All certified diamonds purchased from Hortensia By Delove are eligible for a 100% credit towards a new diamond that is at least double in value or more. Because we continually re-stock our inventory, a minimum three year period is required before we are able to accept your trade in. The diamond you are trading in must be first inspected by our gemologists to ensure it is in original condition, and accompanied by the original diamond certificate and sales receipt. If the current ring setting can still be used we will mount your new diamond at no additional cost. Should you require a new setting, you have the option of keeping the old setting or accepting a credit as determined by Hortensia By Delove.
