My husband got me this ring and I love it! I couldn't be happier! It is a size 6.5 and it fits perfectly! the diamond it's a good size (5 mm) and very sparkly! The ring is not as thick as it looks on the picture, it's about 2 mm but it goes perfect with the size of Diamond and ideal size to add your wedding band. Great Price, Beautiful Ring! I'm a Very happy Wife!!
