Jewelry, including natural stones, can be damaged if dropped or subjected to strong impacts, so please handle with care.

Furthermore, refrain from wearing jewelry when doing housework, bathing, sleeping, carrying heavy loads, or playing sports, as this may lead to deformation or damage to the jewelry, or unexpected injuries.

Broken natural stones cannot be repaired, so we recommend putting them on in a soft place, such as on a bed or carpet.

Natural stones with low hardness, such as coral, are particularly vulnerable to impact and chip easily, so please handle with extreme care.

Avoid long-term storage in direct sunlight or in dry, hot, and humid environments, as this may cause deterioration or discoloration.

Also, please refrain from wearing the jewelry in seawater or hot spring water, as these may cause discoloration of metals and deterioration of natural stones.

Natural stones (especially pearls and opals) may deteriorate or discolor if left with moisture or sweat on them. Cosmetics (sunscreen, hand cream, etc.) and chemicals may also cause loss of luster. After use, please gently wipe the jewelry with a jewelry cloth or soft cloth before storing it.

Jewelry can easily scratch each other and may break if they come into contact. When carrying, store them in a jewelry case so they are not crushed. For storage at home, we recommend using a tray or a case with individual compartments.
