A Metamorphic Schist from Central Otago near Arrowtown a Queenstown favorite. A uniformly light grey stone with many linear quartz lines with very few occasional light brown tones where the stone has oxidised which can be hand selected out if required. It has an silver/shimmery effect and is the favorite of many New Zealand stonemasons due to its natural grain. When it is split down to a thin profile and laid in a tight dry-stack style it can be very eye catching and contemporary, as seen in the enlarged photo.
