The gemstone would shine as white light that emits from the surface and inside of a diamond and is called as brilliance. The light that enters a diamond is split into rainbow colors on to the other surface. This dispersed light is known as the “fire” of the diamond.
  4. Light will bounce in opposite direction when reflected on diamond and it will pass through other gemstone.
  5. Original diamond can scratch your mirror with its edge but duplicate one cannot, as diamond is very hard gem and it is specially used to cut the mirror.
  6. Observe your diamonds edges with the help of a loupe. A real one would have sharp edges whereas fake stone will have rounded edges.
  7. Diamonds can be tested by fog test. When air is blown from the mouth on the top surface of the diamond there will be zero appearance of fog and that in other stone it will appear for few seconds.

Diamond’s shine and glitter depends on four “C” i.e. Carat, Clarity, Color and Cut. These four “C”s are graded with GIA scales as shown below:

Carat: Diamond is weighted by metric carat. Five carat is equal to one gram and one carat is divided into 100 numbers. 50 number of diamond means it is equal to 0.50 carat.

Clarity: Blemishes on the surface of the diamond, limit the amount of light to enter in the diamond. So clarity of the diamond will affect its actual property to shine. Clarity refers to the inclusions, or tiny birthmarks on a diamond. The fewer inclusions, the more expensive, pure, and rare the diamond is.
Clarity Scale

Color: Most of diamonds are little yellowish and brown in shade. But the white diamond is very rare and costly. GIA gives the exact color of the diamond in alphabetical order from d to z. Diamond of category D is known to be the purest one.

Cut: The cut that enhance the brilliance of a diamond to get the best gleam as if the shape is too deep or shallow it will not give its actual shine.
