Customer Reviews
Consistent service, reliable quality
This was my third time buying from Plum Diamonds, and like before, the experience was smooth. I got a simple gold wedding ring this time, after previously buying a necklace and some earrings. Their lab diamonds are always certified, which I appreciate, and the quality has been consistently good. Shipping was free and arrived within a week. I keep coming back because I know what to expect, and they deliver. No surprises, which is a good thing for online jewelry purchases.
Custom ring process was detailed
I went with Plum Diamonds for a custom lab grown engagement ring. The process started with their online design tool, which was intuitive enough to get a basic idea. After that, I spoke with a designer who walked me through stone selection for a cushion cut lab diamond and band options, even showing me CAD renderings. They were patient with my questions, and the communication was excellent via email. The ring arrived in about four weeks, securely packaged, and it was stunning. The certification for the diamond was included. I used their complimentary resizing service a few weeks later, which was also handled efficiently. It was a big purchase, and they made it feel manageable.
Nice pendant, fast shipping
Ordered a lab grown diamond pendant. It arrived quickly and looked great. Good quality for the price. Would buy again.
Good quality, slower delivery
I ordered a pair of lab grown diamond studs. The quality was really good for the price, and they looked just like the pictures online. The website was easy to navigate when I was picking them out. My only minor complaint was the shipping; it took about 8 days to get to me in Florida, which felt a bit long for fine jewelry. Customer service was responsive when I inquired about the tracking, though. Overall, a solid purchase but next time I'll order with more lead time.
