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.

Alloys that are composed of semi metals with metals are classified as sulfides but are sometimes listed as elements. For thousands of years, gold has been valued as a global currency, a commodity, an investment and simply an object of beauty.We personally select and purchase rough and cut stones. They usually share similarities to other sulfides in their physical properties. These minerals are in the Selenides, the Tellurides, the Antimonides and the Arsenides Subclasses of the Sulfide Class. The main difference between elemental alloys and these semi-metal alloys is the presence of covalent bonding in these minerals as opposed to the strictly metallic bonding in pure metals and their metal alloys. Our specialty is top quality cutting.
