Moissanite is a synthetic gem material with properties that differ from those of diamond. An experienced gemologist will be able to distinguish between diamond and synthetic moissanite. If there is any doubt, the stone can be sent to a qualified independent laboratory for identification. Synthetic moissanite has the following physical properties: refractive index 2.648–2.691, birefringence 0.043, specific gravity 3.22 (it will float in methylene iodide — S.G. 3.32), dispersion 0.104, and hardness 9.25. Under magnification, look for the following characteristics: doubling in appearance of facet junctions, whitish or reflective needles, rounded facet junctions, surface pits, or polish lines.
