Stunning…

I am a huge sucker for carbon fiber. As such, I’ve had numerous items of different sorts and this ring is a fantastic piece! The workmanship is second to none. If I had one complaint, it fits a bit smaller than my other wedding band that is supposedly the same ring size. That said, I cannot bring myself to return it. It really is that stunning… Chance’m, you won’t be disappointed!

Great ring

This ring is great, had several compliments on it and it is very light. Fits awesome, looks fantastic. Highly recommend this ring to anyone looking for something like this!

Awesome Product & Company

This company does go above and beyond to ensure you’re a happy customer to return! I will definitely be recommending this company to anyone looking for a reasonable priced ring for the best quality! I did receive the wrong ring at first but I was able to speak with Dave and he was able to get my new ring made for me as quick as they could and get it shipped to me. I honestly was so upset about the wrong ring but the way they handled the situation was AMAZING and QUICK!! Definitely look at them for your next purchase! Their rings are amazing quality and I would buy from here again!

Awesome ring and amazing service!

What a great experience! My husband loves his ring.

Love the ring!

My fiancé loves carbon fiber, the hood of his car is even carbon fiber. We were thrilled to come along this website! We just received the ring and we both love it. It's light weight and the detailing on it is great!

Great product and customer service centered!

I made a mistake when ordering because I needed it by a specific day. And the team went above and beyond to compensate for my mistake and made sure that everything went perfectly. I highly highly recommend this product and company!

Beautiful and unique

Well worth the price and the wait for having it made. It is eye catching and my friends can't believe how light weight it is. This would make a great gift

Great looking ring

Strong, light weight, hasn't broken, looks amazing!

Great product

Husband loved it. Great product. Was worried on the timing and they were great help.

Ring looks awesome

Took a little while to make but is true to size and looks great! I hope it holds up but I suspect that it will.
