※What is Umihotaru (sea firefly)?
Natural blue baroque Akoya pearls cultured by one of Japan's leading farmers, established 120 years ago in Tsushima, Nagasaki Prefecture.
Only pearls with a mystical blue, as if reflecting the sea of Tsushima, are named "Umihotaru" and certified as a unique pearl brand.
The beautiful interference color of Akoya pearls is created when organic components from the shell enter the nacre layer.
Natural blue color is an accidental occurrence, making it rare and highly prized to find pearls beautifully covered in this color.
While natural blue Akoya pearls are known to be prone to color changes, "Umihotaru" pearls have a thick nacre layer 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.

【Nickel-Free】

The metal parts (K18, PT900) are "nickel-free" and contain no nickel, which is a common cause of metal allergies.
*This does not guarantee that no metal allergic reaction will occur for everyone (allergy-free). If you experience any skin abnormalities, discontinue use immediately and consult a medical professional.
【Handling of Screw Parts】

This product has "anti-loosening treatment" applied to the screw threads.
*Some parts are untreated
This treatment involves coating the screw threads with a thin, elastic film to prevent screws from loosening due to vibration by increasing friction.
However, it does not lock the screw, so loosening may occur depending on usage.
When using, please ensure the screw is tightened securely before wearing, and periodically check for any loosening during wear to ensure safer use.
This product uses K18 or Pt900.
Compared to materials like iron, these materials are not as hard, so the screw part may wear down or break depending on usage.
Please be careful not to apply excessive upward or downward force when screwing it in.
Should the screw part deteriorate and become difficult to use, please contact us. We can propose repair services or remodeling ideas to transform it into a different piece of jewelry.
Please contact us via the contact page on our website.
【Precautions】
・When cleaning the 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 or high humidity environment for a long time. Please store them in a place out of direct sunlight.
・Pearls are soft and easily scratched. Store them in a case and in a separate location so that they do not touch other accessories.
*Each pearl sometimes has blemishes and flaws on the surface which actually indicate that a pearl is authentic. *For any enquiries and further information about our products, please do not hesitate to contact us before the purchase. *The pearls and jewelries on the image may slightly differ from their actual color, texture and design due to the display resolution on different devices.
