Demand for a new breed of jewelry designers
Growing market for branded jewellery has led to a demand for a new breed of jewelry designers. Instead, thanks to the advances in technology, it has landed on the drawing board with some firms even using computer-aided designs to create exquisite pieces in virtual reality.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. Also passed down like a well-kept secret from generation to generation.
The color is the greatest difference in the metals
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.
A diamond is a form of carbon
A diamond is a form of carbon that was created deep within the core of the earth more than 3 billion years ago and brought to the surface by volcanic eruption. In diamond, each carbon atom is bonded to four other carbon atoms in a tetrahedral structure, like a pyramid.Each link or bond is the same length, and the tetrahedral formation is therefore completely regular. Theoretically a perfect diamond crystal could be composed of one giant molecule of carbon. After the magma cooled, it solidified into kimberlite, where the precious rough diamond is still found today. It is the strength and regularity of this bonding which makes diamond very hard, non-volatile and resistant to chemical attack.
