Experience the Difference of Core Carbon Rings



 Feb 17, 2021

 I LOVE my ring!!! Judy was awesome. Unfortunately my finger must have gained some covid weight because my normal ring size was a bit snug, but Judy took care of it and sent me a replacement. Easy peasy. Thank you so much 😍

My husband hates wearing his cobalt wedding ring but LOVES the carbon fiber ring soooo much! It’s lightweight, comfortable and affordable! We bought a replacement since he lost his original carbon fiber ring and didn’t notice right away … but we found it! So now he has a back up 🙂 All the responses were prompt and like I said, the ring is BEAUTIFUL!

 My husband LOVES his ring! He loves that it’s super light and comfy and never takes it off. He has tapered fingers so he was concerned that it would slip off and hasn’t had any issues.

I ordered the wrong size for my husband and they swapped it out no problem for the correct size. The ring is beautiful, amazing quality, and so light weight!

Our Core Beginnings

All of our rings are handmade in the USA using proprietary processing technology superior to what we originally developed for NASA. We were a composite company first, the rings were created in 2009 when we were unable to find a full carbon fiber ring to purchase. Today our rings are around the world! We love being able to create a one of a kind piece of jewelry. We believe in keeping our prices affordable so everyone has the opportunity to enjoy our craft.
