Reliable, definitely recommend!
I was really scared to make this kind of purchase online. I read all the positive reviews and decided to give them a chance. I’m so glad I did!! My diamond is beautiful! The payment process was quick and easy, my diamond was delivered 10 days after my order was placed.

I had an extremely positive experience…
I was looking for rings online and nothing came up within my style/budget until I came across this site. I was skeptical from it being online, but I was always notified of what was happening behind the scenes. I couldn’t be happier with this company.

Great prices, great customer service!
The prices on this site are significantly lower than other retailers for the exact same diamond. Shipping does take longer than expected, but it was worth the wait, and Sarah did keep me updated the entire process.
