This vintage WWII gold-filled US Army Air Corps sweetheart locket features an engraved sunburst pattern centered with a distinctive propeller and wing insignia.

This open vintage heart-shaped pendant features a visible hallmark stamp on the interior reading "1/20 12K GF" alongside the maker's mark "A&Z". [1]

• Material Mark: The stamp indicates 1/20th 12-karat gold-filled (GF) metal, meaning a layer of 12K gold is mechanically bonded to a base metal core.

• Maker: The "A&Z" stamp identifies the piece as being manufactured by the A&Z Chain Company, a notable American jewelry maker active during the mid-20th century.

• Design: The piece is an openable double-photo heart locket typically featuring a decorative engraved or etched exterior (such as floral motifs)

Typical Market Values

• Basic Lockets (Good Condition): Lockets showing minor to average wear typically retail on eBay or Etsy between $45 and $75.

• Premium Lockets (Excellent Condition / Extra Features): Pieces with pristine mother-of-pearl accents, original 1940s chains, or intact cellophanes and paper backing sell closer to $90 to $125. 

Value Drivers

• Insignia Design: The standard "propeller and wings" Army Air Corps logo is relatively common, but specific embellishments like colored enamel or inlaid mother-of-pearl increase visual appeal and value.

• Condition: Intact interior photo frames, original cellophane covers, and hinges that latch securely maximize resale value. Severe brassing (where the gold-fill layer wears away to expose the dark brass underneath) will drop the value closer to the $25 to $35 range
