In some countries all gemstones are sold with a laboratory certificate. A certificate or identification report confirms the gemstone variety and natural origin of the stones. In some countries, a certificate may also include information about where the gemstone was mined, based on a study of its inclusions. Although certificates from a major laboratory provide support for your purchase, in many countries, including the United States, there is no official regulation of who can offer a certificate. Some certificates are reliable and some are just fancy letterhead with the signature of some unknown person. Even certificates from reputable labs can be forged. Certificates are a common feature to gemstone investment scams, especially common in sales pitches over the telephone or on the Internet. You should be careful about accepting certificates as some kind of guarantee. Never buy a gemstone in a sealed package and never buy a gemstone by a certificate alone, over the telephone as an investment. Sapphires do store wealth and are an excellent way to pass down something fine and valuable to the next generation but they are not a liquid investment.
