Moissanite is also known as silicon carbide. In nature, silicon carbide is created over millennia by a combination of extreme heat and pressure. These gems are more durable than diamond, sapphire, ruby, or emerald.
Will the brilliance of moissanite ever fade?
No. We provides a Limited Lifetime Warranty which guarantees that every Moissanite gemstone will maintain its brilliance and fire for its lifetime.
Will moissanite fade or change color over time?
No. There are no likely situations in which the color of moissanite will be permanently changed. Moissanite does undergo a temporary color change when exposed to extreme heat (for example, from a jeweler’s torch during jewelry repair), but with proper bench techniques there will be no lasting damage, and the gem will return to its normal color once it cools.
Is it true that moissanite can test positive as diamond using some conventional equipment?
Yes. The physical properties of created moissanite are very similar to those of diamond, and moissanite will test positive as diamond using a thermal diamond tester.
