A refreshing, clear blue sea firefly.
Against the deep blue, pink interference colors vividly emerge depending on the angle of the light.
The form is generally rounded, but when viewed from directly above, it is a plump, slightly elongated pearl about 5 mm wide.
Excellent compatibility with stud earrings and fill-gap rings.
※What is a sea firefly (umi hotaru)?
Natural-colored blue baroque Akoya pearls cultivated by one of Japan's leading pearl farms, which has been in business for 120 years in Tsushima, Nagasaki Prefecture.
Only pearls with a mystical blue that seems to reflect the sea of Tsushima are named "sea fireflies" and are certified as a single pearl BRAND.
The beautiful interference colors of Akoya pearls are created when organic components of the shell penetrate the nacre.
Natural blue is an accidental color, so it is rare and extremely precious for it to appear beautifully covering the entire pearl.
Natural-colored blue Akoya pearls are said to be prone to color changes, but "sea fireflies" are pearls with thick nacre and deep color that undergo a preservation process under strict management to prevent color changes.
Those who purchase them will receive a card certifying that it is a sea firefly.

【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 can attach COLLECTIBLE PEARL.
A collection that offers unique, beautiful, and valuable pearls in screw-type jewelry.
The screw structure allows you to enjoy freely combining pearls with various base parts such as earrings and rings.
【Nickel-Free】

The fittings (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 allergy reactions (allergy-free). If you experience any skin abnormalities, discontinue use 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 the screw threads with a thin, flexible film to suppress screw loosening caused by vibration through friction.
However, since it does not lock them, the screws may loosen depending on how you use them.
When using, please fasten the screws securely before wearing them, and check occasionally while wearing them to see if they have loosened, for 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 break depending on how they are used.
Please use it carefully so that too much force is not applied 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 repairs or a remake proposal so that you can use it as a different piece of jewelry.
Please contact us via the contact page on our website.
【Precautions】
・When cleaning the metal parts, please be careful not to touch the screw parts or pearls while polishing.
・If pearls are exposed to high temperatures and humidity for a long time, they may change color or crack. Please always store them in a place away from sunlight.
・Pearls are soft gemstones that scratch easily. Please keep them in a case and store them separately from other accessories.
*Each pearl sometimes has blemishes and flaws on the surface which actually indicate that a pearl is authentic. *For any enquiries and further information about our products, please do not hesitate to contact us before the purchase. *The pearls and jewelries on the image may slightly differ from their actual color, texture and design due to the display resolution on different devices.
