Gemstone identification is done by a gemologist. They distinguish gems and crystals in a non-destructive way. This means that a limited approach of evaluation is available. Only optical and physical measurements, without the need of the chemical analysis and scratching methods are used because chemicals can destruct the value and natural brilliance of the stone. Frequently sole visuals, precisely carried out characterization of gems is enough to have a high enough certainty.

The price of the gemstones and crystals is largely based on the solidity, natural beauty, and uniqueness. For many centuries, these unique qualities are well established parameters that people today continue to use. The coloration of each gem is as well determining feature used to asses the richness and pureness of the object. Yet another gem property is the unique gravity, typically measured by heavy liquids. Although color is a property, it is not a dependable testing manner because it can be misguiding. Even so, color recognition can help the gemologist limit possible options. Commonly used tool for this technique is the binocular microscope, along with a hot needle for turquoise and amber testing, solvents for removing of dyes and coatings, simple magnet, and dilute acids.

Fashion in our time keep on to evolve, keep going forward and stay up-to-date, but the attraction for these commodities will never wade, and will even become stronger. The way they are produced will see changes, but their use to the consumers not. In addition, the market may continue to experience ups and downs, and will cause the value of gems and crystals to decrease and increase over time. Still their stocking value will stay in the future.
