The Lazurite Group is a collection of minerals primarily known for their vibrant blue color, which is most famously represented by the mineral lapis lazuli. This group includes minerals that share similar chemical compositions and crystal structures, often containing elements like sodium, aluminum, and sulfur. Lazurite itself is the key mineral in this group and is prized for its use in jewelry and decorative items. The presence of other minerals, such as calcite and pyrite, can enhance the beauty of lapis lazuli, making it a sought-after material in art and ornamentation throughout history.
