Some rings feel like they were passed down, not bought. This vintage tanzanite ring centers a petite oval in tanzanite’s dreamy violet-blue, edged with simulated diamonds and set on a slim 14K rose gold vermeil band with quiet Art Deco flair. It is a delicate, wear-everywhere piece — equally lovely as a December birthstone gift, a promise ring or an unconventional engagement ring.

Vintage romance, everyday scale
The design borrows the softness of antique jewelry — a delicate oval, fine detailing and a slender 2 mm band — and shrinks it to an easy, everyday scale that layers and stacks beautifully. It is the kind of ring you forget you are wearing until it catches the light. If you love timeless silhouettes with a little Deco spirit, you will find kindred designs among our tanzanite engagement rings.
The violet-blue oval
The center is a simulated tanzanite, cut as a 6.0 × 4.0 mm oval and created to carry tanzanite’s famous violet-blue — the color that shifts between deep blue and warm violet as the light changes. Petite but full of personality, it gives you the gem world’s most romantic hue in a size made for daily wear. To explore the stone’s meaning and lore, our guide to tanzanite meaning is a lovely read, and there are coordinating pieces across our tanzanite jewelry range.
Simulated diamond accents
Framing the oval are simulated diamonds (cubic zirconia), hand-set to add a crisp flash of white sparkle that makes the violet-blue center look even deeper. It is a bright, budget-friendly way to bring vintage engagement-ring shimmer to a design that stays light and wearable.
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. The rosy tone flatters the cool violet-blue of the tanzanite for a classic, romantic contrast. See how the shade suits other stones across our nature-inspired engagement rings.
The December birthstone
Tanzanite is a modern December birthstone, which makes this ring a heartfelt choice for winter birthdays, holiday proposals and December anniversaries. Its violet-blue tones are long tied to intuition, calm and new beginnings. For more on the month and the stone, see our complete December birthstone guide and our history of gemstones guide.

Frequently asked questions
Is the tanzanite natural or simulated?
The center is a simulated tanzanite — a created stone made to capture tanzanite’s signature violet-blue color. We say so plainly because honesty matters: you get the gem’s famous color and easygoing durability at a friendly price.
What color is the oval in person?
A rich violet-blue that shifts with the light — deeper blue in daylight, warmer violet under indoor lighting. It is the color tanzanite is famous for.
How big is the center stone?
The oval measures 6.0 × 4.0 mm, roughly 0.43 carats — a delicate, understated size that suits everyday wear and layers beautifully with other rings.
What are the accent stones?
The accents are simulated diamonds (cubic zirconia), hand-set for a bright, brilliant sparkle that frames the violet-blue oval.
What is rose gold vermeil?
Rose gold vermeil is real 14K rose gold layered over sterling silver 925 — the warm look of gold at a far easier price. If you would prefer gold throughout, the same design is also available in solid gold.
Is this ring hypoallergenic?
Yes. It is nickel-free and hypoallergenic, built on a sterling silver 925 base, so it is comfortable for sensitive skin.
Is it good for stacking or layering?
Very much so — its slim 2 mm band and petite oval make it easy to pair with wedding bands or other stacking rings for a collected, personal look.
Is tanzanite the December birthstone?
Yes — tanzanite is a modern December birthstone, which makes this ring a thoughtful birthday, anniversary or holiday-season gift. Explore more in our tanzanite jewelry collection.
Can this be a promise ring instead of an engagement ring?
Absolutely. Its delicate vintage styling and meaningful December birthstone make it equally loved as a promise ring, anniversary ring or milestone gift.
Does it come with a matching wedding band?
This listing is for the engagement ring only. Coordinating wedding bands are available separately, and you can browse pairing ideas across our tanzanite couples rings.
How do I care for my ring?
Remove it before showering, swimming or exercise, avoid contact with lotions and fragrance, and store it dry in its velvet box. A soft dry cloth brings back the shine beautifully.
Are the stones ethically sourced?
Yes. All Aquamarise® stones are conflict-free and ethically sourced, and every order arrives gift-ready in a free luxury velvet box with our lifetime warranty.
