| − | ==Gem Identification==
| |
| − | Methods used to identify gems from similar looking species, separate them from imitations and to recognize enhancements and treatments. Since most gemstones are minerals that have a uniform chemical composition, giving them a consistent set of physical and optical properties, accurate measurement of these properties greatly helps gem identification.

| |
| − | ===Issues===
| |
| − | Largest issues of gem identification are failing to consider all possibilities and misinterpreting test results.
| |
| − |
| |
| − | ==Imitations==
| |
| − | High value of gems have led to various forms of imitations over the years.
| |
| − |
| |
| − | ==Treatments==
| |
| − | Treatments developed to raise apparent value of stones.
