※About Umibotaru
"Umibotaru" (sea firefly) refers to naturally blue baroque Akoya pearls cultured by one of Japan's leading farmers, established 120 years ago in Tsushima, Nagasaki Prefecture.
Only pearls with a mysterious blue color, as if reflecting the sea of Tsushima, are given the name "Umibotaru" and certified as a unique pearl brand.
Naturally blue Akoya pearls are created when organic components from the oyster penetrate the nacre layer, producing beautiful interference colors. Since this color emerges fortuitously, it is rare and highly prized to find pearls where the blue covers the entire surface beautifully.
While naturally blue Akoya pearls are considered prone to color changes, "Umibotaru" pearls have a thick nacre layer and deep color, and undergo a preservation process under strict management to prevent color changes.
You can read an interview with the producers of Umibotaru pearls here.
