Vintage Mid 20th Century 10KGE Illusion Engagement Ring | Imitation Diamond | Signed ESPO | Sz 5

This vintage 1950s engagement ring from Esposito features a classic two-tone illusion setting that was beloved throughout the mid-century era. The square design pairs a white gold head with a yellow gold shank, holding a glass crystal stone that catches light beautifully—a hallmark of pre-cubic zirconia jewelry craftsmanship. In size 5 and stamped 10K GF, it shows virtually no wear and arrives ready to wear or cherish as a meaningful vintage piece.
