Some diamonds can glow when they're under special light called ultraviolet light. This is called diamond fluorescence. It happens naturally and doesn't always affect how valuable the diamond is. Some people like diamonds that glow, and some people don't mind if they don't glow. It all depends on personal choice

Diamond cut refers to how a diamond's facets are proportioned and arranged. It is important because:

  • - A well-cut diamond reflects light better, making it more brilliant and sparkly
  • - The cut affects the diamond's interaction with light, giving it that beautiful shine we love.

You can determine if a diamond is genuine by following these steps:

  • - By looking at the certificate. If the certificate shows 'NATURAL DIAMOND', it means your diamond is genuine
  • - By matching the Girdle 'Inscription number' with the certificate 'report number'.

A diamond certificate is an official document issued by a gemological laboratory that provides detailed information about a diamond's 4Cs and other characteristics. A diamond certificate is important because:

  • - It assures you of the diamond's authenticity and quality
  • - It helps you make an informed decision when purchasing a diamond
  • - It proves the diamond's value and can be useful for insurance


The 4Cs of a diamond are the four main factors used to evaluate its quality and value:

  1. Cut: This C refers to how well the diamond has been shaped and faceted from its rough form.
  2. Color: Diamonds come in various shades, from colourless to light yellow or brown. The less colour a diamond has, the more valuable it is
  3. Clarity: Diamonds can have tiny imperfections called inclusions, like birthmarks. Clarity measures how clear or flawless a diamond is. The fewer inclusions, the higher the clarity grade and value
  4. Carat Weight: This is simply the weight of the diamond. Larger diamonds tend to be more valuable, but all the other factors also play a role in determining a diamond's worth. These 4Cs of a diamond help determine diamond quality and price.
