SURFACE QUALITY

The surface quality criterion is evaluated according to the combination of three physical parameters: the state of the surface, luster and orient. The quality is assessed by the naked eye.
 The surface condition is evaluated according to various criteria, inclusions, streaks, organic deposits, crimps, grooves, depressions, bumps, protrusions or milky tasks of depigmentation.
The chandelier is the more or less perfect reflection of light on the surface of the Tahitian Pearl. It depends on the regularity of the thickness and arrangement of pearl layers.
A beautiful luster corresponds to a total reflection of light, giving a mirror effect. A Tahitian Pearl without luster will have a matte appearance.
The East, it is the color that comes from the Tahitian Pearl; it is obtained by plogeant the pearl inside a white container that does not reflect light on its surface, the Tahitian Pearl reveals other colors than those visible at first glance; it is often a sign of unprecedented intense emotion, the holder of the Tahitian Pearl discovering at that time one or more new shades.
 The quality of the surface of Tahitian cultured pearls according to the Gemological Institute of America is written well (for the classification of the Tahitian cultured pearl according Tahiti and French regulations, the AAA corresponds to A, AA to B and A to C, no D corresponding to the GIA, evaluation nuances allowing them landing):

These colors are natural, and vary according to the original graft made at the same time as the nucleus but also by farming or lagoon, the Tahitian Pearls sold at POEMOTU all come Tuamotu-Gambier lagoons which are the richest in trace elements and other metal salts to get you in the most beautiful colors.
The Tahitian Pearls with brighter colors are more expensive in their category for one simple reason: to get a Tahitian Pearl of that color, the grafter affix the graft as close to the edge of the pearl and the higher exposure and risky this future Tahitian Pearl makes it all the more rare and exceptional round when spring without some inclusions.
We chose to use POEMOTU classification GIA (Gemmologocal Institute of America) to market our Tahitian pearls because we sell Tahitian pearls worldwide and to be read by the greatest number.
