Its soft form, somewhere between oval and semi-round, blends well with any base part.
From any angle, it's a beautiful pearl with vivid rainbow-like interference colors of yellow and pink floating on a deep blue background.
※What is Umihotaru (Sea Firefly)?
Naturally colored blue baroque Akoya pearls, cultivated by a leading Japanese farmer in Tsushima, Nagasaki Prefecture, with 120 years of history.
Only pearls with a mysterious blue color, 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 of the shell enter the nacre layers.
Naturally occurring blue colors are accidental, so it is rare and very valuable for the color to appear beautifully covering the entire pearl.
While naturally colored blue Akoya pearls are said to be prone to color changes, "Umihotaru" pearls have thick nacre layers and deep color, and undergo a preservation process under strict management to prevent color changes.
Customers who purchase these pearls will receive a card certifying them as Umihotaru.

【Non-Nickel】

The metal fittings (K18, PT900) are "nickel-free," meaning they contain no nickel, which is a common cause of metal allergies.
*This does not guarantee that no one will experience metal allergic reactions (allergy-free). If you experience any skin abnormalities, discontinue use immediately and consult a dermatologist.
【Handling of Screw Parts】

This product features "loosening prevention processing" on the screw threads of the screw parts.
*Some parts may not have this processing.
This processing involves coating the screw threads with a thin, elastic film, which suppresses screw loosening due to vibrations, etc., through friction.
However, as it does not lock the screw, there is a possibility of screw loosening depending on the usage conditions.
When using, please ensure the screw is securely tightened 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 do not have high hardness, so the screw part may wear out or break depending on usage.
Please be careful not to apply excessive upward or downward force when screwing it in.
In the unlikely event that the screw part deteriorates and becomes difficult to use, please contact us for repair or a remake proposal to use it as a different piece of jewelry.
Please contact us via the contact page on our website.
【Notes】
・When cleaning metal parts, be careful not to touch the screw part or the pearl.
・Pearls may change color or crack if left in a high-temperature, high-humidity environment for a long time. Always store them in a place out of direct sunlight.
・Pearls are soft and easily scratched gemstones. Store them in a case, separate from other accessories, to prevent them from touching.
