WholesaleWhy moissanite
Brilliant, durable and good value
Moissanite is one of the most brilliant gemstones used in fine jewelry. It measures 9.25 on the Mohs scale of hardness, so it is made for everyday wear, and it costs a fraction of a diamond of the same size.
What is moissaniteWhy lab grown diamonds
A real diamond, made above ground
A lab grown diamond is 100% diamond, with the same chemical composition, brilliance and hardness as a mined diamond. It is grown with advanced technology instead of mined, and every centre stone comes with an IGI certificate.
