MARINER Titanium Milgrain Engraved Finish Men’s Wedding Ring with Blue Plating Inside Rightfully named MARINER, this titanium ring has a Milgrain finish. The engravings are beautiful, and they wrap around a flat, polished ring with clean edges. The interior of the band is shaded a brilliant blue, adding to the panache. Titanium has more durability than gold, platinum, and even stainless steel. It’s strong yet lightweight and will not crack under pressure. Titanium is also a hypoallergenic metal that does not contain nickel, making it a great choice for people with sensitive skin. Comfort Fit – domed interior band slides over the knuckle easier with less friction. The flat interior and clean edges blend with the skin creating a seamless look.
