Roll a strand of pearls along a flat surface to determine if all pearls are strung through their exact centers. All pearls should roll evenly, without an eccentric wobble. Buy the best pearls you can afford, then choose the clasp. A decorative jeweled clasp can always be purchased later. Select a cultured pearl necklace, too, for its effect on your appearance and personality.
Long necklaces are slinky and sexy.
Short necklaces can be demure or sophisticated. Dog collars enhance a long neck. Longer strands slenderize and appear to elongate the neck. For fair skinned women, roseate hued pearls are most flattering. Cream and gold color pearls set off darker skin tones best.
