Pearl grades
Most saltwater and freshwater pearls are graded on a four-point scale (AAA; AA; A or B). AAA pearls are closest to spherical and have the highest luster; in strings, they are most closely matched in size. B pearls have little luster and vary greatly in shape, color, etc., and may have obvious blemishes. A special system is used by Tahitian pearl traders, Tahitian pearls are ranked from A thru D using criteria similar to the salt and freshwater systems. So, if someone tries to sell you an A or B-grade pearl, be sure you know who gave out that grade!
Old wives' tale?
You really can tell if pearls are real by rubbing them against your teeth! Because pearls are natural creations, they are not perfectly round. The surface imperfections of real pearls feel a little rough or gritty against the teeth. Imitation pearls will feel smoother, almost slippery--sorta' like the guy who's trying to palm them off as the real deal!
Regardless of when or why you choose pearl jewelry, get what you pay for by knowing what to look for.
