Inspired by the concept of navigation, the center u-shaped ring is rose gold with v-shaped prongs holding a Vikings Compass Gemstone, also know as iolite. This gemstone, used by the vikings to navigate, is polarized and is fabled to have shown the direction of the north star. The surrounding bridge ring, or "fathom" meaning embracing arms, does just this to the inner ring. Limited edition of only eleven made, in the USA. By BLISS LAU.
