flanked by two prominent pearl drops. The main body of the clip is a tapered, shield-like shape, symmetrical on both sides, with intricate scrollwork and floral patterns executed in pave-set diamonds (or diamond simulants) and vibrant blue enamel. Along the tapered sections, there are rectangular-cut green gemstones, possibly emeralds, interspersed with smaller red stones, likely rubies or garnets, and additional diamonds set in ornate patterns. The metal setting appears to be silver or platinum, given the oxidation visible on some surfaces, lending to a blackened patina in areas, which is typical for older silver-set diamond jewelry. The craftsmanship is highly detailed, showcasing significant handiwork in the stone setting and enameling, indicative of high-quality period jewelry. The piece is housed in its original red leatherette hinged case with a cream-colored satin interior and velvet fitted insert. The lid of the case bears the mark "Blum's - Vogue" and "Oak Street- Michigan Ave.", "Chicago", indicating the original upscale retailer. This suggests the piece was retailed by a prominent luxury boutique, hinting at its provenance and inherent quality. The overall condition appears to be good for its age, though some light wear and minor tarnish are visible, consistent with a vintage item. The clasp mechanism, visible on the left side, is a typical articulated bar and pin closure for a brooch or clip, made of a contrasting gold-tone metal, likely brass or gold-filled.
