Although we all like to think that our diamond jewellery is forever, no woman would say no to an upgrade!
As the years go by, our tastes evolve and we aspire to larger or better diamonds.  
As part of our lifetime commitment to you, Gemma Stone is proud to provide a Diamond Upgrade Program on all certified diamonds. 
Please contact
  • All GIA certified diamonds purchased from Gemma Stone are eligible.
  • You will receive credit equal to 100% of the original price toward the purchase of a new diamond.
  • The price of your new diamond must be greater than the price of your original diamond.
  • Your diamond must be in its original condition with the original diamond grading report.
  • Any damage to the original diamond may disqualify the diamond from our upgrade program.
  • The credit value will be based solely on the value of the diamond.
  • If your setting fits your new diamond and is in reusable condition, we will set your new diamond in your original setting.
  • If your original setting cannot be reused, you have the option of keeping the setting or accepting a credit as determined by Gemma Stone.
  • Any diamond not originally set by Gemma Stone must be returned without the setting.
Diamond Grading Reports:
  • The original diamond grading report must be returned in reusable condition. Fees may apply for any damaged reports.
