reiakin
Reiakin is a rare and unique mineral discovered in the late 20th century. It is named after the Reia River in Siberia, Russia, where it was first found. Reiakin is a complex silicate mineral with the chemical formula (Na,K)2Ca2(Si8O20)(OH,F)2. It crystallizes in the monoclinic system and typically forms prismatic crystals or granular masses. Reiakin is usually colorless or white, but it can also be found in shades of yellow, green, or brown due to impurities.
Reiakin is primarily of interest to mineralogists and collectors due to its rarity and unique crystal structure.
Reiakin's discovery was a significant event in the field of mineralogy, as it represented a new addition
