Azurite is a basic copper carbonate named after its deep blue colors. the name Azure is derived from the Persian word lazhward which means blue.
Jeweller Magazine mentioned an American legend that claims Azurite is a powerful healing stone, but it is toxic due to its high concentration of copper.
Ixchel Crystals also noted that it has sulfur in it. Like malachite, azurite is pretty harmful when wet--and the runoff water is toxic. Ixchel Crystals also pointed out that it gives off sulfur when mixed with water.
Also mentioned in this episode is Pseudomalachite and you can learn more about that mineral here.
