Mid-Century 14K Gold Purple Sapphire Ring (3ct, Size 7)
A bold and refined artifact of California’s mid-century design movement, this vintage ring features a striking ~3 carat lab-created purple sapphire in a clean, emerald step cut. The stone’s saturated reddish-plum hue with violet undertones is both regal and rare—especially in a cut known more for elegance and architectural clarity than sparkle. Likely a chrome-doped flame-fusion sapphire, this gem type rose to popularity between the 1940s–1970s as jewelers embraced color, innovation, and bold statement pieces.
Set in solid 14K yellow gold (clearly hallmarked), the ring’s total weight is 4.35 grams. The wide shank, squared shoulders, and high open gallery all suggest mid-century modernist design—favoring clean lines, gem-forward focus, and lasting wearability. The sturdy four-prong setting adds to the ring’s functional beauty.
Inside the band is a lesser-known maker’s mark, “XPS”, likely tied to a small studio or private casting firm. Sourced from a Sonoma County estate alongside other artisan pieces, this provenance supports the theory that it was created or retailed locally by a regional craftsperson or boutique.
