The Chemistry, Properties and Tests of Precious Stones - John Mastin - Bog

The Chemistry, Properties and Tests of Precious Stones is a classic geology text by John Mastin. Some little time ago certain London diamond merchants and wholesale dealers in precious stones made the suggestion to me to write a precious gem study on this section of mineralogy, as there did not appear to be any giving exactly the information most needed. Finding there was a call for such a mineral guide I have written the present volume in order to meet this want, and I trust that this handbook will prove useful, not only to the expert and to those requiring certain technical information, but also to the general public, whose interest in this entrancing subject may be simply that of pleasure in the purchase, possession, or collection of precious stones, or even in the mere examination of them through the plate-glass of a jeweller's window.
