Ring Sizer

Caring for a carbon fiber ring is simple and low-maintenance. To clean it, use a soft cloth with mild soap and water, gently wiping the surface to remove dirt or oils. Avoid exposing the ring to harsh chemicals or abrasive materials that could damage the finish. While carbon fiber is strong and durable, storing it in a safe place when not in use can help prevent unnecessary scratches. With proper care, a carbon fiber ring will maintain its sleek appearance for years to come.

Get Your Ring Size Right with Our Ring Sizer

Choosing the right ring size is key to enjoying your carbon fiber ring comfortably and confidently. That’s why we offer an easy-to-use Ring Sizer to help you get the perfect fit the first time around. If the fit isn’t right, no worries—we offer free size exchanges!

Our ring sizer is a 4mm standard width and usually matches up to about 8mm. We recommend adjusting your size based on the width of the ring you plan to purchase. For example, if our sizer gives you a size 9.5 and you’re buying an 10mm or 12mm ring, we suggest going up to a size 10 for the best fit.

Precision Sizing Tips

All of our rings are available in half-size increments to ensure a more tailored fit. While quarter sizes aren’t typically needed, finger size does fluctuate throughout the day due to weather and activity. Follow these tips for the best sizing experience:

A Perfect Fit Should:

• Slide smoothly over your knuckle with minimal resistance
• Rest comfortably when your finger is bent
• Allow easy movement and rotation without applying too much pressure

Additional Sizing Tips:

• Finger sizes vary throughout the day—fingers tend to be slimmer in cooler weather and more swollen during warmer temperatures. The best time to size is in the mid-afternoon.
• Measure multiple times for accuracy before making your purchase.
• Wider rings (10mm or more) tend to fit more snugly, so consider going up by half a size if you’re choosing a wider band.

Our rings are crafted in the USA. We make them to order. Our estimated production timelines for each style are below. 

Pure carbon fiber rings - 0-2 weeks. We often produce these rings quickly with raw materials in stock. 

Metal + carbon fiber - 1-3 weeks. This involves us cutting raw metals and carbon fiber, roughing both sides and permanently bonding them together. The bonding and cutting process takes a little longer. 

Carbon Fiber + Glow - 0-3 weeks. We streamline this process so some styles turn around quick and some take a little longer where we have to raw make luminescent composites.

Carbon Fiber + Precious Metals - 2-4 weeks. Most of our gold is raw cast by our partners in the diamond district in NYC. It takes 1 week for gold to be cast and shipped to us where we use it to work our magic.

Carbon Fiber + Wood - 2-3 weeks. All our wood is stabilized to last and then properly bonded to the carbon fiber for additional durability.
