In the realm of gemstones, the allure of alexandrite stands out not only for its mesmerizing color-changing properties but also for its remarkable hardness.
As we delve into the fascinating world of this precious gem, we uncover the question on many minds: How hard is an alexandrite stone?
Unveiling the Hardness of Alexandrite
Alexandrite earns its place as a relatively hard gemstone, boasting a hardness of 8.5 on the Mohs scale. This scale, ranging from 1 to 10, measures a mineral’s resistance to scratching and abrasion.
With its impressive score, alexandrite showcases its ability to withstand everyday wear and tear, making it a suitable choice for jewelry enthusiasts.
It’s crucial to recognize, however, that while alexandrite is resilient, it is not impervious to scratches. Harder gems like diamonds and sapphires can still leave their mark on this captivating stone.
Thus, although alexandrite offers durability, a degree of care is warranted to preserve its pristine beauty.
Beyond Hardness: The Toughness of Alexandrite
Beyond hardness, alexandrite exhibits excellent toughness and lacks cleavage.
Toughness refers to a gemstone’s ability to withstand impact without breaking, while cleavage pertains to the tendency of a mineral to break along specific planes.
In the case of alexandrite, its robust toughness means it can endure accidental knocks without succumbing to fractures.
This combination of hardness and toughness makes alexandrite an ideal candidate for various types of jewelry, including rings and bracelets. Its capacity to withstand the rigors of daily wear positions it as a gem that not only delights the eye with its color-changing magic but also stands the test of time.
