※What is Umihotaru?
Natural-colored blue baroque Akoya pearls cultivated by one of Japan's leading farmers, which has been operating for 120 years in Tsushima, Nagasaki Prefecture.
Only pearls with a mysterious blue that seems to reflect the sea of Tsushima are named "Umihotaru" and are certified as a single pearl BRAND.
Natural-colored blue Akoya pearls are created when organic components of the shell enter the nacre, creating beautiful interference colors. Since it is an accidental color, it is very rare and precious for the blue to appear beautifully covering the entire pearl.
Natural-colored blue Akoya pearls are said to be prone to color changes, but "Umihotaru" isa pearl with a thick nacre and deep color, which undergoes a preservation process under a solid management system to make it less prone to color changes.
