Customer Reviews
Love my new Skydiamond earrings!
Compared to Brilliant Earth, Skydiamond's prices were really competitive, especially after I used that 15% off code for new subscribers. My ethical diamond earrings are stunning! Only tiny thing is I wish they offered free delivery on all orders, not just over a certain amount.
My go-to for ethical jewelry
This is my third purchase from Skydiamond, and once again, they didn't disappoint. I've bought earrings and a pendant before, and this time it was a tennis bracelet. Their consistent quality is why I keep coming back. The bracelet is just as beautiful as my previous pieces, and the ethical aspect is a huge plus for me. Delivery was quick, arriving in 4 days, same as my last order. It's great to know I can rely on them for high-quality, sustainable jewelry every time.
Beautiful solitaire ring
I just received my solitaire engagement ring and it's absolutely gorgeous! The diamond sparkles so much. The whole experience, from browsing to delivery, was fantastic. I'm telling all my friends about Skydiamond. I'll definitely be buying from them again!
Good value for a lab diamond
I bought a pair of diamond stud earrings during a seasonal sale. I was looking for something ethical that wouldn't break the bank. The discount made it feel like a really good deal. The earrings are well-made and definitely sparkle. It felt like I got a high-quality product for a fair price. Shipping was free, which helped the overall value too. Worth it for sure.
Nice wedding band
Got a white gold wedding band here. It came pretty fast, like 6 days or so. It looks good and fits perfectly. My wife likes it too. The whole thing was easy enough. No complaints, really.
Halo ring purchase experience
I ordered a halo engagement ring last month. The website was easy to navigate and placing the order was straightforward. Delivery took about a week, which was reasonable, and the ring arrived securely packaged. The diamond itself is stunning, and the craftsmanship of the recycled gold setting is excellent. I had a question about certification, and customer support responded within a day with all the details. It was a smooth process overall, and the quality lives up to the promise.
Skydiamond Community Discussion
Share tips, ask questions & help fellow shoppers save more
Hey everyone, thinking about getting an engagement ring from Skydiamond. Anyone know about their return policy, especially for rings?
Are Skydiamonds really, like, real diamonds? Or are they more like moissanite or something?
I want to get a ring but might need to resize it. Is that something Skydiamond does, or do I have to take it to a local jeweler?
do skydiamonds come with any kind of proof they're real? like a certificate or anything?
Quick question on shipping. How long does it usually take for Skydiamond stuff to arrive in the US? I'm in New York.
