Calcite Orange is a semiprecious stone that is typically used for interior applications such as countertops, tabletops, and decorative items. However, it may not be suitable for exterior applications in very dusty climates due to its properties.

Calcite is a relatively soft and porous stone, which means it is more susceptible to scratches, stains, and weathering compared to harder stones like granite or quartzite. In a dusty climate, fine dust particles can settle on the stones surface and eventually cause it to lose its shine and aesthetics. Additionally, calcite is sensitive to acidic substances, so exposure to acid rain or other acidic elements in the environment can potentially damage the stone.

If you require a stone for an exterior application in a very dusty climate, it is recommended to choose a more durable and less porous stone that can withstand harsh weather conditions and resist staining. Granite, quartzite, or certain types of porcelain may be more suitable options for such applications. It is always best to consult with a stone supplier or a professional in the field to determine the most appropriate stone for your specific needs and climate conditions.
