Caves and cliffs idea: Turqoise ore

minecraft needs new gems and minerals, especially in this cave update.

I suggest adding turquoise, a turquoise gem with gold spots and punctuations.

It would be used as a decorative block, the diamond would be replaced in the creation of the enchantment tables (the corners of this would be turquoise), and with it the tridents would be enchanted.

If new civilizations were added in the future, this gem would be a new currency.

If not, it can be used as a bargaining chip with the illusioner.
