Colombian light and emeralds

Light plays a crucial role in the perception of emerald color. The quality, intensity and type of light can highlight different shades and shades of green. This phenomenon is due to how emeralds refract and disperse light, which affects their appearance and visual appeal.

• Avoid noon: In the central hours of the day, sunlight is more intense and direct, which can create dazzle and make it difficult to appreciate the color.

How does light affect the color of emeralds?

The way the light affects the color of the emeralds is due to several factors:

1. Refraction: Emeralds have a high refractive index, meaning the light is diverted when entering the stone, creating a set of lights that highlights its color.
2. Sperm: The way light is separated in different colors as they pass through the emerald can influence visible nuances, adding depth to their green color.
3. Light quality: Natural light, especially diffuse light, highlights the purity and saturation of color. Artificial light, on the other hand, can alter perception, making greens look more off or less vibrant.
4. View angle : The position from which the emerald is observed also affects how its color is perceived. A change in the angle can highlight different nuances and shades.
5. Environmental conditions: The presence of clouds, fog or the time of day can modify the quality of light, affecting what emerald looks like. Atmospheric conditions can add an effect of softness or warmth that highlights its beauty.
