Given a light source and movement, a diamond will sparkle in air or under water.

I would expect the effect to be greater in air than in water though, because the density difference between diamond and surroundings are that much greater.
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.
Refraction and reflection both contribute to the sparkle you see in a diamond. Diamonds naturally have a high refractive index, meaning they are 'light friendly'. This property makes diamonds sparkle under any available light: moonlight, starlight, flashlight, firelight and so forth. A well-cut diamond also has reflective qualities: the diamond cutter designed the cut so that light taken in from any facet reflects on other facets and back into the eye of the beholder.
No. Diamonds reflect and refract light. Without a light source, a diamond cannot be seen.No, a diamond is not a source of light. A cut diamond appears to sparkle because it is very good at scattering light that strikes it.
Diamonds sparkle when light enters them. Depending on the type of cut and the workmanship of the cutter a diamond can give off more or less sparkle. The diamond cutter cuts exact angles into the stone which makes the diamond sparkle. Diamonds as we know them sparkle because of the facets that are cut into them whilst shaping them. Natural diamonds that haven't yet been mined don't sparkle as such. For example, a Round Brilliant Cut diamond is just the simple round diamond shape we see all the time, and it contains between 56-57 facets; when any light enters the diamond, it is reflected off 56-57 differently angled surfaces on the diamond, not just one. They can be cut further than the generic amount to sparkle even more; a lot of jewellers do special collections of diamonds where the Round Brilliant cut has 73 facets instead of 56. Diamonds have a high refractive index--which means they can really bend light rays. So light rays that shine into them will stay inside the diamond longer than they would inside glass, plastic, or any other material with a lower refractive index. And diamonds are cut to maximize this light capturing effect. All those sides and angles are carefully designed to keep incoming rays inside a long time--by making them bounce off as many walls as possible. Several physical elements are involved, including diffraction and refraction: According to Wikipedia, the definition of diffraction is: "Diffraction refers to various phenomena which occur when a wave encounters an obstacle." Diamonds sparkle based on refraction, defined by Wikipedia as: "Refraction is the change in direction of a wave due to a change in its speed." In sum, facets and their angles in and on the gem coupled with the natural attributes of diamonond mineral, cause light to 'bounce' within the diamond, and exit into your eyes, causing 'sparkle'.
noAnother AnswerIn polar climates or very cold locations, it's possible to throw water into the air and have it fall to earth as 'diamond dust', because the smallest droplets are frozen in the air. These are ice crystals, and not related at all to the mineral that composes a diamond.
A black diamond won't sparkle like a white diamond, but a very special black diamond, the Amsterdam Black Diamond is apparently a visually stunning stone. Read more, below.
The diamond sparkled in the light. OR "Did it sparkle?" asked John.
Diamonds sparkle according to the refractive angles cut into the stone. A single-cut diamond has 17 facets; common round cuts today have more than 50 facets. There's no question that a single-cut diamond will sparkle, but it might not sparkle as much as a diamond of the same weight with more facets cut into it.

Aloha: 'a [ah] is like the sparkle of a diamond; but the general word is hulali [hoo-lah-lee]
It is the quality of the diamond that makes it sparkle not so much whether the setting is white or yellow gold
Water simply adds another element of refraction to a diamond. The stone's sparkle is based on the excellence of its cut and the source of light to which it is exposed.
uhhh well you sparkle like a diamond in the sunlight, it looks like they put glitter all over someone.

Air
No. Diamond stones are worked by diamond cutters, who carve and polish facets on the diamond stones, to make the stones sparkle. Facets are flat surfaces on stones that reflect light.
carbon dioxide is added to it which form bubbles to make it sparkle
