※About Umihotaru (Sea Firefly)
These are natural blue baroque Akoya pearls cultivated by one of Japan's leading farmers, with 120 years of history, in Tsushima, Nagasaki Prefecture.
Only pearls with a mysterious blue color, as if reflecting the sea of Tsushima, are given the name "Umihotaru" and certified as a pearl brand.
Natural blue Akoya pearls are created when organic components from the oyster penetrate the nacre layer, producing beautiful overtones. Since this color appears accidentally, it is rare and very valuable for the blue to cover the entire pearl so beautifully.
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 minimize color changes.

【Specialty Parts】※Specialty parts are sold separately. Specialty parts are here
We offer special rings, earrings, etc., made of K18 Yellow Gold or Pt900, to which COLLECTIBLE PEARL can be attached.
A collection that offers unique, beautiful, and valuable pearls in screw-type jewelry. The screw mechanism allows for free combinations of pearls with various base parts such as earrings and rings.
【Nickel-Free】
The metal fittings (K18, PT900) are "nickel-free," made without any nickel, which commonly causes metal allergies.
※This does not guarantee that no one will experience a metal allergic reaction (allergy-free). If you experience any skin abnormalities, please discontinue use immediately and consult a dermatologist.
【Handling of Screw Parts】
This product features a "loosening prevention" treatment on the screw threads.
※Some parts are untreated
This process involves coating the screw threads with a thin, elastic film to prevent screws from loosening due to vibration, etc., through friction.
However, it does not lock the screw, so there is a possibility that the screw may loosen depending on the conditions of use.
When using, please ensure the screw is securely fastened before wearing, and periodically check during wear to ensure it has not loosened for safer use.
This product uses K18 or Pt900.
Compared to materials like iron, these metals have lower hardness, so the screw part may wear down or break depending on usage conditions.
Please be careful not to apply excessive force up or down when screwing it in.
In the unlikely event that the screw part deteriorates and becomes difficult to use, please contact us for repair or suggestions for remaking it into a different piece of jewelry.
Please contact us via the contact page on our website.
