In the mountains and valleys of Golden Bay, unusual coloured stones have been noticed, collected and valued for generations. Follow the stories, old reports and geological clues that lead to Obay polychrome schist and discover how bands of green, blue and brown became part of a much older story written into the landscape.

In 1906, visitors to New Zealand’s West Coast encountered a striking green stone and confidently called it malachite. Others later called it amazonite. Neither name was right. Follow the old newspaper reports, river valleys and geological investigations that revealed Aotea as a rare rock of fuchsite, kyanite and quartz, and uncover a story of mistaken identities, surviving names and deep geological history written into stone.

In 1891, a miner on New Zealand’s West Coast pointed out an unusually hard boulder. Inside were rubies, the beginning of a geological mystery that has lasted more than a century. Follow the miners, geologists and scientists who tried to trace Goodletite back to its source, and discover how a strange green and red rock came to preserve a story of glaciers, vanished landscapes and extraordinary processes deep beneath the Southern Alps.
