Does Tanzanite Change Color? This captivating gemstone, renowned for its vibrant hues, is indeed known for its remarkable color-shifting properties. This phenomenon, known as pleochroism, allows tanzanite to display different colors depending on the angle of light and the direction from which it’s viewed. Let’s delve into the fascinating world of tanzanite and explore the secrets behind its captivating color changes.
Understanding Tanzanite’s Color Change
Tanzanite’s color change isn’t a mere trick of the light. It’s a result of its unique crystal structure, which selectively absorbs and transmits different wavelengths of light. This phenomenon, called pleochroism, is what gives tanzanite its mesmerizing ability to shift between shades of blue, violet, and even burgundy. The most prized color is a deep, vibrant blue with a hint of violet, often referred to as “blue-violet tanzanite”.
Different lighting conditions play a crucial role in how tanzanite’s color is perceived. Incandescent light tends to bring out the violet hues, while fluorescent light emphasizes the blue. Natural daylight often showcases a balanced blend of blue and violet, creating a truly captivating display.
Factors Influencing Tanzanite’s Color
Several factors contribute to tanzanite’s color change:
- Crystal Orientation: The way a tanzanite crystal is cut significantly impacts its color. Skilled gem cutters carefully orient the stone to maximize the desired color, often aiming for a vibrant blue-violet.
- Heat Treatment: Most tanzanite on the market undergoes heat treatment to enhance its blue color. This process removes brownish hues and intensifies the blues and violets, resulting in the stunning colors we associate with this gem.
- Clarity: Inclusions within the tanzanite crystal can also affect its color, sometimes causing areas of lighter or darker hues.
“Tanzanite’s beauty lies in its versatility,” says renowned gemologist, Dr. Amelia Stone. “Its ability to shift between different colors gives it a unique charm and makes it a truly captivating gemstone.”
Does Tanzanite Change Color Over Time?
While tanzanite’s color changes depending on the lighting and viewing angle, it doesn’t typically change color over time. However, prolonged exposure to extreme heat or strong sunlight can potentially fade the color, especially in lighter-colored stones. Proper care and storage can help preserve tanzanite’s vibrant hues for generations to come.
How to Care for Tanzanite Jewelry
To maintain tanzanite’s beauty:
- Avoid exposing it to harsh chemicals or extreme temperatures.
- Clean it gently with warm soapy water and a soft brush.
- Store it separately from other jewelry to prevent scratching.
“Protecting your tanzanite jewelry from harsh conditions will ensure its vibrant colors remain captivating for years to come,” advises Dr. Stone.
Identifying Genuine Tanzanite
Due to its popularity and value, tanzanite is sometimes imitated. Knowing how to identify genuine tanzanite can protect you from purchasing counterfeit stones. Look for the characteristic pleochroism, which is a key indicator of genuine tanzanite. Consulting a reputable gemologist is always recommended for accurate identification.
