Pearls are lustrous gemstones formed within the soft tissue of a living shelled mollusk. They are valued for their beauty and rarity and are often used in jewellery such as necklaces, earrings, and bracelets. They come in a variety of colours, including white, cream, black, and pink, and can be round, oval, or irregular in shape. The most prized is a large white pearl with an incredible metallic sheen. They have been treasured for centuries and are often associated with elegance and luxury. The pearl is one of the only gemstones that cannot be synthetically created in a lab as they are an organic gemstone.
