Pearl is a lustrous and precious gemstone that has captivated human fascination for centuries. It is formed within the soft tissue of certain molluscs, primarily oysters and mussels, as a result of a protective response to an irritant such as a grain of sand. The mollusc secretes layers of nacre, a crystalline substance composed of calcium carbonate, which gradually builds up to form a smooth, round pearl.

Pearls are renowned for their natural beauty and iridescent lustre, which gives them a captivating glow. They come in various colours, including white, cream, silver, pink, and even rare hues like black and gold. Each pearl possesses a unique set of characteristics, such as size, shape, colour, and surface quality, making it a highly individual and sought-after gem.
