Sapphires are also known for their durability. They have a rating of 9 on the Mohs scale of mineral hardness, making them ideal for everyday wear in jewellery. They are also resistant to scratches and other types of damage, which is why they have been a favourite choice for royal families and other people of wealth throughout history. The most prized sapphires come from the Mogok Valley in Myanmar, where they are known for their exceptional quality and deep blue colour. But sapphires can also be found in other locations around the world, including Sri Lanka, Madagascar and even Montana in the United States.
