The Lumera Quality Guarantee

Every GIA diamond purchased from Lumera is examined prior to shipment to ensure it matches the description provided online and in the diamond's accompanying certificate. Lumera guarantees that the diamond you receive will be exactly as represented in the GIA report. If it is not, Lumera will refund your entire purchase price, plus $100.

Every GIA diamond shown on Lumera is offered at a price lower than the typical retail price for a diamond of similar quality. Lumera guarantees that your GIA diamond will appraise for a retail value equal to or greater than the purchase price when appraised by a qualified, independent appraiser. If it does not, Lumera will refund the purchase price of your GIA diamond, plus $100.

You will receive this guarantee in writing with your GIA diamond purchase.
