polarisabele

Polarisabele is a rare and distinctive mineral species discovered in 2019. It is named after the North Star, Polaris, and the Greek word "abeles," meaning "white," reflecting its color. Polarisabele is a calcium aluminum borate hydroxide with the chemical formula Ca2Al3(OH)12(BO3)3. It crystallizes in the trigonal system and typically forms as white, prismatic crystals. The mineral is known for its unique crystal structure and its occurrence in rare, high-temperature hydrothermal veins. Polarisabele has a Mohs hardness of 4.5 and a specific gravity of approximately 2.7. It is typically found in association with other borate minerals such as datolite and ulexite. Due to its rarity and distinctive properties, polarisabele is of interest to mineral collectors and researchers studying the geochemistry of borate minerals. Its discovery has contributed to the ongoing study of mineral diversity and the processes that form these unique geological formations.
