Pearl Guide

Surface Perfection

Subtle blemishes and marks are part of a pearl’s natural texture and proof of its authenticity. These blemishes are the result of sea particles that drift into the oysters and brush against the pearl as it forms. Fewer surface imperfections denote a higher quality, more valuable pearl.

Shape

The pearl experts generally categorised pearl shapes into 3 broad categories, based on their overall characteristics.


The three main categories of Pearl shapes


Spherical
Spherical shapes are perfectly round or nearly round. They are the “classic” pearl shapes that is most familiar.

Symmetrical
Symmetrical shapes are balanced and regular. If you sliced this pearl in half, each half would be a mirror image of the other half.

Baroque
Baroque shapes are irregular or abstract. They are non-symmetrical in nature.


The Seven Basic Pearl Shapes


Within these three broad categories, pearls can be classified into seven basic shapes

Round
Round pearls are perfectly spherical the shape most people think of when they think of a pearl. Because of their relative rarity and “classic” nature, they are highly desirable.

Near-Round
Near-round pearls are not perfectly round. Instead, they are slightly flattened or elongated, rather than being a perfect sphere.

Button:
Button pearls are flattened to some degree, making them resemble a button or perhaps a disk rather than a perfect sphere. These pearls are often used in earrings, where the flattened side can be attached to the setting.

Drop:
Drop pearls are pear or teardrop-shaped. The drop can either be “long” or “short”, depending on its proportions. These pearls make attractive earrings or pendants.

Semi-baroque:
Semi-baroque pearls are slightly irregular in their shape. For example, a pearl which might otherwise be considered an oval, button or drop pearl, but which is not symmetrical in natural, would be considered semi- baroque.

Baroque:
This is a pearl that is both non-symmetrical and irregular in shape. The baroque pearl can be purely abstract in its shape, or it can resemble a cross, stick, or some other shape.
