Prehnite has an etherial, celestial, pearly opaque inner translucent glow to its nature and structure. Truly a unique one of a kind gemstone material both in color light play, and “holding its own”, in the spectrum of greens offered in the mineral world. This muted apple green specimen has orb like formations within that display how the structure of prehnite forms. A sizable low domed oval cabochon set in 22 karat gold. Open backed base and shank of sterling silver .925 brought to a high polish finish. 8mm shank width. Top measurements are 28mm vertical x 22 mm horizontal x 9 mm gem height. Ring size 9.
