Albite
overall review score: 4.2
⭐⭐⭐⭐⭐
score is between 0 and 5
Albite is a common mineral belonging to the plagioclase feldspar group. It is a tectosilicate mineral primarily composed of sodium aluminum silicate, characterized by its colorless or white appearance, though it can also occur in shades of pink, gray, or yellow. Albite typically forms in igneous and metamorphic rocks and is recognized for its high cleavage and glassy luster. It plays an important role in both geological processes and as a collectible mineral specimen.
