Akoya Pearls

Japanese Akoya pearls are the original cultured pearl from which all other pearl farming developed. For almost one hundred years, their simple, yet beautifully lustrous presence has captivated and adorned stylish women all over the world.


Nestled in the sheltered coast lines of Japans island southern peninsulas.

Japanese Archipelago

A century of pearl farming has been carried in the waters of Japans “Shimas” or Peninsulas with The most famous of these probably being Ago Bay in Mie Prefecture,. It was here at the end of the Nineteenth century through painstaking trial and error, a suscessful technique of pearl cultivation was eventually developed. Today, other areas such as the Uwe coast in Ehime peninsular and the Kujukushima Islands off the coast of the Saiki National Park are important Akoya pearl producing areas.

Akoya Pearl Grading

Pearls, being products of organic nature like ourselves, vary greatly in their finish and appearance. In order to make sense of the variance of quality coming on to the market, grading systems have been introduced to try and create some order and regularity for buyers.


Lustre is the quality of reflected light from the pearl, and is generally thought of as its shine or brightness. The thicker the layers of nacre that build on a pearl, the deeper the lustre and more attractive the pearl will appear.

Surface Quality

Surface quality relates to the presence of imperfections, pits or blobs on the face of the pearl. Total absence of any imperfection is the ideal standard.


As a rule, a perfect round shape is considered most desirable. Shapes can deviate from perfect round by many degrees, with each degree reducing the perceived value of the pearl. The antithesis of the round pearl is the semi baroque or baroque pearl with its free form outline. The exception to the above is that of perfect pear or drop shapes which are highly desirable as matched pairs for earrings. It must also be remembered that while commercially not as valuable, some adore the organic, individuality of baroque or semi baroque pearls.


Colour in pearls is a matter of either pure body colour or overtones of body colours.
In non-white pearls such as Tahitian and Gold South Sea Pearls, the strength of colour is seen as a positive value factor.
While with white Akoya pearls the overtone tint of the pearl-most often pinky white, is considered to be the most attractive. It must be remembered however, that the wearers own skin tone and personal taste will have the ultimate judgement on colour choice.

Akoya Pearl Sizes

Akoya pearls generally range in size from as small as 2.5 mm to as large as 11mm. Akoya pearls below 5.0 mm are typically considered small in size. 5.0 mm to 9.0 mm are generally the more popular sizes selected for necklaces,

Grading System

Unfortunately, there is no one standardised system for pearl grading, however the trade has generally adopted a system of appellation based on using the letter 'A', very much as the hotel trade uses stars to represent quality of accommodation. This has resulted in some using 'AAA' as their top grading while other use 'AAAAA' as theirs, so the situation can be somewhat confusing. To make matters more complicated the Tahitian pearl farmers use a system of 'A-D', with 'A' being the highest grade.

For simplicity at Pearl Gallery we have decided to unify our systems as 'A-AAA', with between grades marked as '+', so for example 'AA+' is between 'AA' and 'AAA', with 'AAA' being our top grade.

The exception to this is the Hanadama grade Akoya Pearls which are laboratory certified in Japan as being amongst the best quality in the harvest.
