Emerald is a precious gemstone and a variety of the mineral beryl (Be₃Al₂(SiO₃)₆). It is known for its rich green color, which is caused by trace amounts of chromium and sometimes vanadium. Here are some key facts about emeralds:
Characteristics of Emerald:
- Color:
- Emeralds are famous for their vibrant green color, ranging from light to deep green. The most valuable emeralds have a pure, intense green hue.
- Hardness:
- On the Mohs scale of mineral hardness, emeralds rank 7.5 to 8, making them relatively durable but still prone to scratches and cracks.
- Clarity:
- Emeralds often have inclusions (internal flaws) called “jardin” (French for garden), which are considered part of their character. Unlike diamonds, flawless emeralds are extremely rare.
- Cut:
- Emeralds are often cut into a rectangular shape called the “emerald cut” to enhance their color and protect them from damage.
