Great Customer overall service. Please keep in mind which I find out after placing the order, the ring setting you choose must likely are custom-made to order. The are not off the shelf. Because of it, it add around 20-25 days before they can ship your ring out. We submitted payment for our order with confirmation on 8/14 and got the ring in hand on 9/15. In between time, we did emailed few times for follow up. They answer us very quick so there is no delays. That is why I do strongly believe customer service overall is great and awesome. They will send you a copy of the CAD for the setting for approval before they start the job. They will send you pictures and video once they are done. We also find out the lab they used might not be in the US. Since when I went to asked for updates, they told us there is a delayed in custom. The quality is not bad at all, could it been better, of course. That's what happens when you purchased on line without see it or touch it. Worth the price we paid - YES. Shipment packaging is good and safe.

Jenn, thank you so much for taking the time to share such a detailed review. We really appreciate it. ❤️ I’m especially glad you mentioned the communication throughout the process. We know custom jewelry can take a little more time than an off-the-shelf piece, so keeping you updated and making sure you knew what was happening at each stage is something we take seriously. And thank you for being so understanding about the production timeline. We’re really happy to hear you felt the quality made the wait worthwhile. It was a pleasure having you with us, Jenn. Thank you again for trusting Precious Carbon with your order! 💍

Shipping took a little longer than expected. My band is not exactly what I was expecting or what was pictured, the image showed a raised basket so that you would be able to wear a band flush against it. Mine is not raised so I needed to buy a spacer to wear with my wedding band. It’s also not stamped Inside. Communication was good, I did have to reach out for updates a few times during the process, but I always received prompt responses. All and all it is a beautiful ring and I am happy with my purchase.

Hi Heather, Thank you so much for taking the time to share such thoughtful feedback. We’re really happy to hear that you love the ring and that you had a good experience with our communication and customer service. ❤️ We also appreciate you mentioning the fit with your wedding band. Since you were pairing the ring with a band you already owned, the two pieces may not sit completely flush depending on the shape and height of the existing band. If we had known beforehand that you wanted the engagement ring specifically designed to sit flush with your existing wedding band, we would have been happy to take that into consideration during the design process. Your feedback is genuinely helpful to us, and we’ll certainly keep this in mind when helping future customers who are pairing a new ring with an existing band. Thank you again for choosing Precious Carbon, Heather. We’re so glad you’re enjoying your beautiful ring, and we hope you love wearing it for many years to come! ✨ - Team Precious Carbon

The ring was exactly what I ordered and it came out amazing! It's quality and shiny were just as advertised. The only downside it it took a little longer than I was expecting and wanting it to. But it was worth the wait!
