The emerald cut, reimagined in turquoise
The emerald cut is the connoisseur's shape — long, straight facets arranged in tiers that create a "hall of mirrors" flash rather than fiery sparkle. On a stone this saturated, those step facets pool the turquoise into ribbons of light and give the ring an architectural, art-deco calm. Set in a vintage frame, it feels both antique and current at once. If understated-yet-bold is your language, you will find kindred pieces among our women's engagement rings, our colorful gemstone engagement rings and the wider unique engagement rings edit.
The Paraiba tourmaline
This center is a lab-grown Paraiba tourmaline in the vivid turquoise that made Paraiba legendary — a copper-rich glow that reads almost neon in good light. Lab-grown delivers that coveted color with excellent clarity and consistency, at a price that leaves room in the budget for the wedding to follow. At roughly one carat in an emerald cut, the stone shows its color across a broad, open table for maximum impact. For couples who love a gemstone with a story, our roundup of fantasy-inspired engagement rings is full of inspiration.
Simulated diamond accents
Simulated diamond accents line the design, throwing a crisp white sparkle that frames the turquoise and makes it read even richer. It is a bright, budget-friendly finishing touch that keeps all eyes on the Paraiba at the center. Prefer moissanite or lab-grown diamond accents? Message us — most of our designs can be personalized.
Solid sterling silver with a rhodium finish
The band is crafted in solid 925 sterling silver and finished with rhodium, the same precious metal used on fine white-gold jewelry. Hypoallergenic and tarnish-resistant, the rhodium finish gives the ring a mirror-white luster and a protective shield against everyday scratches, so the silver keeps looking freshly polished. It is the quiet detail that lets a sterling silver ring wear well beyond its price.
Symbolism and the October birthstone
As one of October's two birthstones, tourmaline has long stood for creativity, confidence and emotional balance — a meaningful choice for a proposal, an anniversary or a milestone celebration. Its rare turquoise color makes it a natural fit for someone who values individuality over convention.

Frequently asked questions
What kind of tourmaline is the center stone?
It is a lab-grown Paraiba tourmaline in a vivid turquoise color. Lab-grown gives you that legendary copper-rich glow with excellent clarity and consistency, at a far more accessible price than a mined Paraiba.
What is an emerald cut?
An emerald cut is a rectangular step cut with long, parallel facets. Instead of fiery sparkle it creates a smooth "hall of mirrors" flash that shows off the color and clarity of the stone beautifully.
Why is Paraiba tourmaline so vivid?
Its glowing turquoise comes from traces of copper in the stone. That copper content is what separates Paraiba from ordinary tourmaline and gives it that electric, almost neon look.
What are the accent stones?
They are simulated diamonds that add a crisp white sparkle and make the turquoise center read even richer. If you would prefer moissanite or lab-grown diamond accents, reach out and we will tailor it for you.
What metal is the ring made from?
Solid 925 sterling silver, finished with rhodium. It is hypoallergenic, tarnish-resistant and made to last, with a bright white luster and added scratch protection.
What does the rhodium finish do?
Rhodium is the same precious metal used to finish fine white gold. It gives the silver a mirror-bright, white shine and adds a protective layer that helps the ring stay looking freshly polished.
How big is the center stone?
The emerald-cut center measures approximately 6.0 x 4.0 mm, around one carat — a confident, eye-catching size with a broad table that shows off the turquoise color.
Is tourmaline durable enough for daily wear?
Tourmaline sits around 7 to 7.5 on the Mohs scale, making it well suited to everyday wear with normal care. Avoid hard knocks, and remove the ring for rough activities to keep the stone pristine.
Is this a good engagement or promise ring?
Yes. Its vintage styling and rare turquoise color make it a striking non-traditional engagement ring, promise ring or statement gift for someone who loves vintage charm with a pop of color.
What is the band width and fit?
The band is approximately 2 mm wide with a comfort-fit profile, so it sits smoothly and feels easy to wear all day.
What size should I order?
Select your ring size at checkout. If you are unsure or between sizes, contact us for guidance. Resizing is available and starts from a modest fee.
Are the stones ethically sourced?
Yes. All of our stones are ethically sourced and conflict-free, so you can wear your ring with complete peace of mind.
Does it arrive gift-ready?
Every order ships in a free luxury velvet gift box and is backed by our lifetime warranty, ready for a proposal or to give as a keepsake.
