Learn About Pearls

Pearls have been valued for more than four thousand years. This guide will help you to understand the various aspects of a pearl. Pearls are obtained from pearl oysters and in every 10,000 oysters one might find a single Pearl. Due to its rarity and high value cultured pearls are mostly available in the jewelry market. Amidon Jewelers offers you a wide array of pearls like Freshwater, Akoya, South Sea and Tahitian. The qualities of pearls are defined below.


The body color defines the general color of the pearls. Some of the common pearl colors are white, cream, silver, pink, yellow and black. Some overtone can also be found when light is reflected off the pearl surface. Apparently a pearl might appear white, but when closely observed it shows a pink overtone.


The shine produced by the pearl is called luster. The substance nacre is created when light is reflected off the surface of tiny layers of calcium carbonate crystals that creates a pearl. If the pearl is larger then it would have more nacre and hence more luster. A 5 mm pearl will definitely have less luster than a 10 mm. Hence bigger the size of the pearl more luster it will have.


Round shape in pearls is considered to be of high quality and rare as well. Asymmetrical and non-spherical shapes are considered lower quality. Amidon Jewelers offers you the highest quality of pearls. Pearls from Akoya, Tahiti and South Sea have round shapes, whereas Freshwater pearls can be oval in shape. For reference see the chart.

Surface Quality

In the layering process of a pearl, sometimes spots and bubbles appear as the nacre doesn’t remain smooth. A pearl with smooth surface is of very high value. Amidon Jewelers offers you various surface qualities of pearls to suit every pocket.


Pearl sizes depend on its type. Freshwater pearls size ranges from 3.0-7.0 mm, Akoya pears ranges from 6.0–8.5mm, South Sea and Tahitian pearls sizes can be large as 13mm.
