Only pearls with a mystical blue that seems to reflect 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 layer.
Natural-colored blue is an accidental color, so it is rare and extremely precious for it to appear beautifully across the entire pearl.
Natural-colored blue Akoya pearls are said to be prone to color changes, but "Umihotaru" pearls have thick nacre layers and deep colors, and undergo a preservation process under a strict management system to prevent color changes.
Those who purchase them will receive a card certifying that they are Umihotaru pearls.

【Handling of Screw Parts】

This product has a "loosening prevention treatment" applied to the screw threads of the screw parts.
※Some parts are untreated.
A thin, flexible film is coated on the screw threads to suppress screw loosening caused by vibration and other factors through friction.
However, since it does not lock the screw, the screw may still loosen depending on how it is used.
When using it, please tighten the screw securely before wearing it, and check occasionally while wearing it to see if it has loosened, for greater peace of mind.
This product is made of K18 or Pt900.
Because it is not as hard as materials such as iron, the screw part may wear down or become damaged depending on how it is used.
Please use it carefully so that too much force is not applied 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 repairs or a remake proposal so that it can be used as a different piece of jewelry.
Please contact us via the contact page on our website.
