SAPPHIRES, ARE THE MOST VALUED GEMSTONES IN HISTORY

  • Sapphires are the most highly valued and hardest gemstones behind diamonds. The color par excellence of the sapphire is blue, however, we can find it in green, yellow, violet, black or transparent.
  • With a hardness of 9.0 on the Mohs scale, sapphire is the third hardest mineral on the planet, after diamond and moisanite which have a hardness of 10 and 9.5 respectively.
  • Both sapphire and ruby belong to the corundum family, a type of crystalline mineral rock made up of aluminum, iron, chrome and titanium. Although the colors of each of these gems will depend on the impurities they contain, that is why the variety of red corundum is called ruby, while all other colors are known as sapphire.
  • Sapphire is the official birthstone of the month of September. It is also one of the stones representing the zodiacal signs of Pisces, Taurus, Virgo and Sagittarius.
  • Sapphires with rutile needle inclusions have a property called optical asterism. This is the effect seen in the form of a star in star sapphires and we usually find them only in cabochon cuts.
  • They are usually used in meditation. They say that their luminosity gives clarity to the interior of people. It brings peace of mind and helps to have better intuition and awareness. Sapphires are also known to be the ‘Prosperity Stones’ because they are a gift that releases bad thoughts and help in depressive states.
  • Sapphires are also used to make objects and protect them because of their hardness. The first company that used these jewels in their devices was Apple to protect mobile phone camera lenses or the home buttons of Iphones.
