Inclusions are one of the most important factors when it comes to gem valuation. In many gemstones, such as diamonds, inclusions affect the clarity of the gem, diminishing the value. In some gems, however, such as star sapphires, the inclusion actually increases the value of the gem. Many colored gemstones are expected to have inclusions, and the inclusions d… WebThese test methods cover four macroscopic and five microscopic test methods (manual and image analysis) for describing the inclusion content of steel and procedures for expressing test results. Inclusions are characterized by size, shape, concentration, and distribution rather than chemical composition. Although compositions are not identified, microscopic …
