Moissanites are NOT simulated diamonds. Diamonds are made of a carbon crystal, while moissanites are silicon carbide. Moissanites are lab-created gemstones that have a hardness and light-refracting characteristic that is very similar to a diamond.
No. Should brilliance, fire or color tone ever change, bring your moissanite to Icing On The Ring to have it replaced under Charles & Colvard's Limited Lifetime Warranty.
Although the value of precious gemstones is partly based on their weight, this valuation method does not apply to moissanites. Because moissanites are lab-created, rarity-based valuations no longer apply. Instead, value is based on the cost of technology and energy consumption required to grow the moissanite crystal.
Because moissanites are not diamonds, GIA diamond grading scales do not apply. However, Charles & Colvard produces 2 color classes of moissanites, - Forever One Colorless and Forever Brilliant Near Colorless. Forever One resembles D-F color diamonds, and is suitable for platinum and white gold jewelry; while Forever Brilliant resembles H-J color diamonds, and is best for yellow or rose gold jewelry.
