Alternatives vs CZ

The Nexus Diamond™ Alternative vs Moissanite

Both the Nexus Diamond alternative and moissanite are beautiful, heirloom quality alternatives to diamonds. Like the Nexus Diamond alternative, moissanite is nearly as hard as diamond and will last forever—however, it has different optical properties that cause it to look quite distinct.

Moissanite does not look much like a diamond.

Moissanite is a gorgeous stone, but if you are looking for a diamond or diamond alternative engagement ring, then it is important to know that moissanite rings have their own distinctive look. It has more fire and brilliance than a diamond, which makes them beautiful but much more sparkly. This can make them easy to tell apart from a diamond, especially in the sunlight. But if you love the brilliant sparkle, then moissanite could be a great choice for you.

If you choose moissanite for your engagement ring, buy from a premier source. Charles And Colvard™ are the creators and sole U.S. manufacturers of moissanite.
