Production Lead Time

All CarbonFi rings are handmade, and crafted per order. We are currently averaging 4-6 weeks of production time for this ring. This timeline is an estimate only and can be advanced or delayed by a variety of factors, including but not limited to material delays or shortages, or labor availability.


We recommend sizing up 1/2 size from your normal ring size to accommodate the extra width of this design for most people. If you're one of the people that have trouble getting rings over your knuckle and then they feel loose, order true to size, this ring will feel a little tighter and you might like the additional width. 

All CarbonFi Rings are sized in US sizes. If you are unsure of your ring size, select the "Unsure - Send Ring Sizer First" size option and we will send you a ring sizer before making your ring. The Cracked Onyx 80/20 is eligible for a free size exchange. If your ring isn't a perfect fit, contact us at, and we will be more than happy to find a solution for you.
