Amber is the fossil resin from a pine tree that flourished in the Baltic region (and other localities) some 25 to 60 million years ago. Globs of this aromatic sap poured down from prehistoric trees, often trapping insects, twigs, bark and leaves. Amber is one of the few gemstones of organic origin.  In ancient India and Egypt, amber was burned as an incense, believed to purify the surrounding area. Amber is abundant along the shores of the Baltic Sea where it is mined extensively from Tertiary glauconite sands that are from 40 million to 60 million years old ... [[Amber|more]]

In "Secrets of the Gem Trade (The Connoisseur's Guide to Precious Gemstones)" Richard Wise leads you through the swamps of the gem trade.
 
With an almost novelistic penmanship he teaches you how to judge and grade quality in gemstones while clearing some dogmas along the way.
 
Whether you like to know what the best color is in Tanzanite, or how to grade a Diamond, you will find it in this book. No other book I read before dealt with this topic in such detail as Richard Wise's masterpiece.
 
  
He will not bore you with large tables of refractive indices, nor will he try to make a gemologist out of you.
 
What he will do is make you an expert on colorgrading and judging quality through good old, and fun, reading.
 
Not holding back he reveals the secrets of gemdealing and how to act as a pro in the field.
 
This book opened my eyes and titillated my senses to a degree that I wanted to catch the next plane to Bangkok and try it myself.
 
  
This extensive work is a must for every professional in the gemstone industry. It should be made mandantory reading for all jewelry appraisal courses and every selfrespecting gemologist should have this book on his desk, not on his shelf.

Color filters have many uses in gemology. The Chelsea Colour Filter™ (CF) is the most prominent of them.
 
While the CF is the most used, other filters can serve for a variety of applications. Among those are diffused colored plates used in conjunction with a microscope to inspect sapphires, narrow bandwidth filters to determine dispersion, and blue, red or yellow filters to examine fluorescence in gemstones.
 
  
Some people regard the CF as a primary tool, yet all modern gemology writers disagree with that statement. It can, however, give clues to the identity of a gemstone when used as an additional (secondary) tool. One can never rely on observations with any color filter alone ... [[Color Filters|more]]

Welcome to The Gemology Project

The Gemology Project is a non-profit gemstone and gem science wiki-style database for anyone interested in gemstones and gemology (gemmology). Every month we highlight a gemstone and a piece of gemstone identification equipment to help us all understand more about the wonderful world of colored stones and diamonds. The Project begins with a general tutorial as an Introduction to Gemology.

We invite every gemologist, gemstone dealer or gem enthusiast to share their practical and theoretical gemological knowledge and help this central gemology repository grow.
