What is Moissanite?
Moissanite is a mineral discovered by French chemist Henri Moissan in 1893 while studying a fragment of a meteorite in Arizona. This rare mineral is mostly found on cool luminous stars outside our solar system. Due to its stellar origin, moissanite is sometimes referred to as Stardust or Space Diamonds. Since it's rare to find moissanite in its natural form, all forms used for jewelry are lab created. Like diamonds, moissanite is composed primarily of carbon, with the addition of silicon (the same mineral used for computer chips).
Is moissanite the same as cubic zirconia (CZ)?
No! While both moissanite and cubic zirconia gems are lab created and more environmentally friendly than diamonds, moissanite is more similar to diamonds and the best diamond alterative!
First, like diamonds, moissanite is extremely durable. In fact moissanite is 3 times more resistant to breaking and chipping vs cubic zirconia.
Second, moissanite is more resistant to dirt and easier to clean vs cubic zirconia which will quickly become cloudy with wear.
Third, moissanite has a refractive index more similar to diamonds (2.65 and 2.42) vs cubic zirconia at a much lower value (2.15). Cubic zirconia looks more glassy and lack the sparkle and flash of moissanite and diamonds.
