What is moissanite?
Moissanite is a rare, naturally occurring mineral also known as silicon carbide, which was first discovered by the Nobel Prize-winning chemist, Dr. Henri Moissan, at the site of a massive meteorite strike in Arizona. This intriguing new stone was named “moissanite” in his honor. It has a unique brilliance and fire that is very similar to diamond. Its durability and ease of care make it a great choice of engagement rings. Charles and Colvard moissanite is a lab created mineral, grown and cut here in the United States.
Moissanite is approximately 10% lighter in weight than diamond of the same diameter. So moissanites will weigh less in carats when compared to diamonds of the same millimeter size. Some people are more familiar with carat weight than with millimeter size, so when comparing the millimeter size of the loose moissanite available here, the equivalent diamond weights are:
4mm/.22ct moissanite weight/.23ct diamond equivalent weight
4.5mm/.29ct moissanite weight/.33ct diamond equivalent weight
5mm/.45ct moissanite weight/.51ct diamond equivalent weight
5.5mm/.59ct moissanite weight/.64ct diamond equivalent weight
6mm/.74ct moissanite weight/.81ct diamond equivalent weight
6.5mm/.96ct moissanite weight/1.04ct diamond equivalent weight
7mm/1.20ct moissanite weight/1.31ct diamond equivalent weight
7.5mm/1.47ct moissanite weight/1.60ct diamond equivalent weight
8mm/1.74ct moissanite weight/1.92ct diamond equivalent weight
8.5mm/2.08ct moissanite weight/2.26ct diamond equivalent weight
9mm/2.46ct moissanite weight/2.73ct diamond equivalent weight
9.5mm/3.00ctct moissanite weight/3.27ct diamond equivalent weight
10mm/3.36ct moissanite weight/3.66ct diamond equivalent weight
