BA.sg Upgrade Guidelines


  • All GIA graded diamonds and IGI graded labgrown diamonds purchased in-store from BA.sg are eligible.
  • Your diamond will be valued at a maximum of 100% of the original purchase price if it was purchased within 2 years (Cap at 70% between 2 – 3 years, 50% for more than 3 years).
  • The price of the new diamond must be at least twice the price of your diamond.
  • Your diamond must be in its original condition with the original diamond grading report.
  • Any damage to your diamond will disqualify 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 for a minimal charge.
  • If your original setting cannot be reused, you have the option of keeping the setting or accepting a credit as determined by BA.sg.
  • If the original diamond was not set by BA.sg, it has to be dismounted first for the upgrade assessment.

Diamond Grading Reports:

  • The original diamond grading report must be returned in reusable condition. Fees may apply for any damaged reports.
