Round Bright Cut Diamond (with rotating animation)
Diamond refers to the diamond after pondering, diamond is a natural mineral, is the original stone of diamond. Simply speaking, diamond is a kind of elemental crystal composed of carbon formed under the condition of high pressure and high temperature in the deep part of the earth. Diamonds are the hardest natural substance known in the world. Diamond production is rare, usually colorless crystals, with a high degree of refractive properties, can reflect a colorful luster. Diamonds can be used not only as jewelry, but also as advanced cutting and grinding materials in industry.
Crystal structure of diamond
Diamond (Diamond) is an atomic crystal with a cubic crystal system composed of carbon (C) elements, and its structure is one of the hardest natural materials in nature. Crystal system cubic crystal system (equiaxed crystal system) space group Fd3m (face centered cubic structure) unit cell parameter a ≈ 3.57 Å (unit cell edge length) The number of atoms in each unit cell is 8 carbon atoms, and each carbon atom is connected to another 4 carbon atoms through covalent bonds to form a tetrahedral configuration. All carbon atoms are located in the apex and face-centered positions of the cubic unit cell, as well as the four inner positions (alternating distribution).
spinel crystal
Spinel (Spinel) is a beautiful and durable gem mineral, which usually occurs together with the marble parent rock (Marble matrix), forming a unique ore combination. The chemical composition of spinel is magnesium aluminum oxide (MgAl₂ Ogo), which has a variety of colors, from red, blue, green to colorless. Spinel crystals have a high degree of transparency and a bright color, usually in the shape of octahedra or rhombohedra.
UV-irradiated ruby
Ruby (Ruby) is a gem-grade corundum mineral variant, the chemical composition of alumina (Al₂ O), its unique red is due to the crystal structure contains trace amounts of chromium. Ruby is a very hard and durable gemstone, with a hardness of on the Mohs scale, second only to diamonds. The color of ruby ranges from pink to deep red, and the intensity of the color depends on the amount of chromium in the crystal structure. Ruby usually exhibits a hexagonal crystal structure, and the crystal is usually prismatic with a flat base end face. Due to its beautiful color and high hardness, rubies are widely used in jewelry, such as rings, necklaces and bracelets.
Polished Amethyst
Polished amethyst is a popular gemstone specimen. Amethyst is a purple variety of quartz that ranges in color from light purple to dark purple and is determined primarily by the presence of iron and other trace elements. Quartz is a common mineral with the chemical composition of silicon dioxide (SiO₂), which is widely found in the earth's crust. Polished amethyst and quartz are often used in jewelry and ornaments because their luster and beautiful color make them very attractive.
Opal stone
Opal, as a gemstone, is a hydrate of silicon dioxide with a chemical composition of SiO2 · nH2O. It has an amorphous structure and therefore does not have a specific shape. Its fracture surface is shell like, mainly formed by the colloidal precipitation of silicon dioxide. In mineralogy, it belongs to the opal class and contains two types of gemstones: variable color and invariant color. It is a hydrated amorphous silica.
