Art Deco Cushion Cut Tanzanite Engagement Ring in 14K Rose Gold Vermeil

A little of the Jazz Age, worn on your hand. This Art Deco tanzanite engagement ring centers a cushion cut stone in the celebrated violet-blue of tanzanite, wrapped in a geometric halo of bright simulated diamonds and lifted onto a slender 14K rose gold vermeil band. It is 1920s glamour reimagined as a December birthstone ring for the incurably romantic.

Art Deco glamour, softened in rose

Every line of this ring nods to the golden age of jewelry design — the era of symmetry, sparkle and unapologetic drama. The cushion cut center sits inside a vintage-inspired halo, its geometry warmed by the blush of rose gold so the effect reads romantic rather than severe. A slim 1.6–1.7 mm band keeps the spotlight exactly where it belongs: on that unmistakable violet-blue glow. It is a design made for anyone who loves the character of period jewelry, and it sits comfortably among our tanzanite engagement rings as one of the most theatrical.

The violet-blue stone

The center is a simulated tanzanite, created to capture the legendary violet-blue that made the gem one of the most coveted discoveries of the last century — and engineered for real-world wear at 8–8.5 on the Mohs scale, a touch harder than mined tanzanite. In daylight it leans toward deep sapphire blue; under warm indoor light it shifts to a richer violet, the same mesmerizing play of color collectors chase. If you love a stone with a story, our history of gemstones guide is a lovely rabbit hole, and you will find coordinating pieces across our tanzanite jewelry range.

A halo of simulated diamonds

Framing the cushion cut is a hand-set halo of simulated diamonds (cubic zirconia), with a scatter of accents along the shoulders for extra brilliance. They throw a crisp, icy sparkle that makes the violet-blue center look even deeper by contrast — a bright, budget-friendly way to bring full Art Deco shimmer to the setting without compromising the color story.

14K rose gold vermeil

The band is crafted in sterling silver 925 and finished in 14K rose gold vermeil — real gold layered over precious silver — giving you the blush warmth of rose gold on a nickel-free, skin-friendly foundation. That rosy tone plays beautifully against the cool violet-blue of the tanzanite, a pairing pulled straight from the Art Deco playbook.

The December birthstone

Tanzanite is a modern December birthstone, which makes this ring an especially meaningful choice for winter proposals, December birthdays and cold-month anniversaries. Its violet-blue tones have long been tied to intuition, calm and fresh starts — a fitting emblem for the beginning of a new chapter.
