They currently make their highest quality loose gems under the trademark Forever One. Generic moissanites are, as the name implies, brand less & are not protected by a registered trademark & are therefore more affordable. This does not mean that their quality is inferior or they will not last as long as Forever One stones. I guarantee that both stones are of the highest quality at the most competitive price you can find in the market. LAB DIAMOND COATED The key aspect of this Lab stone is that it is designed to emulate the diamond natural reflection characteristics as closely as is possible, Even to the eye of a trained expert, this stone looks like a real diamond & specialist testing equipment is necessary to determine 100% for sure that this is really a diamond simulant in that it is really a stone coated with an outer layer or Lab Diamond (ie made from Carbon) Many lesser quality man-made stones are easy to detect to the trained eye simply because they are ’too sparkly’ & for this very reason, they can be easily identified. The lower quality lab stones are very easily picked from real diamonds, but this item presents a real dilemma even for the most trained eye. Please do note that although the stone is coated with Lab Diamond to improve hardness & its optical properties, the coating is not thick enough for the industry standard diamond tester to be fooled into thinking this is a real diamond. The thin coating will result in this stone being tested as: not a diamond. Lab Diamond Ring, Engagement Moissanite Wedding White Gold Unisex Anniversary 925 Silver 2933
