Limestone. Limestone, a sedimentary rock abundant in New Zealand, consists mainly of the bones and shells of tiny marine fossils made of lime (calcium carbonate). Rocks with more than 50% calcium carbonate are considered to be limestone. Most New Zealand limestone deposits formed in the Oligocene and Miocene periods, 537 million years ago.

Wet the Stone. Limestone is formed in water, and wetting it makes it more malleable. It may be more prone to breakage, which is good for carving but can be detrimental to the overall shape. Check for cracks in your stone prior to wetting it, as those cracks indicate where pieces could break off when wet or being carved.
