Experience the Difference of Core Carbon Rings



 Dec 16, 2020

My husband loves his carbon ring! The first one did not fit as expected. We even had his finger size verified at 2 different jewelers. I contacted the shop and they made a new ring for him, no questions asked! They even provided postage to send the ring that didn’t fit back. I recommend this shop 100%.

This ring is so beautiful and SO LIGHT. I can barely feel it on my finger and love how the light catches the facets. I wish I could’ve gotten it inscribed with a date. Apart from that tiny point, I would HIGHLY recommend buying from this company 🙂 All the responses were prompt and like I said, the ring is BEAUTIFUL!

I bought this ring with the matte finish for my husband and he LOVES it. So much, that he requested the same ring with a shiny finish for “fancy date nights” 🙂

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.
