Customer Reviews
Good ring, slow shipping
I ordered a solitaire engagement ring from Plum Diamonds. The ring itself is beautiful, exactly as pictured, and the lab diamond is very clear. My fiancée loved it. However, shipping took a bit longer than I expected, even with the free shipping option. It wasn't a huge delay, but it would have been nice to get it a few days sooner. Overall, a good experience for a big purchase.
Nice diamond studs
Got some lab grown diamond earrings from Plum Diamonds. They're pretty, not too big, not too small. Look good with everything. Shipping was fine, came in a nice box. No complaints, just a solid pair of studs. Would probably get something else from them down the road.
Great value for a wedding band
I was looking for a men's gold wedding band and found a perfect one here during their anniversary sale. I signed up for their newsletter and got an extra $50 off my first order, which was a nice surprise. The band is solid and comfortable, and the price was much better than other jewelers I checked, especially for recycled gold. It felt like a really smart purchase, and I'm happy with the quality for what I paid.
Detailed custom ring process
I used Plum Diamonds for a custom engagement ring, specifically a hidden halo design with an oval cut lab diamond. The process started with a consultation where I discussed my design ideas and budget. They provided several CAD renderings, and we went through a couple of revisions to get the details just right. The communication from their design team was consistent and helpful, though sometimes it took a day or two to get replies back during busy periods. Once approved, the ring took about five weeks to create and another week for shipping, which arrived securely packaged. The final product is exceptional; the diamond is certified, and the craftsmanship on the setting is very precise. It looks even better in person than the renders. The complimentary resizing was also a useful perk I appreciated.
Absolutely stunning pendant!
Oh my goodness, I just received my lab grown diamond pendant and it is GORGEOUS! The sparkle is incredible. I've been wanting a nice diamond necklace for ages and this one exceeded all my expectations. Plum Diamonds really delivered on quality. I will definitely be back for more jewelry, and I'm telling all my friends about them!

How do Plum Diamonds lab grown compare to something like Brilliant Earth? Quality wise, I mean.
what's their return policy like? if i need to send something back, is it a pain?
Thinking of getting a diamond necklace for my mom's birthday. Does Plum Diamonds do that 'first order' discount thing?
Anyone know if they offer a discount for military folks? My buddy is looking for an engagement ring.
Does Plum Diamonds do free shipping or do I gotta pay extra for that?
