Description
Authentic Art Deco era pendant necklace featuring a geometric tiered drop design. The pendant holds a beautiful emerald-cut aquamarine-colored glass stone set in a rectangular frame with ribbed/rolled detailing typical of the 1930s machine-age aesthetic. Suspended on a fine vintage curb chain.
Key Features
High Art Deco geometric styling; desirable emerald-cut stone; 'Machine Age' transition aesthetic; original vintage components.
Authenticity Indicators
Construction style (hinged geometric drop), lack of modern lobed clasps, and the specific 'dirty' oxidation of vintage base metals. High confidence it is a true vintage piece, though costume-grade.
Flaws to Note
Heavy metal oxidation/tarnish throughout; plating loss on high points of the pendant; chain may be brittle due to age; visible grime in the crevices of the stone setting.
Selling Guide
Where to Sell
Etsy (best for vintage), eBay (good for auctions), or Depop (appeals to Gen Z vintage collectors).
Selling Tips
Do NOT over-clean or use harsh chemicals as it may strip the remaining gold plating; use a soft jewelry cloth only. Use keywords like 'Art Deco', 'Machine Age', 'Geometric', and 'Aquamarine Glass'. Photograph against a white background to make the blue stone pop.
