Labradorite is a fascinating gemstone known for its unique iridescence and play of colors.
Color: Labradorite is typically gray, gray-green, or black in its base color, but what makes it stand out is its vibrant play of colors known as labradorescence. This optical effect can include hues of blue, green, yellow, orange, and even flashes of purple or pink. The colors often appear to change as the gemstone is viewed from different angles.
Labradorescence: The distinctive play of colors in labradorite is caused by the interference of light within the layers of the stone. This phenomenon is a result of the scattering of light between twinning planes in the crystal structure.
Transparency: Labradorite is usually translucent to opaque. The intensity of labradorescence can vary, with high-quality specimens exhibiting a strong and vibrant play of colors.
Luster: Labradorite has a pearly to vitreous luster, contributing to its overall attractiveness. The play of colors adds a captivating and mystical quality to the gemstone's appearance.
Cut: Labradorite is often cut into cabochons to best display its labradorescence. The cabochon cut, with a smooth and rounded surface, allows the play of colors to be seen across a broad area. Some lapidaries may also carve intricate shapes to enhance the stone's visual appeal.
Clarity: Labradorite may contain natural inclusions, which are generally accepted as long as they do not significantly impact the gemstone's labradorescence. Inclusions can add character to the stone and are often referred to as "labradorescence veins."
