Gold: A highly valued metal, commonly used in jewelry. It comes in different karats, such as 24K (pure gold), 18K (75% gold mixed with other metals), 14K (58.3% gold), etc.
Silver: Another popular precious metal. Sterling silver, which is 92.5% silver and 7.5% other metals (usually copper), is frequently used in jewelry.
Platinum: A dense, durable, and rare metal. It is often used in high - end jewelry, especially for engagement rings and fine pieces.
Diamonds: Renowned for their hardness, brilliance, and sparkle. They are graded based on the "Four Cs": carat weight, cut, color, and clarity.
Precious Gemstones: This category includes rubies (red corundum), sapphires (blue corundum, although they can come in other colors too), and emeralds.
Semi - precious Gemstones: A vast group that includes amethyst, topaz, turquoise, peridot, and many others.
Pearls: Formed inside mollusks, they can be natural or cultured. Freshwater pearls and saltwater pearls (such as Akoya, South Sea, and Tahitian pearls) are common types.

Disadvantages:
Tarnishing: Sterling silver can tarnish over time when exposed to air, humidity, and certain chemicals, which requires regular cleaning to maintain its shine.
