All products are individually handled and handcrafted in studio by Anita Sikma. Each design is a reflection of the designers practice and technique with acute attention to detail, no two pieces are alike. When your not wearing your pieces, keep them stored in a jewelry box and out of sunlight and humidity. Sterling silver will naturally patina over time, this sort of tarnishing can be easily removed with a non abrasive detergent and brush or soft polishing cloth. Anita Sikma uses a blackening solution to intensify the design motif in all her collections, most chemical cleaning solutions will remove the patina the designer has included in her collections, it is important not to use a chemical polishing compound when maintaining the luster of your pieces.
