|Head by Sylvester Mubayi Nyamuziwa. I am inadequate to comment on a Master piece by a world renowned artist. The sculpture speaks for itself. Sculpted in Springstone which is a very hard serpentine with high iron content and a fine texture, no cleavages, hard and firm offering a good resistance to the sculptor. Springstone has a rich outer blanket of reddish brown oxidised rock. They emerge from the quarry like sculptures created by nature millions of years ago and are often a source of inspiration to the artist. There are a few mines where this stone is found, but Guruve, in the north, is where springstone is mined. A beautiful dark stone, it polishes to a high shine because of itâ€™s density. As with most other stones that are mined for the purpose of sculpting, this stone is mined by hand on communal lands. Springstone Mohâ€™s hardness is 7-8.
