In absolute darkness, for example, inside a closed cave, a diamond would not be visible.
A diamond depends on a light source in order to reflect and refract light. Any ambient light, from the moon, or a streetlight or candlelight will be picked up by a diamond and cause it to shine.
They have high refractive index and total internal reflection in the multiple facet structure that reflects light to shine at night.

In complete darkness, devoid of any light -- deep within a cave, for example -- no diamond will 'shine'. Every diamond, however, will reflect and refract ambient light, even if it is simply moonlight or starlight.

If the diamond shines too much is of a frosty color,you may consider it fake.
because of total internal reflection
