The Bamoer jewelry features a mysterious gemstone - Moissanite. Moissanite is the general term for a family of silicon carbide (SiC) crystals. Grown in a lab, they are a good alternative to diamonds, displaying the best optical properties. A stone of similar size, shape, and cut costs 10-20 times less than a diamond. Upon learning that the brand released a collection with these stones, I immediately purchased some for my collection. The ring is beautiful. The stones sparkle like real diamonds. In the center, there is one large moissanite, and on the sides, there are a scattering of small stones. Be careful, you need to choose the right size. There is a 925 hallmark. I am very pleased with both the quality and the fast delivery. In addition, each piece of jewelry comes with a quality certificate with the personal number of your stone and its exact measurements. Also included is a gift box and a cloth for caring for the silver. I highly recommend it for yourself and as a gift.
