At any time, our customers may have the opportunity to upgrade the Hannon diamond for one of greater worth. We will issue full credit for your original diamond with proof of purchase and verification of original quality, condition and personal ownership. The price for the new diamond must be at least fifty percent higher than the price of the original stone. All original laboratory reports are required. This policy does not apply to mountings or Laboratory Grown Diamonds.

For as long as you own your jewelry from Hannon, we will provide a complementary cleaning and inspection of your jewelry on regular basis. We recommend to our customers to bring us your pieces at least twice per year for this free service. This does not include the cost of any repairs needed.
