LAPIS
LAZULI : It is a
"rock", because it consists of an
association of minerals, lazurite and
variable quantities of calcite and
pyrite. Calcite gives it white colour,
Pyrite gives it golden colour and
Lazurite gives it blue colour. The
common term used for this gemstone in
the market is "Swiss Lapiz". It was one
of the first stones ever to be used and
worn for jewellery. Excavations in the
antique cultural centres all around the
Mediterranean provided archeologists
with samples for jewellery which was
left in tombs to accompany the deceased
into the hereafter. Again and again this
jewellery consisted of necklaces and
objects crafted from Lapis lazuli – the
clear indication that thousands of years
ago the people in Mesopotamia, Egypt,
Persia, Greece and Rome cherished deep
blue Lapis lazuli. It is reported that
at the legendary city of Ur situated on
the Euphrat river, there was a busy
trade in Lapis lazuli as early as four
thousand years BC. In those days the
stones were mined in the famous
occurrences in Afghanistan. But in other
cultures Lapis lazuli was also
worshipped as a holy stone. Especially
in the oriental countries it was
considered as a gemstone with magical
powers. Numerous seals, rings, scarabs
and objects were crafted from the blue
stone, which was introduced to Europe by
Alexander the Great. Here the colour was
called „ultramarine“, meaning „from
beyond the seas“. It is the most
valuable ornamental material. For many
people all over the world Lapis lazuli
is considered a stone of truth and
friendship. The blue stone is reputed to
bring about harmony in relationships and
to help its wearer being an authentic
individual who may openly state his or
her opinion. Lapis lazuli is a highly
appreciated stone suitable for many
purposes, which shows remarkable
stability ion the light of quickly
changing fashion trends. This is not too
surprising, after all, its fairy-tale
colour and its golden Pyrite light
reflections have been fascinating men
and women for thousands of years.
