Diamond Upgrade Policy
MiaDonna is proud to offer a comprehensive and extremely competitive upgrade policy on its lab-grown diamonds and Diamond Hybrid®.
Any lab-grown diamond purchased from MiaDonna can be exchanged for credit equivalent to the original purchase price for a new lab-grown diamond that is at minimum two (2) times greater the value.
In order to be eligible, the lab-grown diamond being upgraded must be accompanied by the original documentation and must be in saleable condition. Any damage to the original diamond will disqualify the diamond from our upgrade program. The original grading report must be returned in reusable condition. Fees may apply for any damaged reports.
Upgrading to a Diamond Hybrid: Any Diamond Hybrid purchased from MiaDonna can be exchanged for credit equivalent to the original purchase price for a new Diamond Hybrid® that is at minimum half carat larger in size. For example, if you have a 1.0ct Round Cut Diamond Hybrid® you would need to upgrade to at least a 1.5ct to be eligible.
Upgrading to Lab-Grown Diamond: Any Diamond Hybrid purchased from MiaDonna can be exchanged for credit equivalent to the original purchase price for a new Lab-Grown Diamond that is of equal or greater value.
In order to be eligible for either upgrade, the Diamond Hybrid being upgraded must be in original condition. Any damage will disqualify the Diamond Hybrid® from our upgrade program.
- Upgrades are not available for colored gemstones, settings and/or jewelry.
- Upgrade credit does not include duty, shipping charges, or tax paid on the original purchase. All applicable duties, shipping charges, and taxes will be charged on the full retail price of the new stone before any credit is applied.
- Associated costs to set a new stone in your existing setting will be provided at time of upgrade.
- Some settings cannot accommodate a larger stone and will need to be remade in order to do so.
- Active discounts and/or promotions cannot be applied to upgrade orders.
- Upgraded stones that have been purchased and set are not eligible for return or exchange.
