#MinCup24 R2M8: #Charoite versus #Topaz
Chaorite is an intensely purple mineral with a fibrous, swirly pattern that’s been compared to Van Gogh’s Starry Night. It forms from contact metamorphism in Siberia.
Topaz is a hard, many-hued gemstone that crystallizes along the fractures in igneous rock, and is mined all over the world. It is pleochroic; i.e. it can appear different colors from different angles.
Time to choose your mineral!
