The beautiful midnight black of rainbow obsidian is alight with sparkly stars of natural gemstones. Blue topaz, red garnet, blue iolite, and purple amethyst swoop around the obsidian in glittering arc of color and light. A wavy openwork scroll design of sterling silver adds a shapely whimsical touch to this ode of the night sky. Measures 1" long x 7/8" wide. Made in the USA.
