Product Details

The Ultra carbon fiber ring is made out of 100% real carbon fiber, with no added metal of any kind...making it extremely unique.  You will be amazed by how little it weighs.

This ring is a little less than 1/4" wide or slightly wider than 6mm across its face. The ring takes on a standard 2x2 twill weave but is simply rotated 45-degrees, giving it a completely different look.  It has a polished finish giving a semi-gloss look with a very durable surface. No coatings are used on the rings, each one is individually wet sanded through 10 stages of sanding with a final application of buffing compound.

Amazing Rings & Customer Service!

These rings are perfect! They are so light you can’t even tell it’s on your finger. The Carbon Fiber is great quality and it looks great. If you are a woman buying this ring I suggest going up half a size. I am a 5 1/2 but, it was a little too small and I’m getting a size 6 instead. The costumer service is outstanding which made my experience even better. My fiancé loves the ring I got him, I ordered his usual size and it fits him perfectly and he loves how light it is. I highly recommend buying from this company!

Ultra Carbon Fiber Ring - Forty Five Narrow / Polished

Lightweight!!! True to size and excellent quality. Though a little pricey, but a lot better than what's available on Amazon in pure carbon. A good ring for the daily activities (I'm in construction) and a night on the town.

Recieved wrong item, but excellent Customer Service

I ordered the narrow 6mm Forty Five ring, but recieved the wider version (almost 10mm). It took a exactly 3 weeks from ordered to delivered and it looks fantastic! The Customer Sercice communication thru Facebook Messenger is outstanding and my replacement is being rush delivered with free return shipping.

Beautiful ring

I am very pleased with our purchase and the customer service at Carbon Fiber Gear. We had to exchange the ring for a smaller size and it was an easy process. The ring is beautiful and we couldn’t be happier!

Hubby’s wedding ring

Hubby and I more than overjoyed to have received his ring. He had the exact ring for our wedding and mysteriously lost it after our one year anniversary. Luckily, Carbon Fiber Gear still had the ring available. Thank you to all at Carbon Giber Gear
