A deep blue-gray base color with a faint pink interference color on the surface, like a firefly at sea.
The form is characterized by a protruding shape that looks like a small bird's beak when viewed from the side.
A charming pearl with its lovely baroque distortion.
It seems to pair well with stud earring and ring base parts, allowing you to enjoy unique and beautiful coordination.
※ What is Umihotaru?
Natural-colored blue baroque Akoya pearls cultivated by one of Japan's leading pearl farms, which has been operating in Tsushima, Nagasaki Prefecture for 120 years.
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.
Natural-colored 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 thick nacre 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 proving that it is a Umihotaru pearl.

【Dedicated Parts】※ Dedicated parts are sold separately. Dedicated parts are here
We offer dedicated rings and earrings made of K18 Yellow Gold or Pt900 that allow you to attach COLLECTIBLE PEARL.
A collection that offers unique, beautiful, and valuable pearls 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 not have a metal allergy reaction (allergy-free). If you notice any abnormalities 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 threads of the screw parts.
※ Some parts are untreated.
By coating a thin, flexible film on the screw threads, the treatment suppresses the loosening of the screw due to friction, such as from vibrations.
However, since it does not lock them, depending on the conditions of use, the screw may loosen.
When using, please make sure to fasten the screw securely 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.
Because it is not as hard as materials such as iron, the screw part may wear out or break depending on the conditions of use.
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.
