With a perfect size of 7–8 mm, they pair well with hook-type earrings.

In addition to being worn as earrings, these pearls can be enjoyed in arrangements unique to a pair, such as using them separately for a ring or charm.
※What is Umihotaru?
Natural-colored blue baroque Akoya pearls cultured 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 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 blue is an accidental color, so it is rare and extremely precious when it appears beautifully covering the entire pearl.
Natural-colored blue Akoya pearls are said to be prone to color changes, but "Umihotaru" pearls have a thick nacre layer 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 they are Umihotaru.

【Exclusive Parts】※Exclusive parts are sold separately. Exclusive parts are here

A collection of unique, beautiful, and valuable pearls offered in screw-type jewelry.

【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 be free from metal allergies. If you experience any skin abnormalities, please stop using it immediately and consult a specialist.
【Handling of Screw Parts】

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 treatment uses friction to suppress the loosening of the screws caused by vibrations and other factors.
However, since it does not lock them, the screws may still loosen depending on how you use them.
When using, please tighten the screws securely before wearing them, and check occasionally while wearing them to see if they have loosened, so that you can use them with greater peace of mind.
This product uses K18 or Pt900.
Because it is not as hard as materials such as iron, the screw parts may wear down or become damaged depending on how they are used.
Please be careful not to apply too much force vertically when tightening the screws.
If it becomes difficult to use due to deterioration of the screw parts, 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 our website.

・When cleaning the metal parts, please be careful not to touch the screw parts or pearls while polishing.
