The Moissanite Sterling Silver Size Necklace by TFT is beautiful and sparkles like real diamonds but is a lab made gem. I checked out Moissanite online and found that it is very comparable to a real diamond in look and is a harder stone so chipping or damage unlikely with normal wear and care. When I put mine under a lighted magnifying glass the sparkle and shine and colors are beautiful. Im no expert but I compared the stones to my diamond ring and I couldn't tell the difference. It came nicely packaged in a lidded box within a magnetic square box and a gift bag. There is a Certificate card and you can go online to the GRA (Global Geological Research Academy), but when you bring up the certificate ID number it's basically the same info that's on the card. I find the price of Moissanite jewelry runs the spectrum of price so Im not sure on that but this would make a great gift for a wife or girlfriend (or just for yourself).
