Lapis Lazuli through the Ages


Lapis lazuli which is one of the oldest and best known of all gemstones has a history which can be traced back thousands of years. Along with the mineral turquoise this rich blue coloured metamorphic rock was highly sought after by some of the earliest civilizations including Babylonia, Ur and Ancient Egypt.  As well as being carved into amulets and talismans it was also used for jewellery and in religious ceremonies.  Carvings found in Ancient Egyptian tombs including that of King Tutankhamun date back 3000 years BC and one of the most famous artefacts which is his gold funerary mask not only features lapis lazuli but also white quartz, obsidian, turquoise, carnelian and coloured glass.

In the ancient world lapis lazuli was known as 'sapphirus' and was described by Theophrastus Ancient Greek philosopher (successor to Aristotle) and later by Pliny the Elder Roman author, naturalist and philosopher as "a blue stone with spots of gold that was never transparent."  The "spots of gold" which are iron pyrite (a relatively unknown mineral at that time) is one of several different crystalline minerals that make up lapis lazuli.  Stones with a more solid colour that didn't feature visible inclusions of pyrite were known as kyanos but it's believed the name is likely to have incorporated other dark blue coloured stones as well.  Pliny wrote that sapphirus included with spots of gold was not suitable for engraving which indicates the pyrite and possibly other minerals present were too hard to cut through.  Throughout history lapis lazuli has been confused for sapphire not because of the similarity in their colour but because it was once known as sapphirus.

Ultramarine was a highly sought after deep blue coloured pigment that was produced by grinding lapis lazuli down. Used in art and particularly paintings, it was popular from ancient times until 1826 when a synthetic alternative was invented. Some say Michelangelo's painting The Entombment was unfinished because he couldn't afford to buy ultramarine and Rafael is said to only have used it for the final coat of his paintings choosing azurite instead for the base layers because it was considerably cheaper.

In Ancient Egypt lapis was believed to open the heart to love and lead the soul into immortality.  In the Bible the Book of Exodus states that sapphirus was one of the twelve precious gemstones embedded in the breastplate of the Jewish high priest.

During excavations of the royal graves in the ancient Sumerian city of Ur artefacts featuring gold, silver and gemstones were discovered which exhibited incredible levels of craftsmanship, skill and artistry.  The wide range of materials indicated the presence of huge wealth and that an extensive network of trade must have been in place because many of the stones and metals were not found naturally in that region.  Sumer was located between the Tigris and Euphrates rivers in Mesopotamia which is modern day Iraq and was home to one of the earliest civilizations. Over 6000 items carved from lapis lazuli were found there and the stone used for these artefacts would most likely have come from the Badakhshan province of Northern Afghanistan.  From there it would have been transported to countries including Mesopotamia, Ur, Egypt and India.

This lyre bull's head which is crafted from gold and lapis lazuli was found in a king's grave during a British Museum expedition to Ur (modern day Iraq) in 1928.  It's a fine example of ancient Sumerian art and dates to approximately 3500 BC.  Further photographs can be found by following the link below.

Lapis lazuli has been mined from this same location in Afghanistan for over 6,500 years and the mines are some of the oldest in the world. Although there were once several in operation there is now just one called Sar E Sang which continues to provide some of the world's finest material.

 

 

More Lapis Lazuli Facts


Lapis lazuli is a metamorphic rock that can only be found in a few places worldwide because of the specific geological conditions required for it to form.  In recent years this has enabled historians to reconstruct some of the ancient trade routes.  Although often referred to as a mineral it's actually a rock because it's made up of several different minerals.  The inclusions of iron pyrite are actually in the mineral lazurite which is the main component and primary source of the stone's colour.  Other minerals present include sodalite and white calcite whilst diopside, enstatite, mica, hauynite and hornblende amongst others can also be found in certain specimens.  The finest grade lapis lazuli exhibits rich blue colour and can lack any visible trace of calcite or pyrite.

Lapis lazuli can also be found in Siberia and Chile and stones from Chile have been known to rival the quality of material from Afghanistan.  It can also be found a few other countries around the world but only in relatively small quantities. On Mohs scale of mineral hardness lapis lazuli grades 5 to 5½ so must be handled carefully because it can be scratched by many other materials.

In crystal healing it's said to be the key to spiritual attainment and can help expand intellectual capacity and awareness. It stimulates purity and clarity of mind and is a useful companion in the organization of daily life.  In Ancient Rome it was used as an aphrodisiac.
