LAPIS LAZULI POINT
Lapis Lazuli Point. A lightly polished Point of Lapis Lazuli, the “Stone of Royalty”. Lapis lazuli has been mined in Afghanistan for over 5000 years and remains highly sought-after to this day. This point shows the characteristic beautiful deep blue, pyrite and calcite inclusions. It also shows great banding and you can see the individual minerals easily. Lapis is always in demand and well appreciated as a gift.

Lazurite: Na, Ca8Al6Si6O24S, SO4. Sodium Calcium Aluminum Silicate Sulfur Sulfate.
Lazurite is a popular but generally expensive mineral. Well-formed, deep blue crystals are rare and valuable. It is more commonly found massive and combined with other minerals into a rock called lapis lazuli. Lapis lazuli or lapis for short is mostly lazurite but commonly contains pyrite and calcite and some other minerals. The name means “blue rock” and is always a brilliant blue with violet or greenish tints. The rich blue coloor is due to the sulfur that is inherent in the structure of lazurite. Small crystals of pyrite are always present in lapis and their brassy yellow coloor is both attractive and diagnostic in distinguishing lapis from its also blue cousin – sodalite rock, which lacks pyrite.
