Tiffany & Co.

Every step of the way, on #EarthDay and every day. All of the rough diamonds we source are in line with Tiffany’s superlative standards, including our commitment to protecting the earth in environmentally and socially responsible ways. We now provide provenance information—region or countries of origin—for every newly sourced, individually registered diamond we set. Because there should be nothing opaque about a Tiffany diamond.
