Vintage Victorian Revival Dragon's Breath Glass Shield Brooch

This is an ornate Victorian Revival style pendant-brooch featuring a shield-shaped central frame of antiqued silver-toned metal, likely pewter or silver-plated brass. The piece's focal point is a large, oval cabochon of 'Dragon's Breath' (Mexican Opal) glass, which displays a shifting iridescent play of blue and pink flashes against an amber-red background. The frame is intricately designed with scrolled openwork, decorative beading, and a series of small, multi-colored rhinestones in shades of amethyst purple, emerald green, and fuchsia pink. At the top of the design is a crown-like arch featuring three small stars. A articulated, matching metal dangle hangs from the base, also set with a single green rhinestone. The metalwork shows a dark, aged patina consistent with mid-20th-century costume jewelry, likely dating from the 1940s to 1960s. The construction is solid, using prong and bezel settings for the stones. While no maker's mark is visible on the front, the style is reminiscent of companies like 1928 Jewelry Co. or Art. The piece appears to be in good vintage condition with all stones present and minimal wear to the metal finish.
