The thing to remember when choosing the pendant's chain length is the circumference of her neck. A 16 inch chain is the most common length and emphasizes the neckline, while an 18 inch chain rests over the collarbones to create a decadent look.

Because a pearl pendant is a showcase of a single pearl, be sure to choose one that is flawless with a very high luster. The setting in the pendant is important as well. For sensational brilliance, choose a pendant set with diamonds graded H-color and SI-clarity. When choosing the gold, keep in mind most women prefer either white or yellow gold; look to her other jewelry to see what she prefers.

Pearl pendants can be elegant or casual depending how you wear them. The wide variety of styles available make it a very versatile, unique gift. For example, a pearl pendant set in a heart-shaped design is perfect for valentine's day. The heart shape is a subtle way to say "I love you" the way no other necklace can.
