With several institutes offering specialized courses in this field, jewelry designing is no longer a family trade but a lucrative career option for first-generation gemologists who can cater to a niche market for custom-made and designer jewelry. And other professionals are like gem appraisers. Jewelry designing has come out of the closet; it is no longer a cloistered trade carried out by semi-literate goldsmiths in family vaults.

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.

Elements, by the chemical definition are composed of all the same atoms; whereas substances composed of two or more elements are compounds. These minerals, which combine metals such as iron with the very non-metallic elements of carbon, nitrogen, phosphorous and silicon, are quite unique and quite rare. But the sulfides class is by convention limited to sulfur and semi-metal combinations as discussed above. They are not too different from sulfides which typically combine metals with sulfur.
