#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.

#MinCup24 R2M4: #Dioptase versus #Vivianite

Dioptase is rare and has glorious emerald to teal-green vitreous and translucent crystals. Vivianite can grow on decaying wood, bones and other organic material, much to gothic delight.

If this match feels familiar, we saw this same battle in Round 2 Match 3 of Mineral Cup 2023. But every year are new voters with new motivations! Which will you choose this year?
