Precious jewels are highly valued and sought after gems that are typically used for decorative or ornamental purposes. These gems are highly desirable due to their rarity, beauty, and durability, and are often used in jewelry or other high-end accessories. Examples of precious jewels include diamonds, emeralds, rubies, sapphires, and pearls.
Diamonds are the most well-known and highly prized of all precious jewels, prized for their brilliance and sparkle. They are composed of carbon, and their unique crystal structure makes them the hardest natural substance on earth.
