The production process of Keshi pearls
Known for their uniqueness and their exceptional beauty, keshi pearls can be produced in controlled environment with human intervention like any normal pearl and finding one in nature is extremely rare. With the development of techniques in the production of cultivated pearls, it is now easy to graft the nucleus into oysters and to create ideal conditions for the formation of keshi pearls.
Pearl farming consists of maintaining and insuring favorable conditions for the production of pearls in order to quality pearls as well as keeping up with market demand. There are several pearl farmers which produce keshi. Their livelihood requires years of experience and knowhow because oysters are extremely fragile to handle. In fact, 10% of oysters die right after grating the nucleus, 10 % in the 3 years that follow and a third only rejects the nucleus which will form a keshi pearl.
Breeding pearl oysters is not limited to one location and can be done wherever in the world. You can get pearls from salt water bred pearl oyster in Tahiti as well as fresh water bred pearl oyster in French Polynesia, Japan, China or even Australia.
The process of obtaining cultivated pearl is long and generally requires between 18 month and 5 years. The time-lapse for producing Keshi depends on various factors such as the location of the farm, the nature of the water (fresh water, salt water lake…) as well as the techniques used during production.
