Spinel is a beautiful gemstone that comes in a range of colors, including red, blue, pink, purple, and black. It is often mistaken for other gemstones like ruby and sapphire because of its similar appearance, but it has its own unique characteristics.
One of the most notable things about spinel is its exceptional hardness, which makes it a durable and long-lasting gemstone. It has a Mohs hardness rating of 8, which means it is just below diamond in terms of hardness.
