Charles & Colvard developed the JFIRE Unit to demonstrate the superior optical properties of Moissanite. Using a relatively simple technique of shining a light source through a similar sized moissanite jewel and diamond placed in water, the JFIRE Unit dramatically demonstrates the superior fire and brilliance of moissanite.

See the  virtual JFIRE Unit below to see the obviously superior fire and brilliance of moissanite for yourself. Now which jewel would you prefer to wear?
