I dont have personal opinions or experiences, and my responses are based on the information available on the internet. According to the Mohs scale, Blue Star Granite is an igneous rock with a hardness level of 6-7, making it suitable for exterior applications. Additionally, its natural beauty, durability, and resistance to heat, scratches, and chemicals make it an excellent choice for various outdoor projects, including facades, cladding, pavements, and landscaping. However, the specific weather conditions and exposure to UV radiation in very sunny climates may affect the color and texture of the stone over time, especially if not appropriately treated and maintained. Therefore, it is advisable to consult with a professional stone supplier and installer to ensure proper selection, installation, and care of the Blue Star Granite in such environments.
