Gemstones are naturally occurring minerals or organic materials that are cut and polished for use in jewelry and other adornments. Their appeal lies in their beauty, rarity, and durability. The beauty of a gemstone is often attributed to its color, clarity, cut, and carat weight. Color is the most significant factor for many gemstones, with specific hues and saturations being highly prized. Clarity refers to the presence or absence of internal inclusions or external blemishes. The cut of a gemstone is crucial for maximizing its brilliance and fire, while carat weight determines its size.

Gemstones are broadly categorized into precious and semi-precious stones. Historically, the precious stones were diamond, ruby, sapphire, and emerald. All other gemstones were considered semi-precious. This distinction is now largely considered outdated by gemologists, as many semi-precious stones can be rarer and more valuable than some precious ones. Some well-known semi-precious gemstones include amethyst, aquamarine, garnet, peridot, topaz, and tourmaline. Organic gemstones, such as pearls, amber, and coral, are formed from living organisms rather than minerals.

The formation of gemstones occurs through various geological processes over millions of years. These processes can involve intense heat and pressure deep within the Earth's crust, or the slow deposition of minerals from hydrothermal solutions. The unique combination of chemical composition, crystal structure, and environmental conditions dictates the type of gemstone that forms. Gemstones are mined from deposits found across the globe, with different regions being known for specific types of stones. Their value is influenced by factors such as supply and demand, historical significance, and the current trends in the jewelry market.
