Selling and purchasing pearls has been occurring for thousand years, but there is still none mutually acceptable measure. Part of the problem is the fact that there are not two similar pearls and therefore, for a complete grade system hundred of quality parameters would be needed. Some pearls of gemological quality are so rare that they do not allow any comparison. The grade system of quality – Value has five basic factors:
Size. The pearls are measured in mm. Generally, the bigger a pearls is, the more expensive it is. Nowadays, the most popular dimension is between 6,5 – 8,5 mm. The measure of the necklace is always occurred in two sizes, e.g. 7-7,5mm which means that the necklace pearls range from 7 to 7,5 mm. This happens because every pearl is unique.
Shape. The most round and the most symmetrical pearls is the most expensive. Baroque pearls, which are asymmetrical, can be shiny and beautiful but they often cost less that the round ones.
Surface. The perfect pearl must be without any marks, ledges or cracks. The more marks and spots it has, the less it costs.
Color. Pearls are created in different colors ranging from Pink to Black. The color depends on personal taste. However a pink or silver-white pearl suits better fair complexions whereas cream or golden shades suit better dark complexions. We suggest as a perfect color the imperial white, which is with a light pink shade.
Shine. The combination of the surface shine and the depth of the shine of the pearl. High quality pearls must be open, dazzling and able to reflect any object being next to them.
