Description
Gemstones are precious or semi-precious minerals that are cut and polished for use in jewelry or decorative purposes. There are a wide variety of gemstones, each with unique properties and characteristics. Some of the most well-known gemstones include diamonds, emeralds, rubies, sapphires, and pearls. Gemstones are classified based on their physical and chemical properties, such as their hardness, luster, color, and transparency. Hardness is measured on the Mohs scale, which ranges from 1 (softest) to 10 (hardest). Some gemstones, such as diamonds, are formed deep within the Earth’s mantle, while others, like pearls, are formed by living organisms. In addition to their use in jewelry, gemstones have also been used throughout history for medicinal and spiritual purposes. Overall, gemstones have captivated people’s attention for centuries, and continue to hold an important place in both science and culture.
