Cut in cabochon, Star Ruby shines and shows six beautiful rays of light. Named after the Greek word for stars, these starlight lines are called “asterisms.”
Her mysterious phenomenon of reflecting starlight inside is due to the needle-formed rutile, particles of corundum and a kind of titanium oxide. Her internal reflections of light form a star shape. Crescent Vert successfully reproduces her beautiful vivid red starlight.
