Quartz becomes more opaque or milky due to the presence of inclusions, such as tiny gas bubbles, liquid, or other minerals trapped during its formation. Additionally, the process of irradiation can alter its crystal structure, leading to a milky appearance. Chemical impurities or alterations during metamorphism can also contribute to this opaqueness. Overall, these factors affect the light transmission through the crystal, resulting in a more opaque or milky quality.

Yes, quartz has been discovered on the moon. Apollo astronauts found small amounts of quartz in the lunar soil samples they brought back to Earth. The presence of quartz on the moon indicates that it shares some geologic similarities with Earth.

Quartz comes in a wide range of colors including white, clear, pink, purple, blue, yellow, brown, and black. The color variations are due to different impurities present in the quartz crystal structure.
No, opal is not quartz. While both are considered silicate minerals, opal is a mineraloid that lacks a crystalline structure, whereas quartz is a crystalline mineral with a defined chemical composition of silicon dioxide (SiO2). Opal is primarily composed of hydrated silica and can form in various colors and patterns, making it distinct from quartz.
A cacholong is an opaque or white form of chalcedony, a variety of quartz.

Covalent crystals are not necessarily opaque. Think of diamond, pure quartz crystals, pure aluminium oxide crystals these all are colorless and transparent.
Sand is made up of small grains of minerals such as quartz and feldspar, which have the property of scattering and absorbing light rather than letting it pass through. This scattering and absorption of light by the grains causes sand to appear opaque to our eyes, as very little light is able to pass through the material.
Cloudy quartz is a type of quartz crystal that has a cloudy or opaque appearance due to the presence of microscopic inclusions or imperfections. It differs from other types of quartz, such as clear quartz or rose quartz, in its visual appearance and energy properties. Cloudy quartz is believed to have a grounding and stabilizing effect, helping to bring clarity and balance to the mind and emotions.
Quartz transparency refers to how much light can pass through a quartz crystal. It is measured on a scale from opaque (no light can pass through) to transparent (light can pass through easily). Quartz is known for its high transparency, making it a popular choice for gemstones and optical applications.
A very large number if the rock forming minerals allow the transmission of light if sliced thinly enough. Some others are translucent at larger scale for example quartz and calcite. However in most rocks the size of the clasts or crystals is too small or the presence of gas inclusions or other elements causes them to become coloured, cloudy or otherwise opaque. It is possible that it may be possible to see through a pegmatite (pegmatites are a rare type of very coarsely crystalline intrusive igneous rock) if the crystals are large enough. As such in the vast majority of cases naturally occurring rocks are opaque and can not be seen through.
Quartz is harder than calcite, making it more scratch-resistant. Quartz also has a higher melting point than calcite. Additionally, quartz is typically transparent or translucent, whereas calcite can be transparent, translucent, or opaque.

Halite typically forms cubic crystals with smooth faces, while quartz forms hexagonal prisms with pointed ends. Halite crystals are transparent and colorless, while quartz crystals can vary in color and are often translucent or opaque. Additionally, halite has a salty taste and is softer than quartz, which is a hard mineral.
Calcite is the opaque compound calcium carbonate (CaCO3). It will dissolve in carbonic acid and will fizz in stronger acids. Quartz is the usually transparent compound silicon dioxide (SiO2). It will not dissolve in acid.
