Introduction:
Tanzanite, a captivating gemstone renowned for its mesmerizing blue hues, holds a special place among jewelry enthusiasts. However, with the prevalence of imitations in the market, it’s essential to know how to check tanzanite to ensure you’re getting a genuine gemstone. This comprehensive guide will equip you with the knowledge to confidently assess the authenticity of tanzanite.
1. Color:
Tanzanite’s distinct blue color is one of its most recognizable characteristics. Genuine tanzanite typically exhibits a deep, saturated blue with hints of violet or purple. Be wary of stones with an excessively vivid blue color, as they may have undergone artificial treatments.
2. Clarity:
Tanzanite is often naturally included, meaning it may contain small imperfections or inclusions. These inclusions can add character to the gemstone, but excessive clarity may indicate synthetic or treated stones.
3. Cut:
Tanzanite is commonly cut into various shapes, including round, oval, and cushion. The cut of the stone can impact its brilliance and fire. Well-cut tanzanite will showcase its color and clarity to the fullest.
4. Pleochroism:
Pleochroism is a unique optical property of tanzanite that causes it to display different colors when viewed from different angles. Genuine tanzanite will exhibit a distinct change in color, typically from blue to violet or purple, as you rotate it.
5. Fluorescence:
Tanzanite often exhibits fluorescence under ultraviolet light. When exposed to UV light, genuine tanzanite will typically fluoresce a strong blue or purple color. This property can be used to distinguish tanzanite from other blue gemstones.
6. Specific Gravity:
Specific gravity is a measure of a gemstone’s density. Tanzanite has a specific gravity of around 3.3 to 3.5. If a stone’s specific gravity falls outside this range, it may be an imitation or treated gemstone.
7. Gemological Certification:
Obtaining a gemological certification from a reputable laboratory is one of the most reliable ways to ensure the authenticity of tanzanite. Gemological laboratories, such as the Gemological Institute of America (GIA) or the American Gem Society (AGS), provide detailed reports that verify the gemstone’s identity, quality, and origin.
8. Reputable Sources:
Purchasing tanzanite from reputable sources is crucial. Look for established jewelers with a history of integrity and a commitment to providing genuine gemstones. Avoid buying tanzanite from unknown or questionable sources, as the risk of obtaining a fake or treated stone is higher.
The Bottom Line:
By following these guidelines, you can increase your chances of acquiring genuine tanzanite and avoid falling victim to imitations or treated gemstones. Remember, the authenticity of a gemstone is paramount, as it directly affects its value and desirability. Make informed decisions and seek the guidance of reputable jewelers and gemological laboratories to ensure you’re getting the real deal when purchasing tanzanite.

1. How can I tell if tanzanite is real or fake?
Genuine tanzanite typically exhibits a deep, saturated blue color with hints of violet or purple, while fake stones may have an excessively vivid blue color. Additionally, natural inclusions, pleochroism, fluorescence under UV light, and a specific gravity within the range of 3.3 to 3.5 are all indicators of genuine tanzanite.
2. Is tanzanite a valuable gemstone?
Tanzanite is a relatively rare gemstone, and its value is determined by various factors such as color, clarity, cut, and carat weight. High-quality tanzanite with intense blue color and minimal inclusions can command a significant value.
3. How can I care for tanzanite jewelry?
To maintain the beauty and longevity of your tanzanite jewelry, it’s essential to clean it regularly using mild soap and warm water.
