Lana Paraiba Tourmaline Ring- Sterling Silver

There is no other blue like Paraiba. It is a turquoise so electric it looks lit from inside — a color that made an obscure Brazilian tourmaline famous almost overnight. The Lana ring sets a 6.0 mm lab-created Paraiba tourmaline in that neon turquoise into a twisted vine band of solid 925 sterling silver, with simulated diamonds tracing the curve. Organic setting, unnatural color, and the contrast is the point.

The Color That Started It All

Paraiba tourmaline takes its name from the state in Brazil where the first stones were found in the 1980s, and it caused a genuine stir in the gem trade because nothing else looked like it: a vivid, glowing blue-green that reads as almost fluorescent next to ordinary blue stones. Natural material from that original source is now among the scarcest gem material on earth. The stone in this ring is a lab-created Paraiba tourmaline, which is how a color this saturated ends up on a ring at this price rather than in an auction catalog. Our complete guide to blue gemstones puts it alongside the alternatives.

Why a Round Brilliant Suits It

A color this intense does not need help — it needs light moving through it. The round brilliant cut is the most efficient shape for returning light back out through the top of a stone, and on a neon turquoise that translates into a center that appears to glow rather than merely reflect. At 6.0 mm and approximately 0.76 ct it is a modest stone by measurement and an immodest one by presence, which is the trade most people are actually looking for in a colored center.

The Twisted Vine Band

Rather than a plain shank, the band splits into ribbons that wind around each other like a climbing vine, with simulated diamonds set along the curve. Two things follow from that. The twist keeps some surface always angled toward the light, so the band stays alive on the hand instead of going flat. And the organic, growing shape deliberately contrasts with the almost synthetic-looking brightness of the stone — nature-inspired metal, otherworldly color.

Sterling Silver, Rhodium Finished

The band is solid 925 sterling silver with a rhodium finish. Rhodium is a platinum-group metal, and finishing sterling with it gives the silver a brighter, whiter luster and an added layer of protection on the surface — a standard we apply across our sterling range, and the right choice here because a cool white metal keeps the turquoise reading vivid rather than muddied. The ring is nickel-free, hypoallergenic, and comfort fit. Read what 925 sterling silver means, or see the range in sterling silver engagement rings.

October's Stone

Tourmaline is one of October's birthstones, and it is the one that gives the month its range — the mineral family spans nearly every color there is, which is why October birthday jewelry does not have to mean pink. Our October birthstone guide covers the family, and there is more in this color story in teal gemstone jewelry.

Sizing & Care

The ring is made in the size you select, so measure with our ring size guide before ordering, and remember that a comfort-fit band can feel slightly snugger than a flat band of the same nominal size. For care, wipe the ring with a soft, dry cloth after wearing and use a soft brush along the twist, where skin oils collect between the accent stones. Keep it clear of household cleaners and chlorinated water and store it dry — our guide to cleaning sterling silver covers the routine.
