MAUI Tungsten Wedding Band with Mother-of-Pearl Inlay This beautiful Tungsten Carbide ring has polished beveled edges and a Mother-of-Pearl inlay displaying iridescent purple, blue, green, white, and black swirls like the shimmering waves in the ocean. Made from the inside lining of oyster and abalone shells, Mother-of-Pearl is a decorative material that has been used for centuries for furniture, musical instruments, and jewelry. Tungsten Carbide—the newest and strongest metal for jewelry that does not scratch easily. Note that the Mother-of-Pearl inlay may chip if the ring is dropped on a hard surface. Comfort Fit – domed interior band slides over the knuckle easier with less friction
