Greenstone Factory Shop is a gift shop on Mount Eden Road in Grafton, Auckland, rated 4.8, specialising in greenstone, or pounamu, going by the name. Genuine New Zealand pounamu is a taonga with cultural significance to Māori, and it's worth asking whether a piece is authentic NZ pounamu or an imported jade look-alike, since the two can look similar but differ a lot in value, origin and meaning. A factory shop often means carving happens on site or nearby, so there's a chance to see the process rather than buying a finished piece off a shelf, which adds a layer of authenticity a retail store can't offer. There's a long-standing custom that pounamu means more as a gift from someone else than as something bought for yourself, so it's worth keeping that in mind if choosing a piece for someone rather than a souvenir. On Mount Eden Road in Grafton, this shop is a local specialist in that greenstone trade.
