History and General Lapiz Lazuli Information

Blue Lapic Carving The name lapis lazuli is derived from a Latin word ‘Lauzulus’ that means blue stone. Its name may also have an early influence from the Persian word ‘Lazhuward’ and the Arabic word ‘Lazaward’, both of which mean blue. 
The relation between this intense natural blue gem and man goes way back 6500 years in history. The Egyptians have known to use this gemstone as early as the 3100 B.C. in inlay work, as beads and in lapis pendants. Natural lapis was also used as grounded power in medicines and as eye shadow in cosmetics. The Medieval builders used it in inlay work and mosaics that were created on the walls in their cathedrals. Renaissance painters used it to make an expensive ‘ultramarine’ natural blue color that was used in painting. This was done to give brightness and stability to the pictures.Natural Blue Lapis with Calcite Inclusions

Treatments done on Lapis LazuliNatural Blue Lapis with Calcite Inclusions

There are various treatments that are carried out on this gemstone. These are dying, waxing oiling and plastic impregnation that gives it a polished look. Out of these, dying is the most common treatment. Dying enhances the color of the gem temporarily. The color can actually come off when the gem is rubbed with a nail polish remover. The effect caused by waxing and oiling treatments can deteriorate when the gem is exposed to heat or sunlight. Since the practice of treating a lapis lazuli to get the deep blue natural hue is fairly common, it is always advisable to get the gem tested from a reputed gemological laboratory before actually making the purchase.

Other common gemstones which are sold in the market as lapis are synthetic sintered spinel produced in Germany, paste (or glass) with spangles of copper crystal inclusions, sodalite and blue dyed chalcedony. In Ancient Egypt blue lapis imitations were colored with copper sulfate to achieve the special deep blue color.
