Product Care:

Each piece of our jewelry is hand-crafted and therefore delicate. Please use appropriate care to enjoy our jewelry for a long time. The majority of our collections consist of 14k gold fill and sterling silver & can be cleaned with a polishing cloth or jewelry cleaner. Please note that 14k gold fill and sterling may darken or tarnish with normal wear. We recommend gently wiping the metal surface with a polishing cloth. CMD offers life-long cleanings on all of our jewelry as well as chain replacements, which range from $25 – $40. Oxidized (black) silver jewelry may lighten in color over time. If you buy an oxidized piece, please know that oxidation fades over time, especially when friction is applied. Would you like your jewelry piece re-oxidized? No problem. Simply email info@colleenmauerdesigns.com or call 415.637.7762 to make an appointment.
