A tanzanite engagement ring with true art deco soul — a cushion cut simulated tanzanite in rich violet-blue, framed by a halo of simulated diamonds (cubic zirconia) and set on a delicate 14K rose gold vermeil band. The December birthstone, reimagined for romantics who love vintage glamour.

The Art Deco Design
Every detail of this ring nods to the golden age of jewelry design. The cushion cut center stone sits within a sparkling vintage-inspired halo, its geometric symmetry softened by the warmth of rose gold. The slender 1.6–1.7 mm band keeps all the attention where it belongs — on that unmistakable violet-blue glow.
If you love the character of vintage and antique-style engagement rings but want a stone with modern durability, this design bridges both worlds beautifully.
The Stone: Violet-Blue Tanzanite Color, Everyday Strength
The center stone is a simulated tanzanite — created to capture the legendary violet-blue color tanzanite is famous for, in a stone measuring 8–8.5 on the Mohs hardness scale. That actually makes it more durable for daily wear than natural tanzanite (which measures 6.5–7), so you get the dreamiest color in the gem world with none of the fragility.
Depending on the light, the stone shifts between deep sapphire blue and rich violet — the same mesmerizing quality that made tanzanite one of the most coveted gemstones of the last century. The halo and shoulder accents are simulated diamonds (cubic zirconia), hand-set for maximum sparkle.
The December Birthstone
Tanzanite is the modern December birthstone, making this ring an especially meaningful choice for December birthdays, winter proposals, and anniversaries. Its violet-blue tones have long been associated with intuition, calm, and new beginnings — a fitting stone for the start of a new chapter.
The Metal: 14K Rose Gold Vermeil
The band is crafted in solid 925 sterling silver and finished in 14K rose gold vermeil — real gold over precious silver, giving you the blush warmth of rose gold with a hypoallergenic, nickel-free foundation. The rosy tone plays beautifully against the cool violet-blue of the tanzanite, a color pairing straight out of the art deco playbook.

Tanzanite Engagement Ring FAQs
Is the tanzanite in this ring natural or simulated?
The center stone is a simulated tanzanite — a created stone that captures the signature violet-blue color of tanzanite. We state this clearly because honesty matters to us: you're getting tanzanite's iconic color with greater everyday durability, at an accessible price.
Is simulated tanzanite durable enough for daily wear?
Yes — at 8–8.5 on the Mohs hardness scale, it's actually harder than natural tanzanite (6.5–7), making it better suited to everyday wear as an engagement or promise ring.
What color is the stone in person?
A rich violet-blue that shifts with the light — deeper blue in daylight, warmer violet in evening and indoor lighting. It's the color tanzanite is world-famous for.
What are the accent stones?
The halo and accents are simulated diamonds (cubic zirconia), hand-set for a bright, vintage-inspired sparkle around the cushion cut center.
