Appreciate your kind words Pierre!
The word ‘Morralla’ describes the opaque low-grade rough material mainly used for cheap jewelry and handicrafts.
When mining for emeralds, the presence of morralla is sometimes a good indicator of crystallized emeralds in the vicinity.

PS: Should be 'Morralla' and not 'Moralla' as initially written. Thanks for pointing this out Jordi!
