A wood ring with a premium core (carbon fiber, ceramic, brass, etc.) some are comfort fit but most of these type are straight walled. Each ring is unique and hand-made some are solid wood that highlight the natural patterns of the grain, others are different species of wood cut thin and glued together making a pattern block which can be cut again and layered in different orientations making the design. We use a mixture of wood (both natural and dyed veneers), metal, and sometimes crushed stones or gems and finish the rings with a resin or CA glue finish for strength, water resistance and polish.
