Ring Sizing Kit

Ready to order a CMD ring but not quite sure of your size? Our personalized Ring Sizing Kit takes the guesswork out of finding the right fit, especially when choosing between our signature round and square shapes or ordering a wider ring stack.

To get started, select your approximate ring size range from the dropdown menu and place your order. A member of our team will reach out to help customize your kit based on the rings you're considering and guide you through the at-home sizing process. Please allow 1–3 weeks for delivery.

Once your kit arrives, take your time trying on the different sizes. A properly fitted ring should slide over your knuckle comfortably, feel secure once it's on, and allow you to bend your finger without feeling overly tight. We recommend trying the rings at different times of day, since finger sizes can fluctuate. For additional tips, including how to measure for individual rings and wider stacks, visit our Ring Sizing Guide.

Still unsure which size feels right? We're happy to help! Send us a photo or video by text at 415.637.7762 or email showroom@colleenmauerdesigns.com, and we'll help you determine the best fit.
