Multicolored flexible wearables include a first portion having a first flexible polymer forming a toroid and including one or more colorants, a first surface, a second surface, and a recess in the first surface not reaching the second surface. A second portion formed of a second flexible polymer fills a majority of the recess and includes one or more colorants. The first and second flexible polymers have different colors and are permanently bonded together. Precious material particles may be disposed within the first and/or second flexible polymers. One or more of the colorants may have a color matching a color of the precious material particles. One method of bonding the portions includes depositing a liquid second portion into the recess and then curing it. Another method includes depositing a solid second portion into the recess and then curing a liquid layer of polymer between the first portion and second portion.
