Gem characteristics
- They are rare and precious minerals
- They are used for jewelry and other valuables
- They have unique optical properties
Conclusion
In conclusion, minerals, rocks and gems are solid natural elements that differ in their chemical composition, internal structure and physical and optical properties. It is important to know these different characteristics to be able to identify and value them appropriately in different contexts.
