About Jewelry Care

[ About Basic Care ]
If jewelry is left with sweat, sebum, sunscreen, hand cream, or other dirt on it, it can cause discoloration and corrosion. After use, gently wipe it with a soft cloth.

When using a dedicated cloth, please choose one suitable for the material. If you want to repair fine scratches, a jewelry cloth with abrasive is effective; however, for jewelry with a matte finish or coating, it may damage the texture. Please be careful not to over-polish.


[ About Care by Material ]
Our jewelry uses a variety of materials such as gold, platinum, silver, and natural stones. To keep them beautiful and in good condition for a long time, please handle each material according to its specific properties and characteristics.

Gold (K10/K18/K18 Hard)
・Applying strong force may cause deformation or damage. Please handle with care.
・When sweat or sebum adheres, oxidation can occur, making discoloration more likely. Be sure to wipe it off after use. If dirt is difficult to remove,Dedicated clothyaCleanerPlease use it to remove dirt.

Platinum
・Since it is a relatively soft metal, applying strong force may cause deformation or damage. Please handle it gently.
・If you are concerned about small surface scratches, please polish with a cloth containing a platinum-specific polishing agent.

Silver
・Because it is made of very soft metal, there is a risk of deformation or damage. Please handle it gently.
・Basically, our silver products are coated on the surface, so discoloration due to oxidation or chemical reactions may occur. In such cases, please use a silver-specific cleaner.
・For products with K18YG coating, please consult our store.

Diamond
・Because it is a very hard stone, it is basically fine to wear it continuously unless it is jewelry with prong settings (please be careful not to apply strong impact).
・Contact with oils from cosmetics or creams can cause a loss of shine. If it comes into contact with these, please wipe it with a soft cloth. If the dirt is difficult to remove,Dedicated CleanerPlease use an ultrasonic cleaner to remove dirt.

Birthstone Jewelry
・Basically, please remove it as much as possible when bathing or doing housework. It can cause damage such as nail lifting or stone cracking. Please feel free to consult us about individual care.

▼ Birthstones that require special attention
・Emerald: It is sensitive to moisture and impact. Do not use ultrasonic cleaners. Also, avoid using cleaners with abrasives or alcohol disinfectants.
・Moonstone/Peridot: These are relatively fragile and sensitive to impact. Please be careful not to drop them or apply strong force.
・Tanzanite: It is relatively fragile and sensitive to impact. Avoid using ultrasonic cleaners.

Pearl
・Since pearls are organic materials, they do not have the hardness of stones and are easily scratched. Please be careful to avoid friction with hard objects.
・They are sensitive to acids (such as sweat), alkalis (food, detergents, etc.), alcohol, perfume, and creams, so please handle them with care. If they come into contact, wipe them off immediately with tissue or a soft cloth.
・After use, gently wipe with a soft cloth and store them avoiding dryness, humidity, high temperatures, and ultraviolet rays.
・If dirt is particularly noticeable, wipe with a soft cloth dampened with lukewarm water and wrung out tightly, then dry thoroughly with a dry cloth before storing.

Other Natural Stones
・Some items using natural stones are reinforced with adhesive. Please be sure to remove them during exercise or bathing, as exposure to moisture can cause the stones to loosen or detach from their settings.
・When using cleaners containing abrasives, please be careful to avoid letting the liquid come into contact with the stones.

For other gemstones as well, proper care according to their individual characteristics will allow you to use them beautifully for a long time. If you have any concerns, please feel free to contact us.

About the care of the baby ring commemorative plate

The commemorative plate is made of brass, which naturally oxidizes when exposed to air. In some cases, discoloration or spots may appear even at the time of delivery. Please understand that this is due to the inherent properties of brass.
Areas touched by hand may retain skin oils, which can accelerate oxidation (especially during summer). Even if the plate is not touched, gradual oxidation will occur over time due to aging.
*Since around September 2023, we have been applying an anti-oxidation coating to both sides of the plate before shipping.

We have summarized care instructions you can do at home in the blog below. Please take a look if you are interested.

If the above methods do not restore the plate's appearance, we can polish it for you at our shop (free of charge; you only need to cover round-trip shipping costs). If you would like this service, please contact us using the link below.
