No matter where these pieces of jewellery originated from
Indian bangles have been around for hundreds of years, but they are more fun and versatile than ever right now. Jewellery was made from the hills and sands of Saudi Arabia, Afghanistan, and Persia an in particular from the Kurdistan hills. Square disc-shaped etched carnelian beads indicated that there was trade between the West. They originated from Roman, Kurdish, Byzantine and Ottoman times.
No matter where these pieces of jewellery originated from they were and still are a sign of elusive beauty and elegance. Carnelian beads were once considered the property of the noble class. Another origin of beads and bangles is the Middle East.
All gemstones have some characteristics
Many gemstones are used in even the most expensive jewellery depending on the brand name of the designer, fashion trends, market supply, treatments etc. Others are too common and are given a semi-precious status. Most gemstones have good hardness and a high index of refraction.
All gemstones have some characteristics falling short of perfection though; even the seemingly perfect Diamond has four directions of cleavage. Since quartz is everywhere especially in common dirt and dust. Any material that is softer may be scratched during ordinary wear. Nevertheless, diamonds, rubies, sapphires and emeralds still have a reputation that exceeds those of other gemstones.
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.
