From scintillating white granites to brilliant serpentines - reds,
greens, maroons, greys, yellows, and vibrant oranges - the stone
of Zimbabwe is a visual catalog of incredible mineral wealth. More
than 250 specific ores and combinations of serpentine have been
identified in Zimbabwe. It is the complex combination of these minerals
that create the colorful palette so unique to Zimbabwean carving
stone.
The most
common carving material is serpentine, at 2.0 to 5.5 on the Mohs
hardness scale. The much harder granites, and ancient brilliant
green verdite(3.6 billion years old), approach 9.0- a hardness rivaling
that of rubies. Verdite, also known as Africa's Green Gold, is particularly
prized by some artists for its rich, deep emerald color and swirling
striations.
Many of the carving stones come from the Nyanga Mountains or near The Great
Dyke, a volcanic ridge running 310 miles through the countryside
and the longest linear mass of volcanic rock in the world. The 2.5
billion-year-old hills of The Great Dyke are laced with chrome,
platinum, gold, copper, emeralds, and other precious metals. Heat
and pressure have been applied to this ancient rock mass over the
years, creating unusual mineral assemblages that are reflected in
the tremendous variety of colors, shadings, and combinations of
stone. Once believed to be the repository of the wealth of legendary
Ophir, the dyke never yielded the dreamed-of mountains of gold.
However, exquisite carving stone is plentiful in this region.
After quarrying the raw stone with pickaxe and pry bar, carvers
begin the creation process
with handmade tools to release the spirit trapped within the stone.
