1: Excellent book on gemstone
This is an excellent book for anyone wanting to learn about the physical properties of gemstones. It would be especially useful to students interested in the scientific properties of gems. I found it useful because it describes where gemstones are found and how and when they were discovered. I would highly recommend this book to anyone interested in the subject.

2: The Old Ones are sometimes still the Best
This books been around for quite a number of years now but has to be simply the BEST illustrated book on Gems there is. It's absolutely jam packed FULL of all the information you need to learn about precious stones.
|
3: Underwhelmed
Well written but a bit out of date. Scientific data often ages like egg salad on a warm day.
|
4: Simon & Schuster's Guide to Gems and Precious Stones
an encyclopedia of knowledge on stones and gems.
|
5: its my 10th gem book
and it is a little more technical than the rest (explains things like twinning, establishment of density, calculating specific gravity, cleavage, moh's scale, refractive indices, law of refraction, genesis, cutting, cutting styles etc).
it includes gem descriptions in much detail (thou the order in which they are arranged is a mystery to me and really bugs me, as i have to flip and flip until i find what i need).
for diamond it includes a table comparing 4 color grading systems used (which is cool).
large section on organic gems and synthetics.
all in all i see it as a really good (almost) professional level book on gems and precious stones.
