【Pearl Details】
SQ (SPECIAL PEARL QUALITY)
| NUMBER: SU58281 | ORIGIN: Tsushima, Japan |
| SHAPE: Baroque | SIZE: aprx.8-9mm |
| COLOR: Blue-green | GRADE [Luster]: Thick |
| GRADE [Luster]: AAA | GRADE [Scratches]: A |
A single pearl with a deep blue-green hue.
From above, the pink interference color is slightly strong, and yellow and other colors can be seen depending on the angle.
Although it is a baroque pearl, the surface is not rough, and it has a shape close to a button shape.
Because growth lines of the pearl can be seen slightly from the setting to the side, the scratch rating is A, but it is not very noticeable.
※What is Umihotaru?
Natural blue baroque Akoya pearls cultured 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.
The beautiful interference colors of Akoya pearls are created when organic components of the shell enter the nacre.
Natural blue color is an accidental color, so it is rare and very precious to appear beautifully covering the entire pearl.
Natural blue Akoya pearls are said to be prone to color changes, but "Umihotaru" isa pearl that has a thick nacre and a deep color, and undergoes a preservation process under a solid management system to make it less prone to color changes.
Those who purchase it will receive a card proving that it is Umihotaru.
You can view an interview article with the producers of Umihotaru here.

【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 not have a metal allergy reaction (allergy-free). If you feel any abnormality 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 thread part of the screw parts.
※Some parts are untreated
It is a treatment that coats a thin, elastic film on the screw thread part to suppress the loosening of the screw due to vibration through friction.
However, because it does not lock it, depending on the circumstances of use, there is a possibility that the screw may loosen.
When using, please wear it after firmly tightening the screw, and checking occasionally during wear whether it has loosened will allow you to 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 circumstances 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, if you contact us, we will propose a repair or a remake plan that can be used as different jewelry.
Please contact us from the contact page of the website.
