Blue topaz is a popular gemstone known for its captivating blue hue. It is often used in jewelry, such as rings, necklaces, and earrings. However, many people wonder if blue topaz is durable enough to withstand everyday wear and tear. This article will explore the hardness of blue topaz and answer the question: does blue topaz scratch?
The Mohs Scale of Hardness
The Mohs scale of hardness is a measure of a mineral’s resistance to scratching. It ranges from 1 (talc, the softest mineral) to 10 (diamond, the hardest mineral). Minerals with a higher Mohs hardness are more resistant to scratching than those with a lower Mohs hardness.
Hardness of Blue Topaz
Blue topaz has a Mohs hardness of 8. This means that it is harder than most common materials, such as glass (Mohs hardness of 5.5), steel (Mohs hardness of 6.5), and quartz (Mohs hardness of 7). However, blue topaz is softer than diamond (Mohs hardness of 10), sapphire (Mohs hardness of 9), and ruby (Mohs hardness of 9).
