An Exceptionally Gorgeous Antique Genuine Japanese Akoya Pearl Strand Necklace, Art Deco, c.1920, With Fine White Gold Clasp. The necklace is composed of 99 genuine cultured akoya ocean pearls. They are genuine salt water Akoya ocean pearls from a wonderful estate collection. The pearls are very fine quality with gorgeous matched color and a luminous glow that reflects bits of pink in the light. It is quite a process to find as many beautifully matched, round graduated pearls as seen here in this piece. The Mikimoto pearl company often times sold their extra pearls to other pearl companies in Japan. Given the history of these pearls and the high quality, this may very well have been the case. The pearls are graduated from approximately 3 to 7mm. The strand measures approximately 21 inches in length from clasp to pearl end. They date circa 1920 and in lovely estate condition.
