Want to ask you the difference between lapis lazuli and lapis lazuli?

Lapis lazuli (English: from Latin) was called Yulin, Jinjing, Jinyu and Indigo in ancient China. Buddhism is called Prajnaparamita or Liuli. It belongs to one of the seven treasures of Buddhism. "Shiya" says: "Lapis lazuli is like the sky, or gold scraps are scattered and brilliant, if the stars are beautiful in the sky." Therefore, in ancient China, lapis lazuli was usually used as a symbol of the majesty of heaven. In the selection of lapis lazuli, it is best to have a beautiful Venus with uniform color and no cracks and delicate texture. If the pyrite content is low, the absence of Venus on the surface will not affect the quality. But if Venus is black, or there is too much calcite, forming a large area of white spots on the surface, its value will be greatly reduced. Lapis lazuli is a rare gem, and blue lapis lazuli cultural relics are often very precious. Lapis lazuli, also known as lapis lazuli, is a blue variety of sodalite. Lapis lazuli color is the body color of Tibetan Buddhist pharmacist Buddha. Wearing it often can ensure peace and health, and there is no disease or disaster. Zhang, a famous geologist in China in modern times, wrote in the book Cliff that "lapis lazuli is like the sky, or the gold scraps are exhausted, brilliant as the stars and beautiful as the sky." Therefore, the ancients honored lapis lazuli as "fairy stone" and regarded it as a treasure of heaven. According to the research in Qing Dynasty, "the emperor wore lapis lazuli to decorate the Temple of Heaven." Lapis Lazuli, the English name of Lapis Lazuli, comes from Latin lapis lazuli, the former means gem and the latter means blue (gem). Its handicrafts are called "green gold", and in ancient times they were called "resplendent and magnificent", "generational" or "Bi Liuli". Celestite is a kind of crystal, and its chemical composition is SrSO4 _ 4, which belongs to orthorhombic sulfate mineral. Celestite is mainly used for making strontium carbonate and producing TV picture tube glass. Its colors are blue, green, yellow-green, orange, light blue-gray, and sometimes colorless and transparent. Aijingshan celestite vein deposit in Liyang, Jiangsu Province is the largest strontium deposit in Asia. Celestite mineral name: celestite; Chemical composition: SrSO4, strontium-bearing ore [1]; Component Sr(SO4) contains 45% ~ 47% Sr and sometimes barium and calcium. [2]; (strontium, barium) sulfuric acid. Strontium content is greater than barium, and it can also contain elements such as lead, calcium and iron. Crystal system: Orthogonal crystal system Crystallization habits: plate-like or columnar and flaky crystals, rhombic biconical crystals, plate-like crystals. Perfect crystals are rare, mostly aggregates, which are stalactite-like, nodular, fibrous and fine-grained, and their colors are blue, green, yellow-green, orange or colorless; Light blue-gray, sometimes colorless and transparent. Gloss and transparency: glass luster, pearl luster on cleavage surface, transparent to translucent luster: biaxial crystal, positive refractive index:1.619 ~1.637; Birefringence 0.0 18 Polychromaticity: weak absorption spectrum: inconspicuous cleavage: cleavage parallel bottom {00 1} is complete, two groups of perfect cleavage, parallel rhombic column {2 10} medium. Mohs hardness: 3.0~3.5 Density: 3.97 ~ 4.0g/cm 3 Output: mainly produced in sedimentary rocks such as dolomite, limestone, marl and gypsum clay. It exists in hydrothermal deposits and sedimentary deposits. Uses: used for extracting strontium and preparing strontium compounds [3], making picture tube fluorescent screen, red fireworks and signal flares.
