Diamond Quality and Selection

How can I understand the differences in diamond quality?
To understand the differences in diamond quality, you can focus on the following characteristics:

  • Cut: The diamond's internal facets and how it's cut will affect its brilliance and sparkle.
  • Color: Diamonds can range from colorless to fancy colored. Good diamonds will have bright and clear colors, measured on a scale from D (colorless) to Z (fancy colored).
  • Clarity: Diamond clarity refers to the presence of inclusions and blemishes within the stone. Cleaner diamonds will be more valuable.
  • Carat: The weight of the diamond, with larger diamonds generally being more valuable.
