Question
Which one of the following gemstones contains beryllium metal?
The correct answer is
Emerald
Gemstone Beryllium Identification
The question asks to identify the gemstone containing the metal beryllium. Let's analyze the options:
Gemstone Composition Analysis
- Emerald: Emeralds are a variety of the mineral beryl. The chemical formula for beryl is
Be₃Al₂(SiO₃)₆$. This formula clearly shows the presence of beryllium (Be). - Topaz: Topaz is a silicate mineral containing aluminum and fluorine, typically
Al₂SiO₄(F,OH)₂$. It does not contain beryllium. - Ruby: Ruby is a gemstone variety of the mineral corundum (
Al₂O₃$). It does not contain beryllium. - Blue Sapphire: Blue sapphire is also a variety of the mineral corundum (
Al₂O₃$). It does not contain beryllium.
Conclusion
Based on the chemical compositions, Emerald is the gemstone that contains beryllium metal as a key component of the beryl mineral structure.
