This is a moissanite (synthetic stone) necklace. Moissanite is a mineral discovered 50,000 years ago from the remains of a meteorite that fell from space. It has a beautiful, eye-catching shine, and is said to have a higher refractive index than natural diamonds, making it about 2.5 times as bright. Natural moissanite is extremely rare, but by successfully creating it artificially in the United States, you can now enjoy its brilliance. It also has excellent durability, making it perfect for everyday use. This is a pave necklace in the shape of an egg that looks like a drop at first glance. In keeping with the bold image of the egg, the chain is passed through the back for a subtle movement. Eggs are a popular design as a lucky motif. * TAKE-UP products are Made in Japan, handcrafted by Japanese craftsmen.
