We sell Created Moissanite Stones by Charles and Colvard "Only". We do not sell imperfect stones, seconds or throw aways. All of Amants By Design's Moissanite jewelry and Loose stones come with a Charles & Colvard Certificate of Authenticity & limited lifetime warranty. Because all Moissanite stones are created by Charles and Colvard, the stones are all hand picked, inspected and excellent in clarity (VS or better), quality, and color. Similar quality diamonds would cost ten times the amount.
