Natural-colored blue baroque Akoya pearls cultured by one of Japan's leading pearl farms, which has been in business for 120 years in Tsushima, Nagasaki Prefecture.
Only pearls with a mystical blue that seems to reflect the sea of Tsushima are named "Umihotaru" and are certified as a single pearl BRAND.

The beautiful interference colors of Akoya pearls are created when organic components of the shell enter the nacre.
Natural blue is an accidental color, so it is rare and extremely precious for it to appear beautifully covering the entire pearl.

Natural-colored blue Akoya pearls are said to be prone to color changes, but "Umihotaru" pearls havethick nacre and deep color, and undergo a preservation process under a strict management system to make them less prone to color changes.

Those who purchase them will receive a card proving that it is Umihotaru.

The metal parts (K18, PT900) are "nickel-free," made without any nickel, which is known to cause metal allergies.

※This does not guarantee that everyone will be free from metal allergies (allergy-free). If you experience any skin abnormalities, please stop using it immediately and consult a specialist.

This product has a "loosening prevention treatment" applied to the screw threads of the screw parts.
※Some parts are untreated.
By coating a thin, flexible film on the screw threads, the loosening of the screw due to vibration and other factors is suppressed by friction.
However, since it does not lock the screw, depending on how you use it, the screw may loosen.
When using it, please make sure the screw is securely fastened before wearing it, and check occasionally while wearing it to see if it has loosened, so that you can use it with greater peace of mind.

This product uses K18 or Pt900.
Compared to materials such as iron, it is not as hard, so depending on how you use it, the screw part may wear out or break.
Please be careful not to apply too much force vertically when tightening the screw.
If it becomes difficult to use due to deterioration of the screw part, please contact us, and we will offer a repair or a remake proposal so that you can use it as a different piece of jewelry.
Please contact us through the contact page on the website.
