Customer Reviews
Nice ring, a little slow to ship
I got a textured metal ring during their seasonal private sale. The design is unique and the quality of the recycled gold is really evident. It's a beautiful piece that I wear often. The actual creation time for the ring was within what they quoted, which was good. However, after it was finished, it took a few extra days for it to actually ship out, which was a bit frustrating since I was excited to get it. When it did arrive, the packaging was nice and secure. Overall, I'm pleased with the ring itself and it feels like it will last a long time, but the shipping could be a little quicker once the item is ready.
Good value for a special piece
I was looking for an ethical diamond ring and found Harkness. I signed up for their newsletter and got a 10% discount on my first order which was great. The contemporary studs I bought were still a splurge, but with the discount and complimentary shipping, it felt like a worthwhile purchase. It arrived in about a week.
Really happy with my necklace
I ordered a minimalist gold chain from Harkness and it got here pretty fast, like 4 days to reach Denver. It's super delicate but feels strong. I wear it every day now. The online pictures were good but it looks even better in person. Totally happy with it.

do harkness usually have black friday sales? hoping to snag a deal on a necklace for christmas.
can i get a discount for my first order? signing up for the newsletter or something?
Thinking of getting a stacking ring but I'm worried about sizing. do they offer resizing services if I get it wrong?
hey, anyone order a custom engagement ring from Harkness before? wondering what the turnaround time was like. need it by a certain date for a proposal.
Just curious, do Harkness diamonds come with some kind of certification or can you tell if they're legit ethical diamonds?
