About Jewelry Care
[ About Basic Care ]
If jewelry is left with dirt such as sweat, sebum, sunscreen, or hand cream, it can lead to discoloration and corrosion. After use, please gently wipe it with a soft cloth.
When using a dedicated cloth, please choose one that is suitable for the material. If you want to repair fine scratches, a jewelry cloth with polishing agents is effective, but for jewelry with a matte finish or coating, it may compromise the texture. Please be careful not to over-polish.
[ Care Instructions by Material ]
Our jewelry is made from a variety of materials, including gold, platinum, silver, and natural stones. To ensure that you can enjoy them in beautiful condition for a long time, please handle each material according to its specific characteristics.
Gold (K10/K18/K18 Hard)
- Applying strong force may cause bending or deformation. Please handle with care.
- When sweat and sebum adhere, it is prone to oxidation and discoloration. Please be sure to wipe it off after use. If dirt is difficult to remove,Dedicated clothandCleanerPlease use it to remove dirt.
Platinum
- As it is a relatively soft metal, applying strong force may cause it to bend or deform. Please handle it gently.
If you are concerned about small scratches on the surface, please polish it with a cloth containing a special platinum polishing agent.
Silver
- Due to its very soft metal properties, it may bend or deform. Please handle with care.
- Basically, our silver products are coated on the surface, and discoloration may occur due to oxidation or chemical reactions. In such cases, please use a cleaner specifically designed for silver.
For products that have been treated with K18YG coating, please consult our store.
Diamond
・Due to its very hard nature, it is generally fine to wear it continuously unless it is jewelry with prongs (please be careful not to apply strong impacts).
・Contact with oils from cosmetics or creams can cause a decrease in shine. If this happens, please wipe with a soft cloth. If dirt is difficult to remove,Dedicated CleanerPlease use an ultrasonic cleaner to remove dirt.
Birthstone Jewelry
・Basically, please try to remove them during bathing or household chores as they may cause issues like nail lifting or stone chipping. Feel free to consult us about individual care.
▼Birthstones that require special attention
・Emerald: It has a weak nature against moisture and impact. Ultrasonic cleaners should not be used. Additionally, please avoid using abrasive cleaners and alcohol disinfectants.
・Moonstone/Peridot: They have a relatively weak resistance to shock. Please be careful to avoid dropping them or applying strong force.
・Tanzanite: It has a relatively weak resistance to shock. Please avoid ultrasonic cleaners.
Pearl
- Pearls are organic materials, so they do not have the hardness of stones and are prone to scratches. Please be careful with friction against hard objects.
- It is sensitive to acids (such as sweat), alkalis (such as food and detergents), alcohol, perfumes, creams, etc., so please handle with care. If it comes into contact, please wipe it off immediately with a tissue or a soft cloth.
・After use, please gently wipe with a soft cloth and store it away from moisture, high temperatures, and UV light.
・If there are particularly noticeable stains, please wipe with a soft cloth that has been wrung out with lukewarm water, then dry it off and ensure it is completely dry before storing.
Other Natural Stones
Some items made with natural stones may use adhesive for reinforcement. Please be sure to remove them during exercise or bathing, as exposure to moisture can cause the stones to become loose or detach from their settings.
・When using cleaners that contain abrasives, please be careful to avoid the liquid coming into contact with the stone.
By handling other gemstones according to their specific characteristics, you can keep them in a beautiful condition for a long time. If you have any questions, please feel free to contact us.

About the care of the baby ring commemorative plate
The commemorative plate is made of brass, which has a property of oxidizing when exposed to air.
Where it is touched by hand, sebum remains, and (especially in summer) oxidation may progress quickly. Additionally, even if it is not touched, oxidation will gradually progress over time due to aging.
*From around September 2023, we have been delivering the plates with anti-oxidation treatment on both front and back surfaces.
We have summarized the care methods you can do at home in the blog below. Please take a look if you like.
