Lapis lazuli blue

The intense blue of lapis lazuli, one of the oldest and most coveted gemstones, has fascinated civilizations for millennia.

About this subject

Lapis lazuli is a metamorphic rock composed mainly of lazurite, a silicate mineral that gives it its characteristic blue color, along with calcite and pyrite. It forms in contact metamorphic environments, with the Sar-e-Sang mines in Afghanistan being the most famous and ancient, having been in operation for over 6,000 years. Since Ancient Egypt, lapis lazuli has been mined and used in jewelry, amulets, and sculptures, such as the well-known sarcophagus of Tutankhamun. During the European Renaissance, the stone was ground to produce ultramarine pigment, the most valued blue of the time, used in masterpieces like Vermeer's "Girl with a Pearl Earring" and Giotto's frescoes. Natural ultramarine pigment from lapis lazuli was as expensive as gold, reserved for religious themes and noble figures. Today, lapis lazuli is also mined in Chile, Russia, and Pakistan, but Afghan material remains the purest and most valued. Its hardness on the Mohs scale ranges from 5 to 5.5, requiring careful handling to avoid scratches. Beyond its use in jewelry, the stone is appreciated by collectors and in decorative objects such as spheres, sculptures, and inlays in furniture. The deep blue of lapis lazuli is often associated with royalty, wisdom, and truth, and is considered the stone of the throat chakra in spiritual practices.
