mineral book:"Van Nostrand's standard Catalog of Gems", John Sinkankas, 1968

Description

Here is an older classic. All books written by John Sinkankas contain relevant and well sourced information on gemstones and minerals. Take away some for the more period stuff, like pricing.. and you still will retain a lot of factoids about gemstones which are useful today.
As seen, this book is in very good condition. Please be advised, I ship with Priority shipping, padded envelope.
