Moissanite FAQ

What is moissanite?

Moissanite is a lab-grown gemstone composed of silicon carbide. Originally discovered in a meteorite crater in 1893 by Nobel Prize-winning scientist Henri Moissan, it is now sustainably created in laboratories. Moissanite has a refractive index of 2.65–2.69, giving it exceptional brilliance and fire—more than any other gemstone including diamond.

What metal is Montier jewelry made of?

All Montier jewelry is crafted with 14K Gold PVD plating over 925 Sterling Silver. PVD (Physical Vapor Deposition) is a precision coating process that bonds 14K gold to a solid sterling silver base, creating a durable and beautiful finish.

How does moissanite compare to diamond?

Moissanite rates 9.25 on the Mohs hardness scale (diamond is 10), making it extremely durable for everyday wear. Its higher refractive index produces more brilliance and rainbow-like fire than a diamond. It is also sustainably lab-grown and significantly more affordable.

Is moissanite a real gemstone?

Yes. Moissanite is a genuine gemstone—silicon carbide (SiC)—with distinct physical and optical properties. It is lab-created for sustainability and consistency, but it is chemically and physically a real stone, not a simulation.

How do I care for my Montier jewelry?

To keep your jewelry looking its best, avoid exposing it to harsh chemicals such as chlorine, bleach, or perfume. Wipe with a soft cloth after wear and store in a jewelry box or pouch when not in use. Moissanite can be cleaned gently with warm soapy water and a soft brush.
