Vintage 10K Yellow Gold Blue Spinel & Quartz Ring – Size 5.75, Emerald-Cut Estate Cocktail Jewelry

A striking vintage estate ring crafted in solid 10K yellow gold and set with a vivid deep blue emerald-cut spinel measuring approx. 11.5 mm × 6.3 mm. The center stone is framed by two clear faceted quartz accents, creating a refined three-stone silhouette with elegant balance and contrast.

The sculpted mid-century setting gives the ring height, presence, and architectural symmetry, while the saturated blue spinel delivers gemstone drama without the price of sapphire. This is a collectible fine jewelry piece — bold enough for a statement cocktail ring, yet timeless enough to serve as an alternative engagement ring.

Currently a size 5.75, the ring can be resized by a qualified jeweler.

Collector's Note:

Blue spinel has long been prized as a sapphire alternative in estate jewelry, offering the same rich color saturation with exceptional brilliance and durability. The three-stone format — center emerald cut with flanking accents — is a classic heirloom structure found in fine rings from the 1940s–1970s, making this piece ideal for collectors who value both style and history.
