What is my loose diamond worth?

There is no one set price for a loose diamond: there are over 20 characteristics that determine its value. At WP Diamonds our GIA trained team has decades of experience in pricing pre-owned diamonds based on the second-hand market. Some of the key areas we look at to ascertain a price include:

  1. The 4 Cs: carat weight, cut grade, clarity and color grade
  2. Diamond Certification: Some diamond grading laboratories are more reliable than others
  3. Damage: We look for chips or abrasions as these affect the price, especially if the diamond has to be recut as a result
  4. Diamond Buyer: Your return percentage of the retail price will depend on the diamond buyer you choose to work with
  5. Diamond Shape: Some diamond shapes are more in demand than others
