THE PRECIOUS STONE AGE

THE PRECIOUS STONE AGE


Coming from a country where some of the finest Gemstones (precious stones) are found ,I have decided to do some studying about them. After all they are  “…a girls best friend” right! 😀

So below is a list of famous precious stones!

1. Diamonds

  • Allotrope of carbon.
  • It has the same formula of a graphite in a different shape (Shape matters! LOL!)
  • For you non chemical people its like the prettier sibling of graphite! 😀

2) Blue Sapphire

  • My country ,Sri Lanka, is famous for it 😀
  • It is a makeup of corundum or Aluminium oxide.
  • Its blue and beautiful: vivid medium dark violet to purplish blue is described as the fine blue sapphires and are most expensive.
  •  Sapphire is derived from the Greek word “sappheiros” which means “precious stone”.

3) Ruby

  • Ruby is the name given to red sapphires. Therefore is also made of corundum/ aluminium oxide.
  • Found in places where blue sapphire is found ( Sri Lanka!)
  • No other gemstone apart from diamond is harder than Ruby.
  • In ancient sanskrit, ruby is called Ratnaraj which means king of gemstones.

4) Star Sapphires

  • So basically flash a light onto this stone from above, you can see a star-like phenomenon known as asterism.
  • Some of its finest collection is found again in Sri Lanka.
  • Found in many shades of  blue,purple and red.
  • The stone exhibits 6 rays usually.

  • My personal favorite solely based on its scarcity.
  • Its green (made of chromium and sometimes vanadium).
  • Their toughness is generally poor.
