A 4mm moissanite is set in an original five-prong stone setting. The beautiful white shine brightens up the face. Moissanite is a mineral discovered in a meteorite that fell from space 50,000 years ago. By successfully creating it artificially in the United States, it is now possible to wear its brilliance. It has a higher refractive index than natural diamonds and is said to shine about 2.5 times brighter, and its eye-catching beauty is its charm.
