GEMSTONE & MINERAL DATA BOOK by John Sinkankas has all the
you would wish on this , and other gemological subjects.
The one drawback to this book ( 350 pages ), is that there is SO
much and the organization could have been better. I
highly recommend it Available in trade soft back and hard back. It
is out of print and still in demand.
I had 2 soft back copies, gave 1 copy to my school and bought a
hardback copy. I have 1 soft back copy to sell. The books are the
same except the paper and binding quality. I have several other
duplicate copies of other gemology, or appraisal books ( in good
shape ) which are surplus . I would like to sell these so as to buy
TIP - The newest copy of HANDBOOK OF GEM IDENTIFICATION BY Richard
T. Liddicoat comes in soft back only. After a month the pages fall
out of the glued in binding. So Get a printer to cut down the pages
and punch holes to fit a 6 X 8 , 3 ring binder. I got a 3 in wide
back Avery binder. The pages fit very well, and I can insert
additional pages with comments and up dates into it. This saves
time, and supports the identifications.
Time became important at TIJT Paris Tx.'s Gemology School. We were
required to properly identify some 450 gemstone specimens in the lab
portion, for graduation. This was the hardest part of the 40 hr /wk.
1 semester class.
The British F.G.A has opened up a Gemology School now at TIJT. They
wanted to open a school in the USA and the existing school ( G.G.S.)
shared many similarities with FGA.
