Why diamond shines at night




















Reflection is the light that hits the diamond and is immediately bounced back up, giving it an instantaneous shine. Only a portion of the light hitting a diamond is reflected; the rest travels through it. As the light moves through the diamond, it is scattered and fractured, creating the sparkle that diamonds are known for. This is the refraction. In essence, diamonds are tiny, complicated prisms; the light enters through the top, and then is angled around the inside of the diamond before being aimed back towards the top and out through the surface.

This creates a rainbow effect dispersion , and adds to the shine. This refraction and dispersion also creates natural light and dark areas in the refracted light, depending on where the light hits along the planes of the diamond. The dark magnifies the intensity of the light. It all comes down to contrast; a diamond without contrast might still shine just as much, but the shine would be significantly less impressive. And at first glance, the Spring Diamond appears to encompass a rather dull region of the sky that is dark and empty to the eye.

However, closer inspection, especially on a dark moonless , clear night, reveals a large, hazy patch of light in the upper-right part of the Diamond. This faint fuzz of stars belongs to the constellation Coma Berenices Berenice's Hair. Averted vision shows this to be a loose swarm of individual stars scattered over an area 5 degrees across. Your clenched fist held at arm's length measures 10 degrees in width, so this open star cluster measures roughly half a fist wide.

Unfortunately, until Thursday March 12 , the moon will sweep right through the Spring Diamond and light up this region of the sky. In the nights that follow, however, the moon will move away to the east, allowing us to see the Diamond and Coma Berenices. Also located within the Diamond is one of the most remarkable areas of the heavens. Sometimes called the Coma-Virgo Cloud of Galaxies and often referred to in older astronomy texts as "The Field of the Nebulae," it's now known colloquially as "The Realm of the Galaxies.

Here, an estimated 1, to 2, galaxies throng together in a huge supercluster. If you own a moderately large reflecting telescope of 6-inch aperture or greater, a sweep of this region will reveal literally dozens of these galaxies, which appear as myriad faint and fuzzy patches of light.

Every one of these dim blobs is in itself a star city, likely containing tens of billions of stars. The Coma-Virgo Supercluster, also known as Abell , dominates our intergalactic neighborhood.

It represents the physical center of our Local Supercluster and influences all the surrounding galaxies and galaxy groups by the gravitational attraction of its enormous mass. And this cluster of galaxies is just the nearest of the large aggregations of galaxies relative to us, somewhere between 40 and 70 million light-years away. This is nothing but because of refraction. It can be explained as follows: We know diamonds are tiny, complicated prisms in which light enters through the top and cut at an angle from inside and from the top through the surface.

This creates a rainbow effect or dispersion and also makes shiny. Depending where the light hits the planes of the diamond, refraction and dispersion occur, creating natural light and some dark areas. Source: www. As, dark magnifies the intensity of light in the similar way as the flame of the candle appears brighter in a dark room than in the lighted room.

Another important feature is the cut of the diamond. If the shape is too deep or too shallow, much of the light will get lost, never bounce back as it suppose to be. The angle for the refraction would let the light slip out of the diamond. So, we can say up to an extent shape of the diamond also determines shine. These cuts only enhance the brilliance of the diamond. Refraction of Light With the cuts in the diamond it is also important to maintain the symmetry, so that the optimum amount of shine remains in it.

The shape of the diamond should remain even from all the ends and with all the facets. If the symmetry is not proper than the amount of light will not refract properly.

On the other hand clarity of the diamond also matters which affects the shining property of the diamond. Blemishes on the surface of the diamond limit the amount of light that can enter the diamond.

Inclusions prevent the light from moving freely within the gem. If the imperfections will be less than diamond will be more brilliant or vice versa.
