For reasons such as these, it's extremely important when purchasing pearls to be absolutely certain of the meaning of any descriptive terms used by the seller. If possible, ask for an Authenticity Card. Reputable Jewellers will be happy to comply with such a request. Only in this way will you be able to determine if the price the seller is asking is reasonable.
