14k Solid Gold—Gold is a naturally soft material. Subtle marks will appear over time, embodying your many moments lived. Clean with warm water, mild dish soap and a soft-bristled toothbrush. Polish gently with a soft cloth.

Diamond—Clean regularly with warm water, mild dish soap and a soft-bristled toothbrush. Avoid chemicals. Store with care. We recommend annual professional cleanings to avoid loosening of the diamond’s setting due to buildup.
