Buyer's guide
Pearl
GIA judges a pearl on seven things: size, shape, color, luster, surface, nacre quality plus how well the pearls match.
Design with pearlWhat to look for
Larger is usually more valuable. South Sea pearls are the biggest.
Perfect rounds and symmetrical drops are most valued. Fine baroques are loved too.
White and black are classic. Overtones add depth. Unusual colors are rising.
The brighter and sharper the reflection, the finer the pearl.
