Question 1: Which is the hardest gemstone on the Mohs scale?
- Citrine
- Diamond
- Opal
Correct Answer: Diamond
Fact: The hardest gemstone on the Mohs scale is diamond, which has a perfect score of 10. This means it is the most scratch-resistant natural material on Earth. Diamonds are often used in jewelry and cutting tools because of their extreme hardness. No other gemstone can scratch a diamond, but it can scratch all others.
Question 2: Which ranks higher on the Mohs scale: a Herkimer diamond or a ruby?
- They’re the same hardness
- Herkimer diamond
- Ruby
Correct Answer: Ruby
Fact: A ruby ranks higher on the Mohs scale than a Herkimer diamond. Rubies have a hardness of 9, while Herkimer diamonds (a type of quartz) have a hardness of 7. This means rubies are much harder and more scratch-resistant than Herkimer diamonds.
Question 3: What would a jeweler use the Mohs scale for?
- To see if a gemstone fades in sunlight
- To see how durable a gem is for daily wear
- To see a gemstone’s weight
Correct Answer: To see how durable a gem is for daily wear
Fact: A jeweler uses the Mohs scale to check how hard a gemstone or metal is. It helps them know if a stone can get scratched easily or if it can scratch other materials. This is important for choosing the right settings and ensuring the jewelry stays durable over time.
