Lapis Lazuli is a gemstone that has existed since the beginnings of time. The ancient Egyptians used it in their scarabs, pendants and other ornamental objects. The famous golden sarcophagus of King Tut was heavily decorated with Lapis Lazuli stones and Lapis Lazuli jewellery.
Lapis Lazuli contains Lazurite, the main constituent, mottled with white calcite and beautiful brassy pyrite.
Today, mines in northeast Afghanistan are still the major source of lapis lazuli. Important amounts are also produced from mines west of Lake Baikal in Russia, and in the Andes mountains in Chile. Smaller quantities are mined in Italy, Mongolia, the United States, and Canada.
The vibrant hue of the Lapis Lazuli has attracted people since time immemorial. Rich in antiquity, this semi-precious display stone is a must-have for your stone collection. The stone has a beautiful blue texture, accentuated with gold specks. Lapis was used in ancient times for making ornaments. Having a piece of stone at your home that has travelled through time is definitely a marvellous experience. It not only increases the visual appeal of your home, but it also works as a beautiful charm that reminds you of the bygone days from the pages of your history books.
