Easy to incorporate into everyday styles, it adds an elegant touch to dressier outfits.
※What is "Umihotaru"?
Natural blue baroque Akoya pearls cultured by one of Japan's leading farmers with 120 years of history in Tsushima, Nagasaki Prefecture.
Only pearls with a mysterious blue, as if reflecting the sea of Tsushima, are named "Umihotaru" and certified as a pearl brand.
The beautiful interference colors of Akoya pearls are created when organic components of the shell enter the nacre layers.
Natural blue colors appear accidentally, so it is rare and very valuable for the color to appear beautifully covering the entire pearl.
Natural blue Akoya pearls are said to be prone to color changes, but "Umihotaru" pearls have thick nacre layers and a deep color, and have undergone a preservation process under strict management to prevent color changes.
Customers who purchase an Umihotaru pearl will receive a card certifying its authenticity.

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

【Nickel-free】

The metal fittings (K18, PT900) are "nickel-free," made without any nickel, which is prone to causing metal allergies.
※This does not guarantee that all individuals will be free from metal allergic reactions (allergy-free). If you experience any skin abnormalities, please stop using the product immediately and consult a specialist.
【Handling of screw parts】

This product features "anti-loosening treatment" on the screw threads of the screw parts.
※Some parts may not be treated.
By coating the screw threads with a thin, elastic film, this treatment uses friction to prevent the screws from loosening due to vibrations, etc.
However, as it does not lock the screw, loosening may still occur depending on how it is used.
When using, please ensure the screw is securely fastened before wearing, and periodically check for any loosening while wearing for peace of mind.
This product uses K18 or Pt900.
Compared to materials like iron, these do not have high hardness, so the screw part may wear out or break depending on usage conditions.
Please be careful not to apply too much vertical force when screwing it on.
Should the screw part deteriorate and become difficult to use, please contact us for repair or a proposal for remaking it into a different piece of jewelry.
Please contact us via the contact page on our website.
【Precautions】
・When cleaning the metal parts, be careful not to touch or polish the screw part or the pearl.
・Pearls may change color or crack if left in a hot and humid environment for a long time. Always store them in a place out of direct sunlight.
・Pearls are soft and easily scratched. Store them in a case, separated from other accessories.
