The earliest form of jewelry was like an item that an early human found naturally, a bone shell or a bit. Early cemetery also revealed that a prehistoric man buries his dead with ivory beads engraved with flowers. These primitive beads took at least time to make, respectively.
As early as the man has a bit of turquoise occurred in the blue natural region of Turkey, North America. The pearly luster swirl seen in abalone and conch shells would have been used as a jewel.
They may also have found the earliest type of valuable jewelry in the form of natural crystals such as quartz or diamond. Crystals are solid materials in which molecules are symmetrically arranged and they are generally classified in one of six forms:
Isometric or cubic crystals are like blocks and are symmetrically shaped. An example of an equally large crystal is pyrite. It also has a metal yellow or brass color similar to gold, so this is also called fool's gold.
For tetragonal crystals, the crystals are shaped like a pyramid with four prisms. An example of tetragonal is zircon.
Hexagonal crystals are shaped like hexahedrons or pyramids. An example of this type of crystal is Beryl including jewels like Emerald and Aquamarine.
Orthorhombic crystals Examples of orthorhombic crystals are Topaz. Topaz can come in a variety of colors, but is mainly a very rare and amber amber color. At one time, Topaz was much more valuable and devalued the market until a rich vein was found in Brazil.
Monoclinic crystals are short, squat and have inclined faces at each end. Single crystal contains gypsum.
Triclinic's crystal is usually not acute angle and flat. Each crystal has three unequal axes. An example of Triclinic quartz is feldspar.
