This tailored clasp is neat and petite. A piece of vintage Japanese incised glass is bezel set in a hand made sterling silver hook clasp. The centerpiece is glass but the color is similar to a deep lapis. The pattern on the glass is art deco in style. It has sharp incised lines that run up and down. The triangle is 12 mm at the widest point and the clasp is 48 mm from ring to ring. See also Light blue incised glass hook clasp.
