Above, you will see a moissanite and diamond gemstone laid side by side in a petri dish filled with water. A pin light is used to show the gemstones’ dispersion.
How to Identify Moissanite
View moissanite with a magnifying loupe (10x) through its crown (top) or pavilion (side) facets, and doubling of the back facet junctions can be seen. Diamond, for example, is single refractive and does not show doubling.
Needle-like inclusions are inherent to the process that creates moissanite crystals. Under magnification these inclusions can best be seen when looking through the stone at a 90 degree angle and are located perpendicular to the table. These inclusions, however, do not interfere with reflection, refraction or the dispersion of light.
Dispersion and Refractive Index
The science responsible for the extraordinary fire and brilliance of created moissanite is dramatically shown on page 6. Equal high-intensity lights shine over a moissanite and a diamond. The uniquely superior fire and brilliance of moissanite, due to its high refractive index and dispersion, is illustrated by the wide color spectrum.
There are many diamond and moissanite testers available today. Use testers carefully to best ensure your result.
Charles & Colvard’s Forever OneTM gems are laser inscribed with the words Forever One and other specific number sequences for easy identification.
