Customer Reviews
Good quality, delivery took a while
I got a 1 carat round cut diamond solitaire pendant. The diamond looks great, really sparkles. The free shipping was nice, but it took 8 days to get to me, which felt a bit long. Overall, happy with the purchase for the price.
Really liked my new earrings
I ordered some lab grown diamond hoop earrings and they're really pretty. They arrived in about a week, which was fine. Customer service was helpful when I had a question about sizing before I bought them. You can tell they're good quality. I'd definitely look here again if I need more jewelry.

Just wondering about their diamonds. Are they like, actually graded by a real lab? Or is it their own certification?
