Pounamu — greenstone — is the sacred nephrite of New Zealand's South Island, carved by Maori into hei-tiki pendants, toki adzes, and mere clubs treasured as taonga across generations. The dominant kawakawa variety is a near-black dark green with deep translucency and a glassy, polished sheen.

This design system renders that single stone tonally: the deep kawakawa body is the ground itself, not a backdrop. Carved koru spirals and grooves catch the light as lighter green highlights across one cool, monochrome nephrite surface — one stone, many depths.
