My boyfriend gave this to me for our 6-month anniversary, and wow, is it gorgeous! The pendant is not too big, and not too small. It's just perfect. The necklace itself is a nice box-chain; not a flimsy chain that usually comes with jewelry pendants. Everything looks to be of very high-quality. And the diamonds, WOW. They are super sparkly. Sure, they may not be huge, but the cut and clarity are excellent; every stone sparkles greatly, and there is not a single cloudy stone; not even a little cloudy. Oh, and if you look closely, the stone at the bottom of the heart is bigger than the rest as well. :o)
