Hanadama, meaning Flower Pearl, represents the highest quality available in Japanese Akoya Pearls, certified by the Japan Pearl Science Laboratory. Only approximately 2% of the annual Akoya cultured pearl harvest qualifies for the Hanadama Grade. This beautiful Akoya pearl necklace is the largest pearl size available in Akoya pearls, and ranges between 9.5-10mm in size and consists of all beautiful and extremely lustrous Hanadama pearls.
