This 2-stack channel & diamond round or square ring set is made up of two rings including 1 thick (6mm) channel ring with a 1.5mm diamond and 1 thick (2.5mm) silver ring. This stack is available in sizes 5.0-13.0, including half sizes. Special note: Because of the width of our stack ring sets, it is recommended to buy a stack that is approximately a half to a full size larger than your normal ring size. Materials: Sterling silver (.925), oxidized sterling silver, and a lab-created diamond. All materials are hypoallergenic. We hand carved and oxidized the channel where the diamond is set. The oxidation is protected within the channel and is therefore better preserved over time. We love how the diamond really pops against the oxidized channel. This ring set is handmade in our Upstate New York production studio.

Want to order a ring, but unsure of your size? Order a Ring Sizing Kit before you make a purchase! Choose an approximate ring size range from the drop down menu. Once you place your order, one of our team members will reach out to help you customize your kit and at-home sizing experience. Please allow 1 - 3 weeks for delivery.
When you receive your personalized kit, try on each size. An appropriately sized ring should go over your knuckle easily and it shouldn't feel too constricting when you bend your fingers. It's a good idea to wear the rings at different times of the day as our fingers tend to fluctuate in size. Learn more and watch a video on how to size yourself at home here.
If you're still unsure of your size, send us a photo or video (either via text to 415.637.7762, or email ) and we'll be happy to guide you. We ask that you return your kit within 3 business days. A pre-paid, fully insured label will be included for the return. Once we receive the kit, you can either use the deposit towards your next purchase, or we'll refund the full amount to your card.
