This mother of pearl wedding band sets a luminous natural mother-of-pearl inlay — soft, ocean-like iridescence — into a slim 4mm high-polish tungsten carbide band. Sleek, minimalist, and timeless: a barely-there profile that works as a modern wedding ring, a stacking band, or an everyday signature. Because mother-of-pearl is natural, each ring's shimmer is its own. Ships with a free luxury velvet jewelry box and free USA shipping.

High polish
Unisex & stackable
One-of-a-kind inlay
The inlay: natural mother-of-pearl
The channel is set with natural mother-of-pearl — the luminous, iridescent lining of shell, shifting through soft ocean tones as the light moves. Its subtle shimmer and depth give the slim band quiet elegance. Because mother-of-pearl is a natural material, color and iridescence vary slightly from ring to ring, so each one is subtly unique. The inlay is sealed and set flush with the band.
Slim 4mm tungsten carbide
The band is high-polish tungsten carbide at a slim 4mm width — refined and barely-there, ideal on its own as a minimalist wedding or promise ring, or stacked alongside an engagement ring or other bands. The comfort-fit interior keeps it smooth for all-day wear.
Built for daily wear
Tungsten carbide is one of the hardest metals used in jewelry — 4 times harder than titanium, 5 times harder than steel, and 10 times harder than gold, second only to diamond. It's scratch-resistant, long-lasting, and hypoallergenic. Curious how it holds up? Read do tungsten rings scratch? and titanium vs tungsten rings.

Mother of pearl band FAQs
Is the mother-of-pearl natural?
Yes — this ring features a natural mother-of-pearl inlay, the iridescent lining of shell. Because it's natural, color and iridescence can vary slightly from ring to ring, so each one is unique.
Is a 4mm band too thin?
4mm is a slim, refined width — ideal as a minimalist band, a women's wedding or promise ring, or a stacking ring alongside an engagement ring. If you'd like something more substantial, ask us about wider widths.
Is this a men's or women's ring?
Both — the slim 4mm design is fully unisex. It works as a women's wedding or promise ring, a minimalist men's band, or a matching stacking ring.
Is it good for stacking?
Yes — the slim 4mm profile is ideal for stacking. It pairs beautifully with engagement rings or layered alongside other bands.
Is tungsten carbide scratch-resistant?
Yes — tungsten carbide is one of the hardest metals used in jewelry, 4 times harder than titanium and 10 times harder than gold, making it ideal for everyday wear.
Is the inlay durable enough for daily wear?
Yes — the mother-of-pearl is sealed and set flush with the band, protecting it from water, dirt, and grime. As with any inlay ring, avoid hard direct impacts.
Will tungsten turn my finger green?
No. Tungsten carbide is hypoallergenic and won't react with skin, sweat, or lotions — the ring will not turn your skin green. Discoloration comes from low-quality or fake metals only.
How do I find the right ring size?
We recommend getting professionally sized at a local jeweler before ordering — it takes just a few minutes, and our team is happy to help you find your correct size. This band fits true to size.
Does this come with a gift box and free shipping?
Yes — every Aquamarise ring arrives in a free luxury velvet jewelry box, and this band ships free within the USA.
