What determines the value of a pearl?

They're seven factors-size, shape, color, luster, surface quality, nacre quality and matching.

Color strongly influences the value of Tahitian pearls.

Akoya cultured pearls size is a major factor. The most common size is 6 or 7mm.

There are seven pearl shapes-spherical, round, near-round, symmetrical, oval, button, drop and baroque. This pearl bracelet is so easy to wear.

Colored pearls come in many colors. Apricot, Aubergine, Golden, Lavender, Peacock and  Pistachio.

Luster is probably the most important factor.
