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 superior fire and
brilliance of moissanite for yourself.
