Usually when I buy Roman glass from Afghanistan it is blue or green. These beads came in a brown tone and I was so glad because it was earthy and different. However, as I wore mine for a few months the coating came off to reveal the beautiful colors of Roman glass. The much more typical greens and blues. This necklace also includes turquoise from Afghanistan, ruby from India, Roman glass from Afghanistan, crystal from Czechoslovakia, carnelian and amethyst from Brazil, Apple coral from Vietnam, Hill tribe silver from Thailand, and a small amount of 2000 year old turquoise from the Silk Road area of Asia. The crescent pendant is made of sterling silver. 16 inches with 2 inches of extender chain.
