About Moissanite


Every Tianyu Moissanite gem is precisely calibrated and hand-faceted by master gem cutters to maximize brilliance and spark its ultimate fire that increases the refractive index of moissanite.

2.Carat Size

Moissanite is visually proportionate to typical diamond carat weights but is approximately 10% lighter. Most jewelers find it easier to sell moissanite by size rather than weight. A 6.5mm round brilliant natural diamond would have a carat weight of approximately 1.0 compared to a moissanite of the same dimension (6.5mm) which has a carat weight of approximately 0.88. Simply put, to the eye they appear to be the same size, although the weight of the two stones may be slightly different.
