Moissanite Guide

What is moissanite?

Moissanite was discovered in 1893 in a meteor crater, and is extremely rare and scarce to find in nature. However, the miracle of modern science means most moissanite on the market is lab grown—making it far more affordable than diamonds. We only offer the best of the best moissanite, which is the Forever One moissanite by Charles & Colvard. They are colourless and are graded DEF in the GIA colour grading scale.

Moissanite’s Brilliance & Refractive Index is rated as 2.65-2.69, whereas diamonds are rated around 2.42. That means moissanite is actually more brilliant than diamond!

A purchase of every Forever One moissanite comes with a certificate of authenticity and a Charles & Colvard limited lifetime warranty.

How hard is moissanite?

Moissanite is rated at 9.25 on the Mohs Scale of Hardness, on which diamonds are rated 10 out of 10. It’s much tougher than just about every other mineral used in jewellery.

What is "Eye-Clean"? I see this term frequently in a lot of product pages.

"Eye-Clean" refers to the clarity of moissanite and some other gemstones. This means, broadly, that when looking at your moissanite (or diamond) inclusions are not visible to the naked eye. Under a microscope, however, you may be able to detect small inclusions. An eye-clean moissanite is not a bad gemstone—it is just as brilliant and sparkly as its VVS1-VVS2 diamond counterparts to the naked eye (which of course is how you will most frequently see the ring in your day to day). The presence of small inclusions, if invisible to the eye, is an excellent way to save money on your gem while not sacrificing beauty.

How do I care for moissanite?

Similar to caring for diamonds, simply wash moissanite gently with a mild soap, rinse with warm water, and dry with a microfibre cloth or allow to air dry. How you care for the metals in your ring may vary—find more information about metal care in our metal guide.
