Abalone shells have long been prized for their beauty and durability. These lustrous shells are used in a variety of ways, from making jewelry to decorating homes. But what exactly are abalone shells? Abalone shells are the outer shell of a type of sea snail known as abalone. These creatures are found in warm waters all over the world and vary in size, color, and shape. The most prized abalone shells are those with a deep, iridescent hue. The colors of abalone shells are created by a layer of nacre, also known as mother-of-pearl. This nacre is formed by tiny calcium carbonate crystals that reflect light, giving the shells their trademark shimmer. In addition to being beautiful, abalone shells are also incredibly strong. In fact, abalone shell has been used throughout history to make armor and weaponry. Today, abalone shell is still prized for its durability and can be found in a variety of products, from jewelry to home decor.
