Both the rainbow and the storm that created it– this ring's design perfectly encapsulates the spirit of the brutalist aesthetic! There are few more distinctive jewelry styles than brutalism. Its beauty is in its unusual forms, inspired by the rougher parts of nature. Where other naturalistic design movements focused on the soft, rounded curves of flowering plants, brutalism draws inspiration from the more rugged parts of the earth: the bark of a tree, its knotty roots, or the face of a rocky cliff. This c1970 cocktail ring features a five carat opal that contains the entire rainbow! Its stormy 14k gold setting evokes gnarled woody vines that wrap around the entire ring's surface. Full cut diamonds organically surround the stone, glittering like drops of fresh rain. They have a total carat weight of about .66, boast near colorless G-H color grade and fine VS clarity grade. The ring is currently a size 4 and may be carefully sized up or down and carved to match if need be.
