A gemstone, often referred to as a gem, jewel, or precious stone, is a piece of mineral crystal that has been cut and polished for use in jewelry or other decorative applications. Some gemstones can also be organic materials, such as pearls and amber. They are highly valued for their beauty, durability, and rarity.
Characteristics of Gemstones
- Beauty: The visual appeal of a gemstone can stem from its color, clarity, and luster. The beauty may be enhanced by the way light interacts with the stone, exhibiting phenomena like iridescence or asterism.
- Durability: Gemstones must withstand wear and tear; thus, hardness is a key factor. The Mohs scale measures hardness, with diamonds being the hardest at a rating of 10.
- Rarity: The scarcity of a gemstone contributes significantly to its value. Precious gemstones include diamonds, rubies, sapphires, and emeralds, while all others are classified as semi-precious.

- Natural Gemstones: Formed through natural geological processes over millions of years.
- Synthetic Gemstones: Created in laboratories to mimic the properties of natural stones.
- Aggregate Gems: Formed alongside other minerals.
