CARE
Professional cleanings at your local jeweler are recommended at least once a year. For a simple way to clean your lab grown diamond jewelry at home, soak it in a bowl of warm water with a few drops of mild dish soap. Use a clean, soft toothbrush to gently scrub away any remaining dirt, especially in hard to reach places like under the diamond or in the basket. Rinse soap off with water and pat dry.
