IMPORTANT INFORMATION ABOUT COLOR

Tanzanite is highly appreciated for its extraordinary pleochroic effect, which allows the gemstone to display different shades of blue, violet, indigo, and purple depending on:

• Viewing angle
• Natural daylight
• Indoor lighting conditions
• LED, fluorescent, or halogen illumination
• Camera settings and photographic equipment
• Screen calibration and display technology
• Individual color perception

The photographs and video associated with this listing have been produced using professional lighting equipment designed to showcase the gemstone's brilliance, transparency, and color potential.

Please note that every monitor, smartphone, tablet, and display reproduces colors differently. As a result, slight differences in hue, saturation, brightness, and color intensity should be expected when viewing the gemstone in person.

Tanzanite is particularly responsive to changes in lighting and may reveal different shades throughout the day. This natural behavior is one of the most fascinating characteristics of this gemstone and should not be considered a defect.
