Tanzanite’s defining characteristic is its trichroism, displaying three different hues dependent on viewing angle and lighting conditions. Typically, it exhibits shades of blue, violet, and purple. These colors can range from a deep, saturated blue, comparable to some sapphires, to lighter, more pastel variations of violet. The precise shade is influenced by factors like the stone’s inherent composition and any heat treatment applied to enhance its color.
The appeal of this gem lies in its unique and varied color palette. The presence of multiple colors within a single stone offers a captivating visual experience. Furthermore, the relatively recent discovery of this gemstone, coupled with its limited source in Tanzania, contributes to its desirability and perceived rarity. The color, therefore, is a significant factor in its value and allure to collectors and jewelry enthusiasts alike.
