Moissanite is a mineral discovered in the remains of a meteorite that fell from space 50,000 years ago. Its beautiful, eye-catching sparkle is very attractive. It has a higher refractive index than natural diamonds and is said to shine about 2.5 times brighter. Natural moissanite is extremely rare, but thanks to the success of creating it artificially in the United States, it is now possible to wear its brilliance on your own. It also has excellent durability, making it perfect for everyday use. The center moissanite, which has a particularly strong shine, is not finished as a solitaire, but by adding six stones, it gives off an elegant yet special feeling that can only be achieved with moissanite. * TAKE-UP products are Made in Japan, handcrafted by Japanese craftsmen.
