A neon glow you can spot across the room. This Paraiba tourmaline ring lifts a vivid blue-green princess-cut stone on a split-shank band of 14K rose gold vermeil, framed by simulated diamonds for extra brilliance. The warm rose metal against that electric blue-green makes an unexpected, striking pairing — a bold choice for an engagement ring, a promise ring, or an October birthstone gift she’ll never want to take off.

The neon Paraiba color
Paraiba tourmaline is famous for one thing: an electric, almost glowing blue-green that no other gemstone quite matches. The princess-cut center captures exactly that signature neon tone, its crisp step-and-brilliant facets catching the light so the color seems to radiate from within. It is a color built to be noticed — the sort of confident, unexpected stone that stands out among unique engagement rings and colored gemstone engagement rings alike.
The center stone is a lab-grown tourmaline — a genuine tourmaline created in controlled conditions, which is what makes this striking Paraiba color available at an accessible price. Naturally mined Brazilian Paraiba ranks among the rarest and costliest gems in the world, so a lab-grown stone lets you enjoy the same vivid look without the rare-mineral price tag.
The split-shank setting
The band splits gracefully as it approaches the center stone, forming two slender shoulders that lift and frame the tourmaline. A split shank does two things at once: it makes the center stone look larger and more elevated, and it lends a refined, designer feel to the profile. Simulated diamonds trace the design for extra sparkle around the neon center — a bright, budget-friendly accent that keeps all eyes on the color. The sculptural, organic line of the split shank sits comfortably alongside our nature-inspired engagement rings.
A meaningful October birthstone
Tourmaline is one of the two birthstones for October, so this ring carries built-in meaning for an autumn birthday. Paired with the romance of rose gold, it works beautifully as a birthday gift, an anniversary piece, a promise ring, or a colorful alternative engagement ring for someone who loves to stand out. If you are shopping for a pair, our roundup of the best matching rings for couples is a great place to start.
14K rose gold vermeil
The band is crafted in 14K rose gold vermeil — real 14K rose gold over sterling silver 925, giving you that warm, blush-pink glow over a substantial base. Because the metal is nickel-free, it is hypoallergenic and comfortable for everyday wear. The rose tone also plays beautifully against the cool neon of the tourmaline, a warm-and-cool contrast that makes the color pop even harder.

Sizing & care
Choose your size at checkout. If you are unsure or between sizes, message us before ordering and we can help. Tourmaline is durable but happiest with a little care: clean gently with warm water, mild soap and a soft brush, then pat dry. Avoid ultrasonic and steam cleaners, harsh chemicals and sudden temperature changes, and store the ring on its own so the stone stays bright and the setting stays snag-free.
Paraiba tourmaline ring FAQs
Is this a real Paraiba tourmaline?
The center is a genuine tourmaline that is lab-grown, created in controlled conditions to achieve the vivid neon blue-green Paraiba is known for. It is not a naturally mined Brazilian Paraiba — those are among the rarest, costliest gems in the world. Lab-grown gives you the same striking look at a far more accessible price.
Are the accent stones real diamonds?
The accents are simulated diamonds (cubic zirconia), chosen to add bright sparkle around the neon center while keeping the ring affordable. If you’d like moissanite or lab-grown diamond accents instead, reach out before ordering and we’ll be glad to help.
What is rose gold vermeil?
Rose gold vermeil is real gold over sterling silver 925 — here, 14K rose gold over a solid sterling base. You get the warm, golden rose look at an easier price than a piece made of gold throughout. If you’d like gold all the way through, the same design is also available in solid gold.
Is Paraiba tourmaline an October birthstone?
Yes. Tourmaline is one of October’s two birthstones, which makes this ring a thoughtful and personal gift for an October birthday.
Can I wear this as an engagement ring?
Absolutely. Its bold color and elevated split-shank setting make it a beautiful colored-gemstone engagement ring for anyone who wants something more vibrant than a classic diamond. It is equally lovely as a promise ring.
What is a split-shank setting?
A split shank is a band that divides into two slender strands as it nears the center stone. It frames and lifts the gem, makes it appear larger, and adds an elegant, designer-style silhouette.
How big is the center stone?
The princess-cut center measures about 6.0 × 6.0 mm, roughly 1.0 carat. It gives the neon color real presence on the hand while keeping the crisp, square outline that makes a princess cut so striking.
How durable is tourmaline for daily wear?
Tourmaline sits at 7–7.5 on the Mohs scale, comparable to many popular colored center stones and suitable for daily wear with reasonable care. Avoid hard knocks, harsh chemicals and ultrasonic cleaners as general best practice.
How does lab-grown tourmaline compare to natural?
Chemically and visually, a lab-grown tourmaline is a real tourmaline. The difference is origin: ours is grown in a lab rather than mined, which gives a cleaner, more consistent neon color and a much friendlier price than rare natural Paraiba.
Is the stone ethically sourced?
Yes. Because the tourmaline is lab-grown, it is inherently conflict-free and kind to the earth, with no mining required.
Is this hypoallergenic?
Yes. The 14K rose gold vermeil over sterling silver 925 is nickel-free and hypoallergenic, so it stays comfortable for sensitive skin and everyday wear.
Does it come with a gift box?
Every order arrives in a free luxury velvet gift box and is backed by our lifetime warranty, so it’s ready for gifting or proposing the moment it lands.
