Zircon is one of December’s birthstones. It is a colorful gem with high refraction and fire that’s unfairly confused with cubic zirconia. It is a completely distinct, natural species, found in Sri Lanka, Burma, Cambodia, and Australia. Zircon comes in blue, white, yellow, purple, green, gray, red, pink, orange, and brown. Its hardness is 7.5 on the Mohs scale.
