I am back in the USA, selling items on my farm. Formerly a Gemstone broker in Chanthaburi, Thailand. selling all types of Precious-stones, Carvings & jewelry (2003-2015)
Amazing book for the beginner gemologist and great info
This covers 95% of the stones you will encounter in the gemstone market. Even Australian opals and Tanzanian Tanzanites are covered in the book. Each page is full of info and statistics to help identify if your hunch is correct. From quartz to the precious metals and diamonds.
This is an all around top choice for gem books i have ever used and i still use it daily.
