What is Gemology?

Posted by Daniel Lawrence on August, 2016

Gemology is the study of gemstones. Certified professionals in this field are called gemologists. A gemology expert in Union City CA area or other areas around the U.S. can help you identify, grade and appraise gemstones.

A true expert can tell what a gemstone is from just looking at it, although in some cases this may not be possible. For example, a blue topaz and aquamarine can look identical and difficult to determine which gem is which. In this case, the gemologist will have to perform a series of tests to correctly identify the gem. Oftentimes, more than one test is needed to accurately identify the gemstones.

Once they’ve been identified, the gems will also need to be graded. This helps to determine the value of the stone. A grading report takes into consideration the quality of a gem’s color, cutting properties and clarity. Obviously, the higher the grade, the more the gemstone is worth. There are various grading systems, and grades can vary depending on the gemologist performing the tests.

Gemologists are also responsible for appraising various gemstones. This typically involves assessing the cut and polished stone. The appraisal will determine whether the stone is natural or synthetic, and how much it is worth. While some appraisers work independently, others work in jewelry stores and auction houses.

With tough economic times, more people are looking to gemologists to appraise their gold and jewelry. Once it’s been appraised and you know how much you could sell your gemstone for, you can make an informed decision on whether to sell or not.

Appraisals of gemstones are not only valuable if you want to sell them; they are also necessary if you want to insure them against theft, fire or other disaster. Insurance companies need to know the value of your stone so they can include it in your policy and set your insurance premium.
