The GHM diamond upgrade policy gives customers a path to move into a larger or higher-value natural diamond over time. The exact credit depends on the type of diamond originally purchased.
GHM recommended diamonds
GHM recommended natural diamonds may be exchanged at full credit toward a replacement natural diamond worth at least twice the original purchase value.
Non-recommended diamonds
For non-recommended GHM natural diamonds, the policy applies a reduced credit value. The source page gives an example where a stone purchased for $1,000 would provide $700 in upgrade credit toward a diamond valued at $2,000 or more.
Important timing
The upgraded diamond purchase must be made the same day the upgrade is initiated. Customers should contact GHM before planning an upgrade so the team can confirm eligibility and current terms.
