Black Agate is a type of quartz mineral that is often used in jewelry and decorative items due to its attractive black color and bands of white. While it is a semiprecious stone, it may not be the best choice for exterior applications in very dusty climates. Agate is a relatively soft stone, measuring around 6 to 7 on the Mohs scale of hardness. This means it can be easily scratched or damaged by abrasive particles in dusty environments. Over time, the surface of the stone may become dull or lose its polish due to the constant abrasion from dust particles. Additionally, agate is not known for its high resistance to weathering or extreme temperatures. Exposure to the elements in very dusty climates, combined with the abrasive nature of the dust, may accelerate the weathering process and potentially lead to the deterioration of the stone. If you are considering using a semiprecious stone for exterior applications in dusty climates, it is generally recommended to choose a more durable and hard stone, such as granite or basalt, which can better withstand the harsh conditions and maintain their appearance for a longer period.
