A single pearl with a beautiful turquoise color and iridescent interference colors.
A mysterious baroque pearl with a drop-like form and protrusions.
Since it has a slightly elongated form, we recommend pairing it with hook-type earrings.
※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.
Natural-colored blue Akoya pearls are created when organic components of the shell enter the nacre, creating beautiful interference colors. Since this color occurs accidentally, it is very rare and highly prized when the blue beautifully covers the entire pearl.
Natural-colored blue Akoya pearls are known to be prone to color changes, but "Umihotaru" pearls have thick nacre and deep colors, and undergo a preservation process under a strict management system to prevent color changes.

A collection that offers unique, beautiful, and valuable pearls in screw-type jewelry.
The screw structure allows you to enjoy various base parts such as earrings and rings in combination with pearls freely.
【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 thread part of the screw parts.
※Some parts are untreated.
By coating a thin, elastic film on the screw thread part, the loosening of the screw due to vibration and other factors is suppressed by friction.
However, since it does not lock it, depending on the usage conditions, the screw may loosen.
When using, please wear it after firmly tightening the screw, and check occasionally during wear whether it has loosened to use it with greater peace of mind.
This product uses K18 or Pt900.
Compared to materials such as iron, it is not very hard, so depending on the usage conditions, the screw part may wear out or be damaged.
Please use it carefully so that too much force is not applied vertically 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 plan that can be used as a different piece of jewelry.
Please contact us via the contact page on the website.

・When cleaning the metal parts, please be careful not to touch the screw parts or pearls while polishing.
・If pearls are placed in a high-temperature and humid environment for a long time, they may change color or crack. Please always store them in a place where sunlight does not reach.
・Pearls are soft and prone to scratches. Please store them in a case and in a separate place so that they do not come into contact with other accessories.
