Pearls come in an infinite combination of shape, colour and size and no two are exactly alike.

When buying pearls look for the deep inner glow and shimmering iridescence, known as orient. The deeper the lustre and iridescence, the more precious the pearl.

Colour tones should be clear, not dull or muddy.

Flawlessness in a pearl is very rare, with the majority bearing small natural blemishes. They are marks of individuality and testify to the pearls authenticity, but watch for cracks, chips or disfiguring blemishes.

Size influences the price of a pearl. As larger pearls are rare, they seldom grow to more than 15mm, they can cost more. However a smaller pearl can attract a higher price if it is superior in orient. South Sea Pearls are the largest in the world.

The more symmetrical the shape, the more valuable the pearl. Exact symmetrical shapes include round, pear shape, tear shape, and oval. Pearls of asymmetrical shape are termed baroque.

All pearls in a strand should match well in regard to lustre, orient and colour. Roll a strand of pearls along on a flat surface to determine if all the pearls are strung through their exact centres.
