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.
Diamond's clarity is graded
Diamonds with Slightly Included and better grading are progressively more expensive. These include; internal graining, cleavage, bearding, cavities, crystals or minerals, knots, feathers and clouds. After that, we go to the various grades of included diamonds. There are two types of flaws: an inclusion and a blemish. A blemish is something that mars the surface and distracts from diamond clarity.
This includes chips, pits, nicks, scratches, naturals, grain boundaries, and polish lines. The Internally Flawless diamond cannot have any inclusion, but may have surface blemishes. The diamond is then graded on the basis of five considerations: color, nature, position, size, and number. The clarity of the diamond is one of the primary determinants of price when it comes to rings, earrings, and other jewelry. This article will focus on how a diamond's clarity is graded.
