Gemstones are identified by gemologists
Gemstones are identified by gemologists. The first characteristic a gemologist uses to identify a gemstone is its chemical composition. Gems are characterized in terms of refractive index, dispersion, specific gravity, hardness, cleavage, fracture, and luster. They may exhibit pleochroism or double refraction. Who describe gems and their characteristics using technical terminology specific to the field of gemology.Next, many gems are crystals which are classified by their crystal system such as cubic or trigonal or monoclinic. They may have luminescence and a distinctive absorption spectrum. For example, diamonds are made of carbon (C) and rubies of aluminium oxide (Al2O3). Another term used is habit, the form the gem is usually found in. For example diamonds, which have a cubic crystal system, are often found as octahedrons.
Cleaning is must in gemstone
For stubborn dirt, a soft brush can also be used on these types of stones. In hot environments, the heat can cause the water to evaporate and discolor an opal. Jewellers use mechanical cleaning procedures to clean gemstones. Some of these methods can be harmful if done incorrectly, so ensure that the cleaning is being performed by a qualified professional.One common method is ultrasonic cleaning, which uses frequency waves to clean gemstones. They can be cleaned in the same mild detergent and water solution as other gemstones, and delicately scrubbed with a very soft brush. Designer jewellery can cover the gamut of rings, engagement and wedding rings, watches, necklaces and pendants, bracelets and anklets, cuff links, tiaras and other unusual pieces.
