Thank you for purchasing this product.
In order to enjoy long-term use, please be sure to read this before use.

[Precautions when using]

Alcohol, moisture, cosmetics, dust, sweat, etc. can cause stones and plating to become dull and peel.
If dirt such as sebum adheres to the product, gently wipe it off with a dry, soft cloth (jewelry cloth).
Stones with cleavage properties may break even with the slightest impact.
We recommend putting it in a hard case when carrying it around.

[Storage method]

Some stones have the property of becoming lighter in color (fading) or cracking when exposed to sunlight for a long time.
When storing, please avoid UV rays, extremely dry, and humid conditions, and store in a special case.
Sweat and sebum from pearls, coral, and shellfish can cause them to become cloudy (lose luster).
Wipe gently with a cloth to remove dust.

When storing stones with low Mohs hardness, or stones with low and high hardness at the same time, store them so that they do not rub against each other.

[Daily care]

After use, please remove your jewelry and wipe it gently with a dry, soft cloth (jewelry cloth).
By removing dust, sebum, cosmetics, and other oily dirt from the surface every day, the plating will last longer and prevent dirt from accumulating.

[Places that are easily dirty]

・Gap between stone and metal <br>It's easy to overlook because it's not the front, but please check the whole thing as dirt can easily accumulate in the small grooves on the side.

・Jewelry made with pearls, coral, and shellfish. Gently wipe the surface of the pearl, when the plate and the pearl are in contact with the ground, and between the pearls with a cloth to remove dust.
・Chains, earrings hardware <br>The base of chain necklaces and clip on earring posts is where sweat and sebum can easily collect dirt.
Simply removing dirt with lukewarm water without soaking the stone will make a difference in the plating and shine.

[Home cleaning]

In addition to daily care, we will introduce care that you can do at home.
Try this to remove dirt that cannot be removed with a jewelry cloth or dirt that has accumulated.

・Tools <br>Neutral detergent (kitchen detergent)
Cotton swab Soft cloth (gauze, cotton paper, etc.)
Container, bowl lukewarm water (30-35℃)

・Procedure : Mix lukewarm water and a few drops of neutral detergent in a container.
Soak your jewelry to loosen any dirt.
Use a cotton swab to gently clean the gaps between the stone frame, the back of the ring, and the chain.
*If you rub too hard, it may cause scratches, so please use only stroking force.
Fill a separate container with fresh warm water and rinse the stain.
Gently wipe dry with a soft cloth.
*Make sure it is completely dry before storing it in a jewelry box, etc.

Note: Please be careful by placing a screen or other measures to prevent water from being accidentally flushed down the drain.

[How to care for natural stone]

Warm water...Lukewarm water at 30-35℃...Room temperature waterUltrasonic cleaning...Dry wipe to remove fine dirt using an ultrasonic cleaner...Dry wipe with a soft cloth (chamois leather)
*Mohs hardness and care methods vary depending on the literature.
*We recommend leaving ultrasonic cleaning to a professional who knows the condition of the stone.
*We are not responsible for any damage caused by cleaning at home.

mohs hardness
The hardness of natural stone is expressed as a number from 1 (soft) to 10 (hard).
This indicates the strength against scratches, and does not mean that it is difficult to break.
Materials with a hardness of 4 are easily scratched by cutters and other blades.
You don't need to be too careful in daily life, but please be careful as scratches may occur if it hits something hard or sharp.
Items with a hardness of 5 or higher are less likely to get scratched in daily life.
It is hard enough to be scratched by a knife or other knife.

The breaking of minerals according to their crystal structure is called ``cleavage,'' and refers to the tendency of minerals to break in specific directions.
Cleavage has nothing to do with Mohs hardness, which measures how easily a surface scratches.
For example, diamond is said to be the hardest (hardest to scratch) gemstone on earth, with a hardness of 10, but because it has cleavages in four directions, it is said to be vulnerable to impact from specific directions and easily break.
