If you (or the Earth) heats up #kyanite at low pressure (shallow depths), you get #andalusite! Both are Al2SiO5, but with distinct crystal structures. #MinCup26 #MineralCup

For this round this picture looks like a big rock of #Andalusite in the light!

It's interesting how both #kyanite and #andalusite are neighbours on the phase diagram and look quite different - colour-wise!

Aggregate of blue tabular #Kyanite crystals from Ústup u Olešnice, Czech Republic.

Size 10 x 7 cm

Today, for me it's the index mineral and sibling to #Kyanite: #Andalusite!
