INTA Gems & Diamonds offers lifetime upgrading on any loose center diamond as long as the new purchase is at least 150% or greater in value from the original.
*After 30 days of purchase, the jewelry item is subject to inspection for any damages from the original sellable condition.
For all jewelry, a 15% restocking fee will apply for a diamond center of up to 3.00 carats.
All original paperwork must be accompanied with the upgrade. This includes its independent report (GIA or EGL certificate).
*This upgrade policy is subject to change at any time.
