Customer Reviews
Good value, just wish shipping was faster.
Last month, I was looking for oval cut lab diamonds and Plum Diamonds had some great options. Their selection was good, and the certification was clear, which was important to me. The referral program code saved me a good amount too. My only small gripe was the shipping took a little longer than I expected.
Great value on a solitaire ring
As a first-time buyer, I was looking for the best deal on a solitaire engagement ring. I spent a lot of time comparing prices. Plum Diamonds had a really competitive price for a beautiful round cut lab diamond, especially after finding a first-order discount. The free shipping was a nice bonus too. I felt like I got a high-quality ring without overpaying. The whole process was smooth and the ring looks fantastic. Definitely felt like a smart purchase for my budget.
Amazing ring, beyond expectations!
I just received my custom lab grown engagement ring and it's absolutely stunning! The whole design process was so easy and the team was really helpful with my ideas. My fiancee is going to love it, I know it! The details on the hidden halo ring are perfect, and the radiant cut lab diamond just shines. I will definitely be back for wedding bands, thank you Plum Diamonds!
Good quality, delivery a bit slow
I ordered a pair of lab grown diamond studs from Plum Diamonds. The quality of the diamonds was really good, very sparkly and well-matched. The setting felt sturdy too. Shipping took about 8 days to get to me in Florida, which felt a little long compared to other online jewelry stores. Overall, I'm happy with the purchase but wish the delivery was a bit quicker.
