Diamonds 'sparkle' based on the high refractive index of the mineral.
Then, add the cut of the stone and its polish which cause light to be reflected and refracted back to the observer's eye.
Note that a raw, uncut diamond will not demonstrate its high refractive index.
It is the quality of the diamond that makes it sparkle not so much whether the setting is white or yellow gold
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.
Moissonite is the second hardest gem on the planet, Diamond is the hardest. Moissonite has a higher refractive index, meaning it will sparkle a bit more.
The proper cut will reflect the light better so it will sparkle.
The word 'sparkled' is the past participle, past tense of the verb 'to sparkle'; the past participle is also an adjective, for example, a sparkled costume.The word 'sparkle' is also a noun, for example, the sparkle in her eyes.
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.

Aloha: 'a [ah] is like the sparkle of a diamond; but the general word is hulali [hoo-lah-lee]
Its extreme hardness.
uhhh well you sparkle like a diamond in the sunlight, it looks like they put glitter all over someone.
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.
