Factors that decide Tahitian Pearls Grade:
Which parameters decide the grades of Tahitian pearls, understanding this is very important. 7 different factors decide the price and grade of a Tahitian pearl. Here it goes:
Luster: Luster is the surface of the pearl that reflects the light falling on it. The shiny surface reflects light beautifully creating a highly desirable effect. And these pearls are considered of high quality. While low-quality pearls have a dull surface, which reflects light poorly they are less valuable and attractive. High-quality pearls have excellent luster and command high prices. While pearls with poor luster can be bought at much lower prices.
Color: Color determines the value of pearls and is among one of the most important factors. Rich and deep-colored pearls, with even and consistent compositions, are valued more. From white to black everything in between can be the color of Tahitian pearls. High-quality pearls usually have strong and saturated colors.
Shape: Tahitian pearls are noticed in a wide range of shapes from perfectly round to baroque. The most valuable Tahitian pearls are round ones.
Size: Larger pearls are rare and look more impressive due to their greater luster. These pearls take a longer time to grow and are more desirable. Tahitian pearls typically range in size from 1 MM to 20 MM.Nacre Thickness: Nacre is an extraordinary strength material deposited on the inner shell of a mollusk that creates a pearl. Its thickness and uniformity affect the luster of a pearl. Highly valued pearls have uniform layers of nacre and smooth surfaces.
Surface Quality: Inclusions, which blemish the surface are not easily noticed in Tahitian pearls. Deep inspection can be helpful. The clearer surface of a pearl makes it more valuable.
Pearl Matching: How well pearls match each other, is an important factor to consider. Shape, size, color, and luster are the terms in which the pearls should be matched, as they are used together in strands. So, two different pearls may be individually highly graded due to their excellent qualities. But they are poorly graded as they don't match.
