  3. Are there any chips or abrasions? This will affect the price especially if a diamond has to be recut to remove them
  4. Your return % of the retail price will depend on the buyer your select and what kind of deal you got when it was purchased
  5. Is the shape of your stone hot in the market? Are the characteristics of your stone desirable in the market? Not easy to know but a reputable buyer will be able to advise
