With a higher refractive index than any other gemstone or diamond, it can simulate larger diamonds at great value. Its hardness (9.25 on the mohs' scale) makes it extremely difficult to scratch even a sapphire or ruby and makes it ideal for accessorizing your fine jewelry pieces!Tianyu Gems Co., Ltd. is a professional manufacturer of moissanite jewelry, which was formally registered in 2009.
