A precious stone, also known as a gemstone, is a rare, naturally occurring mineral or rock that is valued for its beauty, durability, and rarity. Precious stones are typically cut and polished to enhance their natural beauty and may be used for decorative purposes in jewelry or other forms of adornment. Some of the most well-known precious stones include diamonds, rubies, sapphires, emeralds, and pearls, all of which have been highly valued throughout history for their beauty and symbolism. The value of a precious stone is often determined by factors such as its size, color, clarity, and cut, as well as its rarity and historical significance.
