※What is "Umihotaru"?
Natural color blue baroque Akoya pearls cultured by a leading Japanese farmer with 120 years of history in Tsushima, Nagasaki Prefecture.
Only pearls with a mysterious blue, as if reflecting the sea of Tsushima, are named "Umihotaru" and certified as a single pearl BRAND.
The beautiful interference colors of Akoya pearls are created when organic components from the shell enter the nacre layers.
Natural blue colors appear accidentally, so it is rare and very valuable for the color to appear beautifully covering the entire pearl.
Natural blue Akoya pearls are said to be prone to color changes, but "Umihotaru" pearls have thick nacre layers and rich color, and have undergone a preservation process under strict management to prevent color changes.
Customers who purchase these pearls will receive a card certifying that they are Umihotaru pearls.

【Nickel-Free】

The metal fittings (K18, PT900) are "nickel-free," made without any nickel, which is a common cause of metal allergies.
※This does not guarantee that everyone will be free from metal allergic reactions (allergy-free). If you experience any skin abnormalities, discontinue use immediately and consult a medical professional.
【Handling of Screw Parts】

This product has a "loosening prevention treatment" applied to the screw threads.
※Some parts are untreated
By coating the screw threads with a thin, elastic film, this treatment suppresses screw loosening due to vibration, etc., through friction.
However, as it does not lock, screws may still loosen depending on the usage conditions.
When using, please ensure the screw is securely fastened before wearing, and periodically check for any loosening during wear for safer use.
This product uses K18 or Pt900.
Compared to materials like iron, these are not as hard, so the screw parts may wear out or be damaged depending on usage.
Please be careful not to apply excessive force vertically when screwing the parts.
In the unlikely event that the screw part deteriorates and becomes difficult to use, please contact us. We can propose repair or a remodeling plan to use it as a different piece of jewelry.
Please contact us via the contact page on our website.
【Precautions】
・When cleaning metal fittings, be careful not to touch the screw parts or pearls.
・Pearls may change color or crack if left in a high temperature and humidity environment for a long time. Always store them in a place out of direct sunlight.
・Pearls are soft and easily scratched. Store them in a case separately from other accessories.
