In 1916, Kikichi Mikimoto harvested the very first large lot of cultured akoya pearls in Ago Bay, Japan. These Akoya Pearls were unlike any the entire world had known. These were whole pearls with a mom-of-pearl nucleus developed by a culturing method known as grafting. A small bead was put into the host oyster’s reproductive organ in addition to a little bit of donor mantle tissue – the catalyst of pearl sac creation and nacre deposition – the formation of a pearl.

Today akoya pearls are still a well liked staple in each and every woman’s jewelry collection and the most common kind of pearl sold at fine precious jewelry stores around the globe. They are known for their perfectly circular form, sharp luster, and amazing white-colored body colors with tips of rose and silver overtones.

Choosing a fine strand can be really tricky, however. Not in contrast to gemstones, the caliber of a strand will determine its beauty, durability, and eventually its price. Customers require to understand the Gemological Institution of America’s (GIA) five worth aspects created in 1967, and employed to evaluate the quality of an akoya pearl. These are dimension, form, original appeal, nacre thickness, and surface.


Akoya pearls are often fairly little. The average size is 7 millimeters in diameter, as well as the typical princess length is 17 to 18 inches. Most fall to the size range of three mm to the size of 10 mm. When other value aspects are consistent, larger akoya pearls tend to be more valuable.


While shape is an important value manifestation of other types of cultured pearls like freshwater and Tahitian, akoya pearls are typically really round. This is a result of the flawlessly spherical bead inserted in to the oyster. Nacre is deposited across the bead and many akoya pearl production is circular because of this. Other shapes including symmetrical falls and baroques do occur, but circular pearls are viewed much more valuable.


Luster will be the way of measuring quality and quantity of light reflected from your surface area of a pearl.

These pearls are commonly found on craigslist and ebay as well as in fashion precious jewelry shops for suprisingly low costs. Nevertheless the caveat is the fact these pearls is not going to last, neither will they exhibit a sharp metallic shine. Original appeal and durability are directly linked to the pearl’s nacre thickness.


Cultured pearls would be the only naturally created gemstones on the planet. They do not require to get reduce or polished to show off their beauty, so each will likely be as distinctive as being a snowflake, exhibiting various kinds of growth qualities. These development qualities, no matter how little or how big, are classified as inclusions or imperfections. Because all cultured pearls exhibit some kind of growth characteristic the united states Federal government Trade Commission payment has disallowed the usage of the phrase “perfect” when explaining cultured pearls.

A strand of hanadama grade pearls is just one which has been licensed through the Pearl Science Lab of Japan as exhibiting the very best quality traits in terms of shape, luster, surface area, and nacre thickness.

In order for an akoya strand to become graded AAA all value factors must fall inside the top five percent from the high quality criteria. AAA quality strands are seen as the best, low-hanadama certified strands in the world.

A strand or pearl not meeting the requirements of AAA is just one that falls flat to achieve the top five percent of all the quality requirements. A grade of AA will mean the strand falls in the top 20 percent, along with a quality of AA would then mean the strand drops between grades AA and AAA.

It had been once believed that just those from China had been the finest high quality and most beneficial. Nowadays it is well known that akoya pearls will also be manufactured in Southern Korea, The far east, Vietnam, and even Australia.
