I ordered a 2.5 carat diamond stud earring from here and I am very happy. I retired being a gemologist 6 years ago and I know exactly what to look for. I was specialized in diamonds. I got a vs1 clarity diamond from Edwin Novel Jewelry Design because anything better would make no difference unless you have a high magnified microscope. If I was ordering a 5 carat then I would go with the VVS1 quality but for a 2.5 carat there is no need. I checkout the diamonds and everything was perfect. The cut quality and color was exactly to speck. The metal (setting) was actually very impressive. Jewelry is hand made so some scratches is common but they are amazing jewelers. The earrings were perfect, I have not seen anything like that before. One of the best I have ever seen. Makes me appreciate them even more.
