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.
selenite is sedimentary. But selenite is really a mineral not a rock. It can be found in any rock type
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.
Selenite is found in countries with significant deposits, such as Mexico, Russia, the United States, Australia, and Greece. It is often found in caves, salt flats, and other areas with high levels of mineral content.
The worldâ??s largest natural rock crystals come from two natural cave cavities found in the Naica Mine, in the state of Chihuahua, south of Chihuahua City, in Northern Mexico. The giant cave has Selenite that reach eleven meters in length.
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.
The largest crystal in the world is called the Nacia it is found in Mexico.
The gypsum crystals of the "Cueva de los Cristales" in the Naica mine of northern Mexico reach 11 meters in length. The hellish conditions (54°C, 100 percent humidity) will prevent this from becoming a tourist attraction, but they preserve the giant crystals of clear selenite. I bring all this up because the upcoming Geology features this image on its cover, heralding a paper on the origin of the crystals by a Spanish-Mexican research team.

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.
The molecular formula for silver selenite is Ag2SeO3.Silver selenite is an inorganic compound which forms crystalline needles.
