The color is the greatest difference in the metals. The elements which include over one hundred known minerals are a diverse class when taken as a whole. The non metals are extremely diverse. Due to the diversity of the non metals subclass there is most of this diversity.
The non-metals include some elements known as semi-metals who share some properties with metals but differ in other characteristics. The hardest mineral known to man is from this subclass, as well as one of the softest. The Metals Subclass and related metal alloys contains metals whose properties are rather similar due to the common way in which they crystallize and bond.
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.
