LAPIS LAZULI GEMSTONE INFORMATION
Lapis lazuli is one of the few gemstones that is a rock rather than a mineral. It can consist of up to 15 minerals, but is mainly is a mixture of 3 main components: Lazurite, a complex mineral containing sulphur, is the essential ingredient and gives the vivid blue colour, the others are Hauyne and Sodalite. To varying order degrees also Calcite, responsible for the white streaks in many specimens and Pyrite, an iron sulphide, gold/white in colour that gives the distinctive gold flecks.

Quality of Lapis Lazuli: Collectors look for a minimum of white calcite streaks, which in lower grade stones can give a lighter blue hue known as lapis matrix or ‘denim lapis'. Decorative and attractive gold flecks of pyrite are valued by collectors.

Fakes and enhancements of Lapis Lazuli: Synthetic Lapis has been produced since the 1950's. It is much harder than natural Lapis so can be easily distinguished. Also watch for cheaper priced perfectly coloured Lapis; it may be re-constituted in a similar way to turquoise. It can also be died and then waxed to improve the colour. It will still look very attractive, but the price should (but not in all cases) reflect the quality. Beware!

History of Lapis Lazuli: Many fine examples exist of Egyptian jewellery with Lapis set in gold, often in the popular scarab design. Historians believe that Cleopatra used powdered Lapis for eye shadow. The ancient royal Sumerian tombs of Ur, located near the Euphrates River in lower Iraq, contained more than 6,000 intricately carved Lapis Lazuli statuettes. Powdered Lapis was also the source for the blue pigment known as ultramarine, used by painters from the medieval period through the Renaissance. The name ‘lapis' is Parsi (Persian) for blue.

Care of Lapis Lazuli: A fairly soft and porous stone, protect it from solvents and chemicals. It is sensitive to pressure and high temperatures. Do not expose it to steam cleaners and always wipe off perspiration and perfume before storing. Warm soapy water is the best way to clean it.

Working with Lapis Lazuli: It is often identified by its strong smell, which indicates to professional cutters the potential depth of colour. The stone has an uneven fracture and an imperfect cleavage; however the tight granular structure makes it ideal for carving or sawing. A versatile material for different surface polishes.
Location and deposits of Lapis Lazuli: The finest gems come from the Badakhshan province of northern Afghanistan, where it has been mined continuously for over 6,000 years. Other deposits have been found in Angola, Canada, Chile, Myanmar, Pakistan, Russia and the United States.
