Q: How do I care for my gemstone jewelry?
A: Our brand's jewelry uses a lot of natural, delicate stones.
Due to its characteristics, it may be prone to cracking if subjected to strong impacts or sudden temperature changes. Please handle with care.
In addition, the stones and metal parts may become discolored or cloudy if they come into contact with sweat, sebum, cosmetics, etc. After use, we recommend that you wipe them lightly with a soft cloth and store them in a place away from direct sunlight, high temperatures, and humidity.
Some types of stone are sensitive to water and detergent, so please remove them when bathing, doing water work or playing sports, and handle them gently in your daily life.
