All About Diamonds

Diamonds are among nature’s most precious and beautiful creations. Learn more about these enduring gems here.


Established in 1931, the Gemological Institute of America (GIA) is the world’s most trusted authority on diamonds, coloured stones and pearls. GIA created the first, and now globally accepted standard for describing diamonds.

Diamonds can be described based on their:

Carat Clarity Colour Cut

caratHow heavy are your diamonds?

Carat is used as a measure for the weight of a diamond. Five ‘carat’ is about 1 gram. However, the size of a diamond is not the same as the weight of the diamond. The word ‘pointer’ is usually used describe the weight as well. For example, 0.50 carats = 50 pointer.

Since larger diamonds are rare, you are always advised to always compare the cut against the carat when purchasing a diamond.


How perfect are your diamonds?

Like most things found in nature, diamonds are rarely perfect. All diamonds have inclusions or small imperfections inside the diamond or blemishes on the surface. These occur due to the exposure of extreme heat and pressure. Cutting or polishing a diamond, cannot hide these.

The clarity grade categorises diamonds according to number of flaws present. This is because the flaws interfere with the path of light flow through the diamond, thus making it less brilliant. Almost all diamonds are graded for clarity using the 11-point diamond clarity scale created by the GIA.


How can colour be used to assess the quality of the diamond?

 The absence of colour reveals the quality of the diamond. Under the GIA colour grading, a chemically pure and structurally perfect diamond has no hue, like a drop of pure water, and consequently, has a higher value.

The colour grading is determined by using controlled lighting and detailed viewing. The scale starts with colourless — letter D to G to increasing presence of colour — letter H to Z.

Though the differences in the colour are difficult to see, a trained eye can spot them easily.

How shiny are your diamonds?

The word ‘cut’ does not refer to the shape but refers to how well a diamond’s facets interact with light. The facets’ interplay with light, in turn, determines how briliantly the diamond sparkles under light.

Diamond is the most valuable, not only of precious stones, but of all things in this world.
