Do you know, for a gemologist, it is very easy to distinguish diamond from zircon only by distinguish their adamantine luster and sub-adamantine luster with unaided eye? Their luster look the same in your eyes, right? But the tiny difference between adamantine luster of diamond and sub-adamantine luster of zircon shows a strong identified clue for trained eye. They looks do really different under trained eye, which means totally different types of gemstone and various market prices. The reason is the same for why luster of pearls looks similar but cost totally differently.
The luster of a pearl is one of the quality factors for a pearl and it is the most important of all the value factors to the beauty of a pearl. Both natural and cultured pearls are composed of crystalline layers from which lights is reflected at the near the surface. The luster of cultured pearls with a nucleus depends on nacre thickness and the surface characteristics. More than 90% of all pearls with good nacre thickness and slight growth characteristics will show a good to high luster.
The nacre thickness is indicated by the length of the time that a pearl is kept in the mollusk. The longer it is kept in the mollusk, the thicker of the pearl nacre and the larger size of the pearl will be.
The nacre growth rate depends on water temperature, the time of the year and the time of the day. For example, the Akoya cultured pearl-producing oyster from the Ago Bay in Japan, produces an average layer of 0.15mm per year. The growth rate is higher in the south of Japan which can reach 0.3mm per year. Normally, the cultured pearls are kept in mollusk for 18 to 24 months to get an ideal nacre thickness. For Tahitian cultured pearls, the average nacre thickness can reach 2mm to 2.5mm after two years for pearl below 10mm in size. Apart from the fact that it influences luster, nacre thickness is the main determining factor for a pearl’s durability.
Normally, size doesn’t have a strong influence on the price of a pearl than the other quality factors. The general rule is that the larger pearl is more expensive than a smaller one under the same condition with all the other quality factors are equal.
So the better luster and the larger size of pearl, the longer period of time will be spend on the pearl culturing process.
