Fancy yourself a green Holly Golightly? Hop in a cab and get thee to Tiffany's to calm the nerves and buy diamonds from an industry heavy hitter with a reputation as a leader in sustainable business practices. Not only does the company support environmentally and socially sound mining, but it also only acquires diamonds from countries that fully cooperate with the Kimberly Process and are documented as conflict-free. Additionally, Tiffany's has its own foundation that backs environmental conservation and is partnered with groups such as Oxfam and Earthworks.
