Excerpt from Precious Stones and Gems: Their History, Sources and Characteristics In determining the value of gems, it must be borne in mind that a perfect stone is never met with; and that probably not even ten per cent. Of the stones which are brought into commerce are really of fine quality. Much study and attention will be required to attain a thorough knowledge of the properties and appearance of gems but the subject is to most persons of culture one of singular interest, and with the tests mentioned in the Appendix (p.
