Care Instructions

Neptune jewelry is handmade from high quality metals and stones. Each piece is expertly crafted by artisans to last and be worn everyday. No extra treatment or care is necessary. Jewels and metals may be polished if the collector chooses to do so, but it is not required. This can be done effectively with a toothbrush and toothpaste.
