In 1916, Kikichi Mikimoto harvested the first big lot of cultured akoya pearls in Ago Bay, Japan. These Japanese Pearls were unlike any the world had known. They were whole pearls with a mother-of-pearl nucleus created by a culturing method referred to as grafting. A small bead was placed in the host oyster’s reproductive organ along with a little bit of donor mantle tissue – the catalyst of pearl sac creation and nacre deposition – the formation of a pearl.

Today akoya pearls remain a popular staple in every woman’s precious jewelry selection and the most popular kind of pearl sold at fine jewelry stores all over the world. They are known for their flawlessly round form, razor-sharp original appeal, and brilliant white body colors with hints of rose and silver overtones.

Selecting a fine strand can be really tricky, however. Not unlike gemstones, the caliber of a strand determines its beauty, durability, and eventually its price. Customers require to be familiar with the Gemological Institute of America’s (GIA) five value factors created in 1967, and used to assess the caliber of an akoya pearl. These are size, form, original appeal, nacre density, and surface area.


Akoya pearls tend to be fairly little. The normal size is 7 mm in size, and also the typical princess length is 17 to 18 in .. Most fall into the size range of three mm to as large as 10 mm. When all the other value factors are consistent, larger akoya pearls are definitely more beneficial.


While shape is an important worth sign of other kinds of cultured pearls like fresh water and Tahitian, akoya pearls are generally very circular. This is due to the flawlessly spherical bead inserted to the oyster. Nacre is transferred across the bead and most akoya pearl production is circular consequently. Other shapes including symmetrical falls and baroques do occur, but round pearls are considered much more valuable.

Original appeal and durability are immediately correlated to the pearl’s nacre thickness.

Surface area

They do not require to be cut or polished to show away their beauty, so each is going to be as distinctive as being a snowflake, exhibiting various kinds of growth characteristics.

Because all cultured pearls display some form of growth feature the US Federal government Trade Commission has disallowed the utilization of the term “perfect” when explaining cultured pearls.

Even though growth characteristics are globally apparent in cultured pearls, the degree of these qualities is evaluated within the surface quality of the akoya pearl. When all the other grading factors are steady, the fewer imperfections or inclusions visible towards the nude eye, the greater beneficial the pearl.

A – AAA Grading Program

Even though a globally approved grading system for cultured akoya pearls does not presently really exist, there does exist inside the industry best practice standards which use a grading program of A – AAA and hanadama.

A strand of hanadama grade pearls is one which has been licensed through the Pearl Scientific research Laboratory of China as demonstrating the best characteristics when it comes to shape, original appeal, surface, and nacre density.

In order for an akoya strand to get rated AAA all value aspects should fall inside the top five percent in the high quality criteria. AAA quality strands are considered the best, non-hanadama certified strands on the planet.
