Q: What gives moissanite its fire?
A: A gemstone's fire is determined by a gemological property called dispersion. Moissanite's dispersion is 0.104, which exceeds that of any gemstone, including diamond, ruby, sapphire and emerald.

Q: Will moissanite fade or change color over time?
A: 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 from a jeweler's torch during jewelry repair, but with proper bench techniques there will be no lasting damage, and the stone will return to its normal color once it cools.

Q: Is moissanite resistant to scratching?
A: Yes. Moissanite is durable, tough and extremely resistant to scratching and abrasion. With a hardness of 9.25, moissanite is harder than all other gemstones except diamond. 

Q: How should I care for my moissanite jewelry?
A: As with any fine jewelry item, an ultrasonic cleaner can be used. However, it is best to be gentle with your valuable treasures. You can also clean your moissanite jewelry using a commercial (non-acid based) jewelry cleaner or with mild soap and water using a soft toothbrush.
