Lifetime Trade-Up Policy
Every natural, laboratory graded diamond purchased from RDI comes with our Lifetime Trade-Up.
RDI Diamonds, Inc. was the originator and continues to offer THE EASIEST, MOST FLEXIBLE Trade Up Policy in the diamond industry.
That means an undamaged diamond can be upgraded at any time, towards another diamond of equal or greater value. (New diamond needs to be at least $1.00 more than original diamond). Original, undamaged, laboratory paperwork must accompany returned diamond to be eligible for trade.
Lab grown diamonds can be traded for lab grown diamonds on a 1 for 1 trade (new diamond must be $1.00 more than the original diamond). Trade in values will be determined by RDI Diamonds, Inc. current selling price. All diamonds and paperwork must be undamaged and complete for trade eligibility.
