For many cultured pearl dealers and wholesalers, the preferred weight measure used for loose pearls and pearl strands is the momme. Momme is a weight measure used by the Japanese for centuries. Today, momme weight is still the standard unit of measure used by most pearl dealers to communicate with pearl producers and wholesalers. One momme corresponds to 1/1000 kan. Reluctant to give up tradition, the Japanese government formalized the kan measure in 1891 as being exactly 3.75 kilograms or 8.28 pounds. Hence, 1 momme = 3.75 grams or 3750 milligrams.

Depending on the waters they’re grown in, pearls can be divided into freshwater pearls and saltwater pearls (which are grown in sea water). There’re generally 3 types of saltwater pearls: Akoya, South Sea and Tahitian. Each pearl type, including freshwater, grows in a specific pearl-bearing oyster species in a unique habitat that is indigenous to certain regions of the world.

When other value factors are equal, the second most valuable shape is near-round, and then followed next in value by other symmetrical shapes like oval, button, drop and baroque. How Pearl Size Impacts Its Value? pearls themselves were a great size, and the colors were very nice. one in each was more oval than round, and one pearl was splotchy in color, almost like it had polka dots on it. Previously, natural pearls were found in many parts of the world. Present day natural pearling is confined mostly to seas off Bahrain. Australia also has one of the world's last remaining fleets of pearl diving ships. Australian pearl divers dive for south sea pearl oysters to be used in the cultured south sea pearl industry. The catch of pearl oysters is similar to the numbers of oysters taken during the natural pearl days. Hence significant numbers of natural pearls are still found in the Australian Indian Ocean waters from wild oysters. X-ray examination is required to positively verify natural pearls found today. Akoya Pearls are the classic, round white pearls that most people are familiar with. They’re mainly cultivated in Japan and China in a saltwater oyster species called Pinctada fucata martensii. Natural Akoya pearls grown in this species are extremely rare.

For pearls of any other shapes, the size is made up of measurements for lengths, widths or depths. Pearl sizes are usually expressed in millimetres and rounded to the nearest 0.5mm.

It is much rarer, for instance, to have a 10mm akoya pearl than a 10mm South Sea pearl. If all the other quality factors are equal, this akoya pearl would command a higher price than the South Sea pearl of the same size.

A well-equipped gem testing laboratory can distinguish natural pearls from cultured pearls by using gemological X-ray equipment to examine the center of a pearl. With X-rays it is possible to see the growth rings of the pearl, where the layers of calcium carbonate are separated by thin layers of conchiolin. The differentiation of natural pearls from non-beaded cultured pearls can be very difficult without the use of this X-ray technique. Despite the common misperception, Mikimoto did not discover the process of pearl culture. The accepted process of pearl culture was developed by the British Biologist William Saville-Kent in Australia and brought to Japan by Tokichi Nishikawa and Tatsuhei Mise. Nishikawa was granted the patent in 1916, and married the daughter of Mikimoto. Mikimoto was able to use Nishikawa's technology. After the patent was granted in 1916, the technology was immediately commercially applied to akoya pearl oysters in Japan in 1916. Mise's brother was the first to produce a commercial crop of pearls in the akoya oyster. Mitsubishi's Baron Iwasaki immediately applied the technology to the south sea pearl oyster in 1917 in the Philippines, and later in Buton, and Palau. Mitsubishi was the first to produce a cultured south sea pearl– although it was not until 1928 that the first small commercial crop of pearls was successfully produced. The correct definition of a South Sea pearl– as described by CIBJO and GIA– is a pearl produced by the Pinctada maxima [20] pearl oyster. South Sea pearls are the color of their host Pinctada maxima oyster– and can be white, silver, pink, gold, cream, and any combination of these basic colors, including overtones of the various colors of the rainbow displayed in the pearl nacre of the oyster shell itself. CIBJO 'Pearl Book' " (PDF). Archived from the original (PDF) on July 23, 2011 . Retrieved July 30, 2010. Regardless of how pearls are formed, whether natural or cultured, most pearls harvested have an average to low quality. Fine quality pearls are very rare. This is largely due to the nature of pearl growth inside the oyster. The oyster secretes nacre slowly to coat the intruder layers after layers. It is the same substance that makes mother-of-pearl, the shiny surface on the inner side of the shell. As an organic gem, these layers of nacre are not always evenly distributed to form a tight structure. Hence the quality varies drastically. In other words, most natural pearls, if found, rarely have qualities that worth a fortune.
