Lapis Lazuli

Lapis lazuli is a gemstone of the kind that might have come straight out of the Arabian Nights: a deep blue with golden inclusions of pyrites, which shimmer like little stars.

This opaque, deep blue gemstone has a grand past. It was among the first gemstones to be worn as jewelry and worked on. At excavations in the ancient centers of culture around the Mediterranean, archaeologists have again and again found among the grave furnishings decorative chains and figures made of lapis lazuli – clear indications that the deep blue stone was already popular thousands of years ago among the people of Mesopotamia, Egypt, Persia, Greece and Rome. It is said that the legendary city of Ur on the Euphrates plied a keen lapis lazuli trade as long ago as the fourth millennium B.C., the material coming to the land of the two great rivers from the famous deposits in Afghanistan. In other cultures, lapis lazuli was regarded as a holy stone. Particularly in the Middle East, it was thought to have magical powers. Countless signet rings, scarabs and figures were wrought from the blue stone which Alexander the Great brought to Europe. There, the color was referred to as 'ultramarine', which means something like 'from beyond the sea'.

The most expensive blue of all time

The euphonious name is composed from 'lapis', the Latin word for stone, and 'azula', which comes from the Arabic and means blue. All right, so it is a blue gemstone - but what an incredible blue! The worth of this stone to the world of art is immeasurable, for the ultramarine of the Old Masters is nothing other than genuine lapis lazuli. Ground up into a powder and stirred up together with binding-agents, the marble-like gemstone can be used to manufacture radiant blue watercolors, tempera or oil paints. Before the year 1834, when it became possible to produce this color synthetically, the only ultramarine available was that valuable substance made from genuine lapis lazuli that shines out at us from many works of art today. Many pictures of the Madonna, for example, were created using this paint. But in those days, ultramarine blue was not only precious and so intense that its radiance outshone all other colors; it was also very expensive. But unlike all other blue pigments, which tend to pale in the light, it has lost none of its radiance to this very day. Nowadays, the blue pigment obtained from lapis lazuli is mainly used in restoration work and by collectors of historical paints.

The stone of friendship and truth

Lapis lazuli is regarded by many people around the world as the stone of friendship and truth. The blue stone is said to encourage harmony in relationships and help its wearer to be authentic and give his or her opinion openly.

Lapis lazuli is an opaque rock that mainly consists of diopside and lazurite. It came into being millions of years ago during the metamorphosis of lime to marble. Uncut, lapis lazuli is matt and of a deep, dark blue color, often with golden inclusions and whitish marble veins. The small inclusions with their golden shimmer, which give the stone the magic of a starry sky, are not of gold as people used to think, but of pyrites. Their cause is iron. The blue color comes from the sulphur content of the lazurite and may range from pure ultramarine to a lighter blue. At between 5 and 6 on the Mohs scale, this stone is among the less hard gemstones.

When the cutter turns up his nose ...

Many a cutter 'turns up his nose' when cutting lapis lazuli, for as soon as the stone comes into contact with the cutting-disc it gives off a typical smell. An experienced cutter can even tell from the odor how intense the color is. When polishing this stone, he must handle it gently on account of its modest hardness and not subject it to much pressure. But there is no need for the wearer to worry: a lapis lazuli that has grown matt from having been worn too much can easily be repolished at any time. Lapis lazuli is often sealed with colorless wax or synthetic resin. As long as these substances are not mixed with any coloring agent, this sealing process simply has the effect of improving the stone's wearing qualities. Having said that, the stone should always be protected from acidic substances, and it should not be exposed to too much sunlight.

As they did more than 5000 years ago, the best raw stones still come from the steep Hindu Kush in the northeast of Afghanistan. The lumps of blue rock, extracted from the inhospitable mountains by blasting, are brought down into the valley in the summer months by mules. Nature also created deposits in Russia, to the west of Lake Baikal, and in the Chilean Andes, where the blue rock often has white or grey lime running through it. In smaller amounts, lapis lazuli is also found in Italy, Mongolia, the USA and Canada, Myanmar and Pakistan, but in really good qualities it is rare all over. That is why the prices of jewellery with lapis lazuli vary very widely, from luxurious to quite inexpensive. The prices of this gemstone are largely dependent on the beauty and intensity of the color. The most popular is an intense, deep blue. Women with a pale complexion, however, often prefer the lighter shades of blue. Finely distributed crystals of pyrites, which shimmer in gold and look like sequins, will increase the value of the gemstone, whilst a restless, rough or blotchy grain will reduce it.

Lapis lazuli is a versatile and popular gemstone which has shown extraordinary stability in the turbulent tides of fashion. No wonder, since it has fascinated both men and women for thousands of years with its fabulous color and those golden points of light formed by pyrites.
