Moissanite is known as one of the most dazzling gemstones in the world. Due to its dazzling and attractive fire, and hardness, it has been loved by the jewelry fashion industry.

However, natural moissanite is very rare. The moissanite currently on the market is synthetic silicon carbide (SiC), which is usually derived from unqualified crystal ingots that have not reached semiconductor grade formed during the production of SiC substrates. But do you know who are the top moissanite manufacturers? We will list the top 5 moissanite manufacturers in China and the top loose moissanite manufacturers in the world.
