DEF VS White Color Lab Grown Diamonds Moissanite Loose Marquise Moissanite Cushion Cut 3*3-5*5m

Q1: 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.

Q2: 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 not 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.

Q3: 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.

Q4: How should I care for my moissanite jewelry?

A: As with any fine jewelry item, an ultrasonic cleaner can be used. However, it is the 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.

Q5: Do you accept OEM service?

A: OEM is warmly welcomed and we have rich successful experiences in doing OEM projects. What's more, we have design team to give you professional advice on package.

Q6: Is there any guarantee on bulk order?

A: No worries about this. Due to our advanced production technology and strict quality testing, every piece of moissanite sent from us is quality guaranteed.

Q7: What's your MOQ? A: In order to build a long-term and stable cooperation, we accept 1 carat as a sample order for you to test our quality.
