Lapis lazuli
(sometimes abbreviated to lapis
) is a deep blue
semi-precious stone
that has been prized since
antiquity
for its intense color.
Lapis lazuli was being mined in the
Sar-i Sang
mines and in other mines in the
Badakhshan
province in northeast
Afghanistan
as early as the
7th millennium BC
, Lapis beads have been found at
neolithic
burials in
Mehrgarh
, the
Caucasus
, and even as far from Afghanistan as
Mauritania
. It was used for the eyebrows on the funeral mask of
King Tutankhamun
(1341–1323 BC).
At the end of the Middle Ages, lapis lazuli began to be exported to Europe, where it was ground into powder and made into
ultramarine
, the finest and most expensive of all blue pigments. It was used by the most important artists of the Renaissance and
Baroque
, including
Massaccio
,
Perugino
,
Titian
and
Vermeer
, and was often reserved for the clothing of the central figure of the painting, especially the
Virgin Mary
.
Today mines in northeast Afghanistan are still the major source of lapis lazuli. Important amounts are also produced from mines west of
Lake Baikal
in Russia, and in the
Andes
mountains in
Chile
. Smaller quantities are mined in Italy, Mongolia, the United States and Canada.
Uses
Lapis takes an excellent polish and can be made into jewelry, carvings, boxes,
mosaics
, ornaments, and vases. It was also ground and processed to make the
pigment
ultramarine
, widely used during the
Renaissance
in
frescoes
and
oil painting
. Its usage as a pigment in oil paint largely ended in the early 19th century when a chemically identical synthetic variety became available
.
