Know Your Diamond

To ensure that we take care of our customers and their interests long after the purchase has been made, we have listed down some useful facts about diamond and gold jewellery. A diamond’s worth is judged by taking four factors into consideration: Clarity, Colour, Carat and Cut, collectively known as the 4Cs of a diamond.


  • Diamonds are mostly pure carbon. However, during crystallisation, other crystals may get trapped. These are known as ‘inclusions’.
  • Diamonds are assigned grades between F (Flawless) and I(included). Diamonds with high clarity grades are rare and more valuable.


  • Colour is the net combination of Hue, Tone and Saturation.
  • The colour of a diamond greatly affects its value. The rule of thumb is that colourless diamonds are more valuable than coloured diamonds.
  • Diamonds are rated from D to Z, D being colourless and Z being the most coloured.


  • The cut of a diamond is the human contribution to enhance its beauty and value.
  • It is what gives a diamond its brilliance, which is a combination of lustre, dispersion and scintillation.
  • Few popular cuts are Round, Marquise, Emerald, Princess, Pear, Oval, Heart, Baguette and Trillion.


  • ‘Carat’ is the unit of weight used for all gemstones, including diamonds.
  • One carat is subdivided into 100 ‘points’ and 5 carats equal 1 gram.
  • Larger diamonds, being more rare and desirable, are more expensive than smaller ones.
  • Prices of diamond increase with size.
