Customer Reviews
Nice ring, long wait
I ordered a custom hidden halo ring. The design process was pretty smooth online. The ring itself is beautiful, exactly what I wanted. My only real minor gripe was the wait time; it took about five weeks to get here. I know custom takes time, but I was checking the tracking every day. Customer service was helpful when I called, though. Overall happy with the purchase.
Reliable for eternity bands
This is my third purchase from Plum Diamonds, usually for gifts or upgrades. I got an eternity band this time, and it was just as expected. Their quality is consistent, and the lab diamonds always sparkle nicely. Shipping was quick to Florida, arrived in about a week. I keep coming back because I know what I'm getting, and they've never let me down. Good selection of bands too.
Good value overall
I was looking for a lab-grown diamond pendant and saw they had a first-order discount. Got a nice solitaire pendant for less than I expected. Shipping was free and it arrived sooner than I thought. Definitely felt like I got a good deal.
