A diamond can be either, depending on the natural colour of the stone.
Some diamonds are fluorescent. This means that light enters the stone and the wave length is converted to a longer light wave. Not all diamonds are fluorescent. No diamond will 'glow in the dark' without first being exposed to a light source.
No, real diamonds do not glow in the dark on their own. They do not possess any inherent luminescence properties. However, under UV light, some diamonds may exhibit fluorescence and emit a subtle glow.
No, i don't think so because you have to know that diamonds were first made from carbon.

Black diamonds are known for their unique color and light-absorbing properties, which give them a distinctive appearance compared to traditional white diamonds. While black diamonds may not reflect light in the same way as white diamonds, they can still exhibit a beautiful luster and sparkle due to their polished surfaces and faceting. The dark color of black diamonds may create a different kind of brilliance that is more subtle and mysterious.
Violet diamonds are usually called diamonds. There may be descriptor words to modify the noun, and can include "...Violetish-Blue, Bluish-Violet, [and] Violet..." and then the intensity of the colour is described in one of nine ways, including " ...Faint, Very Light, Light, Fancy Light, Fancy, Fancy Dark, Fancy Intense, Fancy Deep, Fancy Vivid..."
No, raw black diamonds are not transparent. They appear black due to numerous inclusions and impurities that scatter light, giving them their dark color. Transparency is associated with white or colorless diamonds.
Yes. Reflection and refraction are qualities of faceted diamonds.
In a cave with zero light, you would not be able to see any reflection from a diamond since there is no light source. However, if there is moonlight, starlight, ambient light from any source, your diamond will sparkle.
Light.
A purple diamond is probably a pink-purple or red-purple in colour. A yellow diamond may be called a 'canary'. All coloured diamonds are graded by colour and by these nine descriptors, according to Wikipedia: " Faint, Very Light, Light, Fancy Light, Fancy, Fancy Dark, Fancy Intense, Fancy Deep, Fancy Vivid."
Diamonds are not reflective like mirrors: diamonds refract light and split the beams or light sources into colours. This characteristic of the diamond material is what gives a diamond its 'fire'.
