Customer Reviews
Amazing emerald cut diamond!
Just received my emerald cut diamond and it's absolutely stunning! The clarity and sparkle are incredible. I also got a classic platinum setting and it perfectly complements the stone. The whole process was so smooth from picking the diamond to checking out. It arrived super fast, insured and everything. I'm so happy with this purchase, it truly exceeded my expectations. I'll definitely be back for an anniversary ring next year!
Fast service, great diamond
Bought a lab-grown princess cut diamond. It arrived quickly, within 5 days to New York. Diamond looks fantastic. Easy to order. Good quality for the price.
Got my anniversary ring
So, I decided to treat myself to an anniversary ring, a nice pave diamond band this time. It arrived earlier this week and I'm really happy with it. The process was super easy, just picked what I liked and checked out. It got to my place in Texas pretty quick, within a week. The ring sparkles a lot more than I thought it would, which is a nice bonus. Definitely felt good getting it, no hassle at all.
Always a great experience
This was my third purchase from Diamonds-USA, and they've been consistently reliable. I ordered another pair of diamond stud earrings. Just like with my previous orders, the quality was excellent, and the shipping was fast and secure. It reached my home in Florida in about 4 days. It's why I keep coming back; I know what to expect and they always deliver. Their range of settings is always top-notch too.
Good ring, delivery could improve
I bought a custom-built engagement ring with a round brilliant diamond. The ring itself is beautiful, and the diamond is exactly as described with its GIA certificate. The customization process on the website was straightforward. My only slight critique is that the delivery took a bit longer than I anticipated; it was closer to 10 days to reach me in California, which felt a little drawn out. Customer service was helpful when I inquired about the delay, but speeding up that last leg would make it a perfect experience. Good value overall.

Hey, thinking of getting a custom engagement ring here. Does anyone know how long it usually takes for them to ship it out after ordering?
Are their lab grown diamonds actually good quality? I'm a bit skeptical about buying a diamond online without seeing it first.
