What To Know
- To assess the hardness of a gemstone, gemologists utilize the Mohs Scale of Hardness, a standardized measure developed by renowned mineralogist Friedrich Mohs in 1812.
- This makes it a practical option for those seeking a gemstone that can be worn frequently without compromising its beauty or integrity.
- Its position on the Mohs Scale of Hardness, coupled with its captivating blue-violet hues, makes it a sought-after choice for jewelry enthusiasts and collectors alike.
Tanzanite, with its captivating blue-violet hues, has captivated jewelry enthusiasts and collectors worldwide. Beyond its mesmerizing beauty, this gemstone possesses remarkable strength and durability, making it an ideal choice for everyday wear. In this comprehensive guide, we delve into the question “Is tanzanite hard?” and explore the factors that contribute to its exceptional resilience.
Understanding the Mohs Scale of Hardness
To assess the hardness of a gemstone, gemologists utilize the Mohs Scale of Hardness, a standardized measure developed by renowned mineralogist Friedrich Mohs in 1812. This scale ranks minerals based on their resistance to scratching, with talc being the softest at 1 and diamond being the hardest at 10.
Tanzanite’s Position on the Mohs Scale
Tanzanite falls between 6.5 and 7 on the Mohs Scale of Hardness, indicating that it is a relatively hard gemstone. This places it above many commonly used gemstones, such as emerald (7.5-8), topaz (8), and aquamarine (7.5-8). However, it is essential to note that tanzanite is not as hard as diamonds (10), rubies (9), or sapphires (9).
Factors Contributing to Tanzanite’s Hardness
Several factors contribute to tanzanite’s notable hardness:
- Chemical Composition: Tanzanite’s chemical composition, consisting primarily of calcium, aluminum, and silicon, provides a solid foundation for its structure. The strong bonds between these elements result in a gemstone that can withstand external forces and resist scratching.
- Crystalline Structure: Tanzanite’s crystalline structure, characterized by tightly packed atoms arranged in a specific pattern, further enhances its hardness. This structure creates a strong and stable framework that makes it difficult for the gemstone to be scratched or damaged.
- Heat Treatment: Tanzanite undergoes heat treatment to enhance its color and clarity. This process involves heating the gemstone to high temperatures, which can strengthen its structure and improve its overall durability.
Implications of Tanzanite’s Hardness for Jewelry
Tanzanite’s hardness makes it a suitable choice for various jewelry applications, including rings, earrings, necklaces, and bracelets. Its durability ensures that it can withstand the rigors of everyday wear without easily scratching or chipping. This makes it a practical option for those seeking a gemstone that can be worn frequently without compromising its beauty or integrity.
Caring for Tanzanite Jewelry
While tanzanite is a hard gemstone, proper care is essential to maintain its pristine condition and prevent damage:
- Avoid Harsh Chemicals: Exposure to harsh chemicals, such as chlorine or bleach, can harm tanzanite. Remove your tanzanite jewelry before engaging in activities that involve contact with these chemicals.
- Store Tanzanite Jewelry Properly: Store tanzanite jewelry in a soft, lined box or pouch to prevent scratching. Keep it separate from other gemstones to avoid potential damage from accidental contact.
- Regular Cleaning: Clean your tanzanite jewelry regularly using a mild detergent and warm water. Avoid ultrasonic cleaners, as they can damage the gemstone.
Additional Factors to Consider When Assessing Tanzanite’s Hardness
In addition to the Mohs Scale of Hardness, other factors can influence the perceived hardness of tanzanite:
- Cut and Shape: The cut and shape of a tanzanite gemstone can affect its apparent hardness. Stones with sharp edges or points may appear more susceptible to chipping or scratching.
- Clarity: Inclusions or fractures within a tanzanite gemstone can weaken its structure and make it more prone to damage.
- Color: The color of tanzanite can also influence its hardness. Darker tanzanites tend to be harder than lighter ones due to the presence of additional trace elements.
Takeaways: Tanzanite’s Enduring Beauty and Strength
Tanzanite stands as a testament to nature’s ability to create gemstones of extraordinary beauty and resilience. Its position on the Mohs Scale of Hardness, coupled with its captivating blue-violet hues, makes it a sought-after choice for jewelry enthusiasts and collectors alike. With proper care and maintenance, tanzanite jewelry can be enjoyed for generations, adding a touch of elegance and sophistication to any outfit.
