Moissanite Comparison: F1 vs MC vs AGS0

MoissaniteCo proudly offers three brands of Moissanite:

1) Forever One Moissanite

Forever One Moissanite is considered the most premium brand of Moissanite available. Forever One Moissanites are created by Charles & Colvard, a USA based company. It is the original creator of Moissanite gems, and has more experience with creating and faceting Moissanite gems than any company on earth. The Moissanite crystal they create is second to none. has been selling Charles & Colvard Moissanite since 2005, and we proudly sell Forever One Moissanite as our core Moissanite brand. Forever One Moissanites are colorless, excellent cut, with near flawless clarity.

2) MoissaniteCo Brand

We introduced our MoissaniteCo brand in 2017 as a less expensive alternative. We offer it for those customers who demand high quality, excellent cut stones, but don’t necessarily need the name brand. They are made of the same type of Moissanite as the Forever One brand. In our opinion they are the best alternative to Forever One Moissanites on the market. While a distinguishing eye may pinpoint small differences, we have found many of our customers don't see the difference because the two are so similar. MoissaniteCo brand Moissanites are also colorless, excellent cut, with near flawless clarity.

3) AGS0 Super Ideal Cut Moissanite

Our AGS0 Moissanites are cut to the super ideal specifications for a round brilliant hearts and arrows diamond. They have a “000” grade according to the cut scale developed by the American Gemological Society. This cut grade is the highest possible in diamonds, and so our AGS0 Moissanites are cut better than 99% of diamonds in the marketplace. As a result the cut, symmetry and polish are perfect in every way.

To create these Moissanites we have partnered with European engineers who cut our AGS0 Moissanites using computers and state of the art robot technology. This a unique aspect to the creation of these stones because Moissanites are typically hand cut, and the quality of the cut is limited to the expertise, time and money of the cutter. Robotic cutting makes super human precision possible, along with consistency of quality from stone to stone. Another unique quality is that the girdle is faceted, unlike other Moissanites in the market.

The AGS0 super ideal cut Moissanites are available in the round brilliant H&A cut from 0.75ct to 5ct. They are colorless with near flawless clarity as well. From time to time we have a small inventory of near colorless stones available upon request.
