Customer Reviews
Good value, free setting
I was looking for a good deal on an engagement ring and found Diamonds-USA. The free setting promotion definitely caught my eye. I got a beautiful princess cut diamond with a solitaire setting. The price felt very fair, especially with that offer. They also had a small discount for paying by wire transfer, which helped me save a bit more. Overall, I felt like I got a really good value for my money, which was important to me as a first-time buyer.
Easy to pick out a ring
So, I decided to finally get an anniversary ring for my wife. I'm not really a jewelry person, but the Diamonds-USA website was pretty easy to navigate. I ended up getting a nice eternity ring, 14k gold. It showed up on time, took about a week and a half to reach my place in Texas. The ring looked good, and she liked it, so that's what matters. No drama, no fuss, just a straightforward shopping experience. Would probably use them again if I needed another piece.
Nice diamond, quick shipping
Bought a lab grown round brilliant diamond. It arrived in 6 days to California. The diamond was IGI certified, as promised. Good quality. Happy with the purchase.
