James Allen – Best Overall Store
Average User Rating: 
If you are in the market for a diamond ring or even a loose diamond then James Allen is the first store you should check out. Our favorite feature at James Allen is that every single diamond ring is available for inspection using high resolution images and a 3D Feature. Along with this feature, every single loose diamond (well over 20,000) can be inspected using a 10x zoom right there on their website. For our full review see our complete James Allen Review.
