The answer for their brightness is the refractive index of them. the light which inters the diamond does not come out because of total internal reflection into air whose refractive index is close to vacuum's i.e 1. hence diamonds shine a lot. It has a lot to do with the cut. A good cut allows it to reflect light.
It is because they reflect certain wavelengths (colors) of light more readily than others. White light contains all wavelengths of light. You can see this by passing the light through a prism or by observing a rainbow. Now, if you have an object such as an orange and shine white light on it. The red and yellow will be reflected and the other colors will be absorbed. Thus, we see an orange object. Now, if you shined pure blue light on the orange it would look black, because there would be no red or yellow to reflect.

Elements with luster would be classified as metals. Metals will also have the properties of malleability and ductility. Luster: the shine of a metal object Malleability: the flexibility of a metal Ductility: the ability of a metal to be pulled into thin wires
When cut and polished , it has a high refractive index , and reflects any available light.
The material's Luster (lustrous would mean it reflects light) (dull is the opposite)
reflectAnother AnswerCut and polished diamonds both shine and reflect under available light.
Planets shine because they reflect light from the sun.
The planets do not emit light, they reflect sunlight.
Because the light can shine through it?
No planets reflect light from their host star (sun)
Moons and comets appear to shine because of the light they reflect. Stars produce their own light.
Diamonds do not shine but reflect the light from which is pointing at it, to make it seem like it is shining.
The moon and planets reflect sunlight, they do not produce light.
the light will reflect and will split in 7 colors.
The fluorescence in a mineral is where it will shine or reflect under a ultraviolet light.
Diamonds have highly reflective surfaces with many facets. This causes them to shine and reflect light very easily which causes them to shine.
