Vintage Amethyst Glass and Clear Rhinestone Costume Jewelry Set (Necklace, Bracelet, and Screw-back Earrings)
Unbranded (Attributed to Coro or Lisner style) · Jewelry & Watches > Vintage Costume Jewelry

Era / Decade
Late 1940s to Early 1950s based on screw-back earring mechanisms, fold-over clasps, and snake-link/chevron plating style.
Material
Silver-tone base metal (likely rhodium or nickel plated over brass or pot metal), emerald-cut faceted amethyst glass stones, and round-cut clear paste/glass rhinestones.
Condition
Fair to Good. Visible heavy patina and tarnish on the metal; possible 'verdigris' (green oxidation) in crevices. Stones appear intact but may have 'sick' (yellowing) foil backing on the clear rhinestones due to age.
Demand Level
Moderate. Amethyst colors are steady sellers, but the market for unbranded mid-century sets is standard unless identified as a major designer.
Resale Value
Estimated Resale Value
Low: $25.00 | Mid: $45.00 | High: $65.00 (as a complete three-piece set)
Estimated Retail Value
$25.00 - $40.00 (original mid-century retail price equivalent adjusted for inflation)
Comparable Sales
Recent eBay sales for unbranded 3-piece silver-tone sets range from $35 to $55. Signed sets (Coro/Trifari) in similar styles sell for $85-$120.
Description
Mid-century vintage costume jewelry parure includes a choker-style necklace, matching link bracelet, and screw-back earrings. Features royal purple emerald-cut center stones flanked by glittering clear rhinestone accents set in a classic silver-tone articulated chevron link chain. Perfect for vintage collectors or Old Hollywood glamour styles.
Key Features
Complete three-piece 'parure' set (rare to find all pieces together); popular purple amethyst colorway; classic Art Deco-influenced Mid-Century design; screw-back earrings are highly collectible for non-pierced vintage enthusiasts.
Authenticity Indicators
Construction matches post-WWII manufacturing; screw-back findings are period-correct; lack of 'Sterling' stamp confirms costume-grade base metal. Medium confidence in era attribution.
Flaws to Note
Significant tarnish and darkening of the silver-tone finish; requires professional cleaning; clear rhinestones show slight dimming/greying; metal may be brittle due to age.
Selling Guide
Where to Sell
Etsy (best for vintage sets), eBay (best for auctions), or Ruby Lane (if higher quality confirmed). Local vintage boutiques for immediate sale.
Selling Tips
Do NOT use harsh liquid jewelry cleaners as they can ruin the foil backing of the rhinestones. Use a dry ionic cloth. Use keywords like 'Paraure', 'Mid-Century', 'Rockabilly', and 'Prom' in the title. Take photos against a black velvet background to make the purple stones pop.
