The  Chemistry , Properties  and  Tests  of 

Precious  Stones 

by  JaWv^  Martin/ 

This  is  a good  basic  introduction  to  gemstones  and  their  analysis.  Admittedly  a lot 
of  the  scientific  tests  have  been  superseded,  but  the  basic  properties  never 
change.  The  first  part  of  the  book  concentrates  on  physical  properties  of  most 
common  gems,  then  outlines  the  cutting  process  and  ends  with  several  chapters 
on  each  of  the  gemstone  families.  A useful  little  book  if  you  are  interested  in 
gems.
