Rose quartz is a pink or pale pink mineral. Its molecules are comprised of one atom of silicon and two atoms of oxygen. The mineral may be opaque or translucent, and it has a hardness of seven, with 10 being the hardest mineral known to humankind. Rose quartz forms when magma deep in the Earth's crust cools, and the mineral rises closer to the surface.Know More
Other physical properties of rose quartz include a specific gravity of 2.65, an index of refraction of 1.54 and a vitreous luster. Individual grains of crystals are distinguishable, which means rose quartz is a macrocrystalline variety of quartz. Some gemstones have rutile crystals aligned 120 degrees apart to form a star-like shape within the mineral. This effect is called asterism.
Rose quartz is the state mineral of South Dakota. The rock is mined in the Black Hills region near the town of Custer. Maine also has rose quartz mines. The pink silicate is primarily found in Brazil, but veins also exist in South Africa, Madagascar, Mozambique, India and the United States.
Rose quartz is used in jewelry, landscaping pieces, tile and lapidary work. The mineral is usually colored naturally and not treated. It's traditionally a symbol of love and beauty.Learn more about Atoms & Molecules
Some physical properties that metals have in common are that they have luster, good thermal and electrical conductivity, high densities and melting points and are malleable. With the exception of mercury, most metals also are solid at room temperature.Full Answer >
The ability of carbon atoms to form covalent bonds with other carbon atoms is the most unique of its bonding properties. This enables carbon to form long, continuous chains, branches and loops consisting of carbon and hydrogen in hydrocarbons and only carbon in carbon allotropes such as C60.Full Answer >
The properties of water include miscibility and condensation, cohesion and adhesion, high surface temperature, high heat capacity, heat of vaporization, capillary action, varying density, electrical conductivity and compressibility. Water is colorless, odorless and tasteless. In nature, it exists as a liquid, solid and gas. Pure water boils at 212 degrees Fahrenheit and freezes at 32 degrees Fahrenheit.Full Answer >
