Lapis lazuli is a rock, which means it’s an aggregate of several minerals. This ancient gem contains three minerals in varying amounts: lazurite, calcite, and pyrite. Sometimes, it also contains one or more of the following: diopside, amphibole, feldspar, and mica. Lapis frequently contains varying amounts of whitish calcite matrix—the host rock that surrounds the gem—or flecks or veins of glinting yellow pyrite, or both. The gem can also have a smoothly uniform bodycolor, free of visible pyrite and calcite. Lapis is semitranslucent to opaque, with a waxy to vitreous luster. It has fair toughness, and its hardness ranges from 5 to 6 on the Mohs scale, depending on the mix of minerals.
Variously described as indigo, royal, midnight, or marine blue, lapis lazuli’s signature hue is slightly greenish blue to violetish blue, medium to dark in tone, and highly saturated. In its most-prized form, lapis lazuli has no visible calcite, although it might have gold-colored pyrite flecks. Continue reading from Gemological Institute of America
Historians believe the link between humans and lapis lazuli stretches back more than 6,500 years. The gem was treasured by the ancient civilizations of Mesopotamia, Egypt, China, Greece, and Rome. They valued it for its vivid, exquisite color, and prized it as much as they prized other blue gems like sapphire and turquoise. Badakshan, a province in present-day Afghanistan, is a forbidding wasteland of mountains, bare of any vegetation. The sheer mountain faces rise as high as 17,000 feet, and are scored with treacherous ravines. Humans make their way there to seek one thing only: the azure treasure that is fine lapis lazuli. The same was true as far back as 700 BC, when the region was part of a country known as Bactria. The lapis mines that were producing then are still producing today. They are, in fact, the world’s oldest known commercial gemstone sources.
Merchant caravans transported their precious blue cargo across Bactria, on their way to the great cities of the ancient Greeks, Indians, Egyptians, Mesopotamians, and Persians. Marco Polo referred to the area’s lapis mines in 1271, but few outsiders have seen them because of their inhospitable location. For thousands of years, lapis has been fashioned to show off its rich, dark color. Typically, lapis used in jewelry has been cut into cabochons, beads, inlays, and tablets. But lapis lazuli’s use has never been limited to jewelry alone. It’s also a popular carving material. Throughout its history, lapis has been fashioned into practical objects, including game boards, bowls, dagger handles, hair combs, and amulets. Continue reading from GIA
In ancient times Lapis Lazuli was most highly regarded because of its beautiful color and the valuable ultramarine dye derived from it. Its name comes from the Latin lapis, "stone," and the Persian lazhuward, "blue." It is a rock formed by multiple minerals, mostly Lazurite, Sodalite, Calcite, and Pyrite, and is a rich medium to royal blue with gold flecks (pyrites). Lower-grade Lapis is lighter blue with more white than gold flecks and is sometimes called denim Lapis. Continue reading from Crystal Vaults
The Sumerians believed that the spirit of their gods lived within the stone, while the ancient Egyptians saw it as a symbol of the night sky. Since the earliest of times, lapis lazuli has been associated with strength and courage, royalty and wisdom, intellect and truth. From antiquity, lapis lazuli has been worn in the belief that it will ward off evil. In ancient Egypt, it was powdered and worn about the eyes to improve eyesight. Today, it is considered by some to be an aid to balancing the brow chakra (which influences vision and hearing). Imbalances of the brow (or blue) chakra are said to cause headaches, anxiety and disorders of the skin. Continue reading from Fire Mountain Gems

Historically speaking, crystals are touted as ancient forms of medicine, with philosophies borrowed from Hinduism and Buddhism. However, it’s important to know that there’s no scientific evidence to support the use of crystals. Despite this, people are still drawn to their colors and beauty. The key to indulging in this self-care experience is mindfulness, reflection, and acceptance. For instance, researchers found that a person’s mind may have much more healing power than it’s given credit. Continue reading from Healthline
