  • A gemstone or gem, also called a precious or semi-precious stone, is a piece of attractive mineral, which when cut and polished is used to make jewelry or other adornments.
  • However certain rocks, and organic materials are not minerals, but are still used for jewelry, and are therefore often considered to be gemstones as well.
  • Most gemstones are hard, but some soft minerals are used in jewelry because of their lustre or other physical properties that have aesthetic value.
  • Gemstones are identified by gemologists, who describe gems and their characteristics using technical terminology specific to the field of gemology. The first characteristic a gemologist uses to identify a gemstone is its chemical composition.
  • There are a number of good machines available for cutting precious stones - a process called faceting.
  •  Although the machines may look
    complicated, they consist primarily of a grinding plate called a lap and a set of protractors that help the faceter hold the stone accurately against the
  • The faceter controls the actual faceting process during the grinding and polishing processes on each face of the stone.
  • Raman micro-spectroscopy is an ideal method for the examination of marketable gemstones. The lack of sample preparation and the
    non-destructive nature of Raman analysis make it ideal for the analysis of even high-value gems.
  • Gemstone is heated to high degrees which is called gemstone heating. Most real Blue Sapphires today are heated to high degrees during natural faceting process.
  • Merchants in Peshawar, Pakistan, cut low-value stones for the domestic market and send the medium and high quality stones to centres around the world for accurate cutting for the Western markets.
  •  The gemstone and jewellery sub-sector in Kenya is liberalized; there are no trade restrictions. So long as a miner or dealer is licensed, he or she can trade in an otherwise free market.
  • The gems and jewellery industry occupies an important position in the Indian economy. It is a leading foreign exchange earner, as well as one of the fastest growing industries in the country.
