Packages accepted and/or signed for by a doorman or building representative, are considered to be a confirmed delivery, and therefore liabilities will rest between the recipient and the individual that accepted and/or signed for your parcel, not with Gemological Resources, Inc.

Packages left at an address because the recipient has a "Signature Release" on file with the shipper, are considered to be a confirmed delivery, and therefore our liabilities for safe delivery guaranteed cease and you assume the liability when we have delivery confirmation from the shipper. We highly recommend you check with FedEx and UPS to make sure you DO NOT have a "Signature Release" on file. Our liability terminates once a package is confirmed as delivered by the shipper, and this includes packages left at an address because the recipient has such a "Signature Release" on file with the shipper.


Gemological Resources, Inc. is not responsible for customer owned diamonds or gemstones, loose or set. No gemstone, including a diamond, can be guaranteed not to break, chip, scratch, or fracture. We therefore DO NOT guarantee that a diamond or gemstone, after the date of delivery, will not chip, break, scratch, or fracture, and as a result become loose and/or fall out. We strongly suggest insuring your jewelry items with a homeowners or private insurance policy that covers loss and/or damage to jewelry, should damage or loss occur.

If you send us your diamond(s) or gemstone(s), for any reason, we will treat the item with the greatest care possible and maintain safe storage when the item is not undergoing inspection and/or work.

In the event we receive a diamond and/or gemstone that is damaged, chipped, broken, or has large inclusions or imperfections, we will inform the customer and return the item to you.

Gemological Resources, Inc. has a zero-tolerance policy toward conflict diamonds. Measures such as the Kimberley Process, which tracks diamonds from mine to market, are employed by the industry in partnership with the United Nations, governments, and non-governmental organizations, police diamond exports to prevent the trade of illegal diamonds.

We only purchase diamonds through the largest and most respected suppliers who, like us, proudly adhere to and enforce the standards established by the Kimberley Process. If any of Gemological Resources Inc.'s suppliers was ever found to be in violation of that process, Gemological Resources, Inc. would immediately sever that relationship. We will continue to support and promote any process that works to uphold legitimacy in the diamond trade.
