*As each item is made by hand using natural stones, there will be individual differences in each piece.

*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.

While there are individual differences, we may have other loose stones in stock. In such cases, we may offer alternatives.

In the unlikely event that you receive a product different from the one you ordered, or a defective product, we will accept returns or exchanges. Please contact us at info@monakajewellery.com.

Please note that returns or exchanges will not be accepted in the following cases:

* Returns/exchanges due to customer convenience
* Products that have been more than 7 days since arrival
* Products that show signs of use
* Products where accompanying items such as boxes and warranty cards have been lost
* Products whose condition is significantly different from when they were delivered

If exchange is not possible due to the item being a one-of-a-kind item or out of stock, we will issue a refund instead.

Please note that in the case of returns or exchanges due to defects or incorrect delivery, we will bear the shipping costs.

Once your payment is confirmed, we will promptly proceed with the production process. Therefore, please note that we cannot accept changes to your order details, such as alterations to the length, size, or material of custom-made items.

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.
