On light-colored surfaces such as skin or white, it has a base color of turquoise, but on dark clothes such as black, it takes on reddish interference colors, changing the impression of its appearance.
Its glossy luster is beautiful from every angle, and its drop-like form is perfectly suited for hook-type earrings or charms.
※What is Umihotaru?
Natural-colored blue baroque Akoya pearls cultivated by one of Japan's leading pearl farms, which has been operating 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 layer.
Natural-colored 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" is a pearl that has a thick nacre layer and a deep color, and undergoes a preservation process under a strict management system to prevent color changes.
Those who purchase it will receive a card proving that it is Umihotaru.

【Nickel-Free】

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 not have a metal allergy reaction (allergy-free). If you feel any abnormality on your skin, please stop using it immediately and consult a specialist.
【Handling of Screw Parts】

This product has a "loosening prevention treatment" applied to the screw thread part of the screw part.
※Some parts are untreated
It is a process that coats a thin, elastic film on the screw thread part to suppress the loosening of the screw due to friction, such as vibration.
However, since it does not lock it, depending on the conditions of use, there is a possibility that the screw may loosen.
When using, please wear it after firmly tightening the screw, and checking 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 the conditions of use, the screw part may wear out or break.
Please use it carefully so that too much force is not applied up and down when turning 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 via the contact page on the website.
