It’s been an active week for the jewelry industry in New York City, where the JA New York, MJSA Expo and Lueur shows all happened at the Javits Center and others in the industry gathered at the Jewelry Industry Summit to talk about responsible sourcing and sustainability.

Meanwhile, one company unveiled the first pieces of platinum jewelry made using a 3-D printer and is displaying them at the Baselworld show, which opened Thursday.

De Beers announced the launching of its diamond reselling business in the United States and Blue Nile said that it would open its third brick-and-mortar location in the Washington, D.C. area by mid-summer.
