Deep in the riverbeds of Aotearoa New Zealand’s South Island, you’ll find a stone that’s as hard as steel and as green as the first breath of the earth. It’s called pounamu, or nephrite jade. It’s been formed into everything from adzes to earrings, including hei tiki, greenstone pendants handed down in Māori families for generations. Meet a pair of hei tiki—one with two hundred years of family history, and one that's being brought back to life in The Met. From their start as colonial institutions, you'll hear about the role museums can play in setting taonga, or treasures, free.
