This pearl has a drop-like baroque form and is a small-sized Umihotaru, measuring approximately 6.9 mm in width and 7.7 mm in height.
It is a single pearl with a faint pink interference color within its turquoise hue, concealing depth and delicate beauty within its soft glow.
Understated yet striking, it adds a subtle touch of glamour to everyday life.
※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 from 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 known to be prone to color changes, but "Umihotaru" pearlshave thick nacre layers and deep colors, and undergo a preservation process under strict management to prevent color changes.
Those who purchase them will receive a card certifying that it is a Umihotaru pearl.

【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.
This treatment involves coating a thin, flexible film 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 loosen depending on how it is used.
For safer use, please tighten the screw securely before wearing it and check occasionally while wearing it to ensure it has not loosened.
This product uses 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 the screw part deteriorates to the point where it becomes difficult to use, please contact us, and we will offer a repair or a remake plan so that it can be used as a different piece of jewelry.
Please contact us via the contact page on our website.
【Precautions】
・When cleaning the metal parts, please polish them carefully without touching the screw parts or the pearl.
・If pearls are exposed to high temperatures and humidity for an extended period, they may change color or crack. Please always store them in a place away from sunlight.
・Pearls are soft gemstones that scratch easily. Please store them in a case and in a separate location away from other accessories.
