It looks like every girl has, or wants, a gorgeous set of pearls. They are elegant, go with just about everything, and make the girl wearing them feel special. A lot of women got pearls for the graduation, or their sixteenth birthday, or in commemoration of another special occasion, and although fairly, they most likely weren't top-shelf quality.
If you are ready to surprise that special woman in your life with the best pearl necklace she has ever owned, here are a few pointers that may help you decide on the best.
Unlike any other stone, grading pearls isn't. The specific attributes are somewhat different, but what makes them valuable stays the same. Pearls are rated for luster, color, size, shape, size, and number of imperfections, and, in the event of a multi-pearl jewelry, how well-matched the pair is.
Pearls all start out exactly the same manner – like a grain of sand stuck in a mollusk. The sand, an irritant, gets coated with a coating of an organic substance called nacre, a becomes the beginning of a pearl.
As pearls are chosen, graders value every pearl based first on its luster. This is the quality of a pearl. A pearl with higher luster will reveal light reflecting from the various layers of nacre inside the pearl's structure. The more layers, the more reflected light, and the diffraction of the light in the pearl set its base value. Pearls with higher luster look as if you can reach down deep within them and touch the center.
