#MinCup24 R4M2: #Dioptase versus #Kyanite

Dioptase, the desert emerald, forms in alteration zones of deserts. It is so sparkly that its name alludes to the visibility of internal cleavage planes. Blue blades of Kyanite are a classic mineral found in rock shops, introductory geology classrooms, eroded mountains, and geological research laboratories.
