THE STONE THAT STARTED IN THE STARS
WHAT IS MOISSANITE
A gemstone born from
a meteorite. Grown in a lab.
In 1893, scientist Henri Moissan discovered a rare mineral inside a meteorite crater in Arizona. That mineral — silicon carbide — is what we now call moissanite.
Every Rikaa stone is grown in controlled laboratory conditions and hand-finished for exceptional brilliance.
