*Due to the nature of natural stones and device settings, the color of the image may differ from the actual product.

*Size measurements are given for the longest part of each side (length, width, and thickness).
For designs with stones set in bezels or items with bases, the metal parts may also be included in the measurement. Please note that there may be slight discrepancies.

*Most of MONAKA's natural stone items are one-of-a-kind. Items sold in stores may be sold out due to time differences, so please be aware of this in advance. If an item is out of stock, we will contact you within 3 days.

Please handle your jewelry with care, as not only natural stones but also jewelry in general can be damaged if dropped or subjected to strong impacts.

Furthermore, please 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 on and taking off jewelry in soft places such as on a bed or carpet.

Natural stones with low hardness, such as coral, are particularly vulnerable to impact and can easily chip, so please handle them 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 metal discoloration and natural stone deterioration.

If natural stones (especially pearls and opals) are left with moisture or sweat on them, they may deteriorate or discolor. In addition, cosmetics (sunscreen, hand cream, etc.) or chemicals may cause them to lose their luster. After use, please gently wipe them with a jewelry cloth or soft cloth before storing them.

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