Vintage Amethyst Glass and Rhinestone Heart Pin

This is a vintage costume jewelry brooch designed in a stylized heart shape with Victorian revival and mid-century influences. The piece features a central, large round-cut amethyst-colored glass stone held in a circular gold-toned bezel. Surrounding the lower portion of the central stone is a curved row of small circular clear rhinestones, extending down into the point of the heart. The outer frame consists of radiating gold-toned metal bars, creating a sunburst or 'beating' heart effect. The metal appears to be a gold-plated base alloy. Regarding condition, there is notable aged patina and darkening across the gold-toned surfaces, particularly within the recessed areas of the radiating bars. Some of the clear rhinestones show signs of slight yellowing or dulling, which is common in vintage costume pieces. The central purple stone remains clear with no major visible facets chips. The construction suggests a mid-20th-century origin, likely between the 1950s and 1970s. The craftsmanship is typical of mass-produced costume jewelry of that era, utilizing glue-set stones and a plated finish.

I have conducted a visual examination of the Vintage Amethyst Glass and Rhinestone Heart Pin. The piece is a classic example of Mid-Century Victorian Revival costume jewelry, likely dating from the late 1950s to the 1960s. The design utilizes a gold-plated base metal alloy with glue-set chaton rhinestones and a central foil-backed glass cabochon. My inspection reveals significant age-related patina and oxidation in the recessed 'sunburst' channels, which suggests the plating is thinning. The clear rhinestones exhibit 'greying' or 'yellowing,' characteristic of the silver foiling oxidizing over decades. The central amethyst glass remains in good condition with no visible surface abrasions. The market for unsigned costume jewelry of this era is currently saturated; unless a designer hallmark (such as Trifari or Coro) is discovered upon the reverse, the value remains modest. Comparable sales on secondary markets for similar 'unmarked' heart-shaped pins typically fall within the $20 to $50 range depending on the clasp functionality. This valuation reflects its status as a mass-produced decorative accessory rather than a collector's investment piece. Limitations: This appraisal is based solely on digital imagery. A physical inspection is required to verify the integrity of the pin-back assembly, check for undisclosed lead content, and confirm the absence of a hidden maker's mark. Scientific testing such as an acid rub or XRF analysis would be necessary to confirm the exact metal composition, though visual cues strongly indicate a standard base metal alloy.
