Selenite is a crystalline form of gypsum, specifically a variety of calcium sulfate dihydrate (CaSO₄·2H₂O). It typically forms transparent, colorless to white crystals that exhibit a tabular or prismatic shape, often with a glassy luster. The crystals can also appear in fibrous or massive forms, and are known for their ability to cleave easily along specific planes. Selenite is commonly found in sedimentary environments and is often associated with evaporite deposits.

What is the streak of selenite?
Selenite, a transparent or translucent form of gypsum, has a white streak. This means that when selenite is scratched against a surface or powdered, it leaves a white mark. The streak color is an important property in mineral identification, as it can help distinguish selenite from other minerals with similar appearances.
How is selenite formed?
Selenite is formed through the evaporation of water with high concentrations of calcium and sulfate ions. Over time, these ions combine and crystallize to form selenite structures, typically in underground caves or as mineral deposits in sedimentary environments. Temperature, pressure, and the presence of other minerals can also influence the formation of selenite.
What is the molecular formula for silver selenite?
The molecular formula for silver selenite is Ag2SeO3.Silver selenite is an inorganic compound which forms crystalline needles.
What is selenite used for?
Selenite is commonly used for its calming and purification properties. It is believed to provide emotional healing, promote clarity of mind, and enhance spiritual awareness. Additionally, selenite is used for cleansing and charging other crystals.
Is selenite a silicate?
Selenite is a sulfate as it's chemical structure is CaSO4•2H2O S O combo is sulfur-oxygen, therefore making it a sulfate
Translucent form of gypsum?
The translucent form of gypsum is called selenite. Selenite is a type of gypsum that is clear or white and often found in crystal form. It is prized for its smooth, shiny appearance and light-transmitting properties.
How long is the longest crystal?
The longest crystal ever recorded is a selenite crystal found in the Cave of the Crystals in Chihuahua, Mexico. This crystal measures about 12 meters (39 feet) in length and is estimated to be around 500,000 years old. These massive selenite crystals were formed in a unique geological environment, resulting in their extraordinary size.
When was the largest selenite crystal found?
It was found in 1807 when the Iraq war was still going on.
How are gypsum and selenite chemically similar?
Gypsum and selenite are chemically similar as they both are forms of calcium sulfate with the same chemical formula (CaSO4·2H2O). They have the same crystal structure but differ in their crystal habits - gypsum typically forms as massive white rocks, whereas selenite forms clear and prismatic crystals.
What is the density of selenite?
The Density (In My Testings) of Selenite is 1.8666666 repeating
What is the streak of selenite?
Selenite, a transparent or translucent form of gypsum, has a white streak. This means that when selenite is scratched against a surface or powdered, it leaves a white mark. The streak color is an important property in mineral identification, as it can help distinguish selenite from other minerals with similar appearances.
Does the selenite rock float?
Selenite is a form of gypsum, a dense mineral that does not float in water. It is heavier than water, so it will sink rather than float.
How is selenite formed?
Selenite is formed through the evaporation of water with high concentrations of calcium and sulfate ions. Over time, these ions combine and crystallize to form selenite structures, typically in underground caves or as mineral deposits in sedimentary environments. Temperature, pressure, and the presence of other minerals can also influence the formation of selenite.
How can I effectively cleanse smoky quartz?
To effectively cleanse smoky quartz, you can use methods like sunlight, moonlight, or a cleansing crystal like selenite. Place the smoky quartz in direct sunlight or moonlight for a few hours, or place it on a selenite charging plate overnight. This will help remove any negative energy and recharge the crystal's energy.
What type of rock is selenite?
selenite is sedimentary. But selenite is really a mineral not a rock. It can be found in any rock type
What does sodium selenite do in feed?
Sodium selenite is an inorganic form of selenium. Selenium is needed in a dog's diet. At the time sodium selenite was approved for use in dog foods, it was not known that it poses a high risk for dogs. Unfortunately, its use has not been stopped, but there are dog foods that do not have sodium selenite added to them. In order to avoid feeding your dogs dog food that contains sodium selenite, read the ingredients on the package. Sodium selenite should not be listed, though if grains are listed the food may contain some levels of sodium selenite that is present in the grains, depending on what soil the gran was grown in.
What is the molecular formula for silver selenite?
The molecular formula for silver selenite is Ag2SeO3.Silver selenite is an inorganic compound which forms crystalline needles.
