VK Designs is a fantastic jewelry shop in Portland, Oregon, and I've been lucky to offer some of my ring boxes with their work. The latest commission was for 20 small ring boxes stained jet black, both single & double ring sizes. They were gracious enough to post information about the boxes and here's a link to their blog. If you're in the Portland area, be sure to contact them for an appointment to view their work. It's all handmade using recycled materials and free-trade gemstones.
