Never heard of Tantalum? It is a new and upcoming material in the jewelry industry that has a coloring that falls in between titanium and black zirconium. The unique Cross Satin Tantalum Ring with Designed Sleeve is a great example of this! The flat, grooved edge captures the gray cross satin finish in the center of the ring while the edges remain polished. Then to add even more dimension to this style, there is an interior sleeve with a twisted black and white weave pattern. Shown in an 8mm width and comfort fit band. Proudly made in the US.
