How is the value of my diamonds determined?

Unlike gold and silver, diamond prices hinge on factors beyond purity and weight:

  • Shape: Diamonds come in two shapes: round (perfectly symmetrical) and fancy-cut (all other varieties). The shape of the diamond can affect its price, with round diamonds typically being more valuable.
  • Carat: The weight of the diamond, measured in carats, is also a significant factor in determining its value. Larger diamonds are rarer and can fetch higher prices.
  • Colour: The value of diamonds is graded on a scale from D to Z based on their colour. Coloured diamonds are graded separately.
  • Clarity: Clarity is evaluated by examining under x10 magnification to detect flaws. The higher the clarity score, the fewer blemishes are present.
  • Cut: The value of a diamond is impacted by its symmetry, polish, and proportions. A well-cut diamond reflects light brilliantly.

Remember, these are general guidelines. For an accurate quote, visit our store and let our experts evaluate it.

What documents do I need to sell my diamond?

To sell your diamonds securely, you’ll need to provide a valid government-issued photo ID, such as a driver’s licence or passport.
