Pearl classification continued

An axis of symmetry means that you can drill it from one end through to the other, spin the pearl along that axis and not see it wobble. Pearls that wobble are known as baroques. Baroques have personality and are a personal favorite. Semi-baroque is a large category that encompasses drops, buttons, ovals and all of their variations. It is said that a perfect drop is every bit as valuable as a perfect round, no doubt due to its rarity. The last category is the circles. Circular rings in the form of the pearl that do not descend lower than 1/3 of the pearl define circled pearls. It's unknown why but circled pearls are by far the most colorful.
