Mikimoto Jewellery


Kokichi Mikimoto's impact on the world of gemmology and jewellery cannot be understated. In 1893, Mikimoto was the first in the world to culture a pearl. Using a 'bead' nucleus within the mollusc, Mikimoto was able to fulfil his dream of "adorning all the women in the world with pearls." Mikimoto patented this innovative culturing technique in 1916, and from this date onwards produced commercial jewellery from the early 20th Century onwards. Still very much in operation and producing an array of breathtaking designs, Mikimoto is responsible for some of the most beautiful and sought after cultured pearl jewellery until the present day. 


Mikimoto Auction Valuations


Mikimoto pearls at auction continue to sell well, despite the large volume of signed and unsigned cultured pearl pieces offered for sale every week. Set apart for the company's significance, the quality of the cultured pearls themselves and Mikimoto's exquisite designs, these pieces possess a timeless style and value.

The highest price achieved for a Mikimoto jewel at auction was the sale of Princess Margaret's Mikimoto pearl and diamond bracelet that sold in 2021 for £320,000. Large beaded necklaces (8mm +) with well-matched and fine quality pearls continue to sell well at auction and command a high premium for their exceptional lustre and size. Elsewhere, modern 14k and 18ct gold, diamond and gem-set Mikimoto pieces with original boxes and Mikimoto paperwork attract a great deal of attention from keen collectors.
