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. 309), a little study will generally
enable the observer to distinguish the true from the false.
With
objects such as those referred to above, I am publishing the present
volume, which is the sixth edition of the original work ; and I hope
that in the revised form, which it now presents, it may be of service
to those who have occasion to handle Precious Stones as a matter of
business, as well as to the wearers of these beautiful objects.
It
must be borne in mind that this book is not intended to be a strictly
scientific treatise, but rather a practical work for those who, whether
in the trade or among the Public at large, desire to obtain some
knowledge of the general characteristics of Diamonds and other Precious
Stones and Gems.
In
conclusion, I trust that the Goldsmiths' Company, as fathers of the
trade, will ere long throw open their fine suite of rooms in Foster
Lane, and will not only establish a comprehensive library of books
bearing on the study of jewellery, but by giving gratuitous Lectures on
Precious Stones and Precious Metals, will offer that aid to the younger
members of our trade, which is necessary for a proper understanding of
their daily business. This ComÂpany have already done something, but we
must look to
