Diamond Varieties Based on Four Cs

Four Cs are one of the popularly used methods to categorise diamonds based on the diamond grades.

Colour

The colour of the diamond is the first thing anybody will notice. People may prefer the colour based on their budget and personal taste. Colourless diamonds are of great value even though they may have a brown or yellow hue which is not visible to the naked eye. The yellow tinge in diamonds is due to the presence of nitrogen. GIA (Gemological Institute of America) grades diamonds from D to Z, out of which D is of premium colour (usually colourless), and Z is of poor colour quality (with heavy tint). The best diamond jewellers in Chennai procure more D-colour diamond ornaments to stand out from their competitors. Usually, the diamonds with tints that can be seen with the naked eye are categorised as K colour. The tints are noticeable beyond the S colour at all angles.

Clarity

When you contact the famous diamond jewellers in Chennai, you will see them describing the stone's quality with VVS. Clarity is a measure of the flaws in a diamond. According to the clarity, diamonds are classified into:

  1. FL- Flawless diamonds with no blemishes or inclusions are termed FL diamonds. Skilled graders use 10x magnification to check their clarity.
  2. IF- Internally flawless diamonds that contain blemishes and no inclusions fall under the IF category, and these blemishes can be seen when viewed under a 10x magnifying glass.
  3. VVS1 & VVS2- These diamonds have slightly included inclusions when viewed with a 10X magnifying glass. This is the most commonly used clarity by the best diamond jewellers in Chennai.
  4. VS1 & VS2- Minor inclusions are visible in these stones when viewed under a 10x magnifying glass.
  5. SI1 & SI2- When viewed under 10x magnification, noticeable inclusions are seen in these diamonds.
  6. I1, I2 & I3- These diamonds have obvious inclusions under 10x magnifying glass with reduced brilliance and transparency.

Carat

Carat is the measurement of the size and weight of a diamond stone. The larger the diamond, the higher its value. Famous diamond jewellers in Chennai have numerous affordable diamonds of great quality. A high-carat diamond is of greater value than one with a low carat. A pure and colourless diamond of one carat is better than a large diamond stone with lesser clarity. Therefore, carat is an important factor to consider while buying diamonds as it indicates diamond quality.

Cut

Cut refers to a diamond stone's finish, proportion, polish and symmetry. It is a visible feature which is enhanced through cutting techniques. A diamond's cut affects the sparkle, brilliance, scintillation, and brightness. The cut-based classification includes:

  • EX- Excellent
  • VG- Very Good
  • G- Good
  • F- Fair
  • P- Poor

The best diamond jewellers in Chennai have various well-polished, symmetrical diamonds with VG or EX cut quality.
