Retro Diamond Engagement Ring in Mixed 18K/14K Yellow Gold, Circa 1940s

An old European cut diamond sits high in a four-prong setting at the center of this ring, its deep pavilion and small table giving off the warmer, more candlelit sparkle characteristic of pre-modern cutting rather than the sharper fire of a contemporary round brilliant. Fluted shoulders flank the stone, their parallel grooves catching light in repeating lines against the ring's otherwise high-polish finish. The band mixes 18K and 14K yellow gold, a construction choice common in the period, when jewelers combined karat weights for structural or cost reasons within a single piece. Small in scale but dense with period detail, the ring reflects the more delicate, tailored silhouette 1940s engagement rings favored before the bolder Retro cocktail styles took over.

Excellent vintage condition; no visible wear, damage, or loose stones in photographs. Stamped 14K/18K with additional hallmark. Size 5.75. Weighs 4 grams total.
