Overview

Geological Studies of Colored Stone Gem Deposits


Details

Colored stone deposits occur in a wide range of environments, and these determine the types of gem materials that form and their properties. With new analytical methods providing valuable data on color-causing elements and diagnostic inclusions, country-of-origin determinations should become more accurate. These findings will also provide clues that can be used to find similar types of gem deposits.
