In their natural state, diamonds look like transparent crystals with a shiny, reflective surface. They are typically colorless or have a slight yellow or brown tint.
Diamonds that are made in a laboratory are known as lab-grown diamonds . These diamonds are considered minerals since they are optically and chemically similar to mined diamonds, formed by the same mineral known as carbon. The only difference between mined and lab-grown diamonds is where carbon is crystallized- the earth's crust or the lab. CVD diamonds look exactly like mined diamonds and sparkle like natural diamonds, which is why they are known as minerals. There is no chemical or visual difference between lab-created and mined diamonds.
The difference is big: synthetic diamonds are real diamonds and repeat all properties of natural diamonds, simulants are just trying to copy the brightness of the valuable gemstone. Synthetic's price is usually much higher than simulants. For more information on simulants and real diamonds follow the attached link.
No diamond is fake; but there are fake diamonds. Because natural diamonds are expensive and engaging to the human eye, many people want to own and wear diamonds, so a fake diamond can be substituted in the place of a real stone.
One way to separate clear diamonds from clear plastic imitations is by examining their hardness. Diamonds are one of the hardest natural materials, so they can scratch glass or plastic imitations. Another way is to check for the gem's refractive index, as diamonds have a higher refractive index compared to plastics. Lastly, you can also use a loupe or magnifier to look for natural inclusions or imperfections that indicate a real diamond.
Diamond are desirable for its look on how it shines in the light and for how few and little their are in the world. People like to have the items like designer clothing, 14 carrot jewelry, and special made items. Diamonds are in that category. BUT diamonds aren't of a need like coal or gasoline. Just to look pretty and rich at the same time AND feel on top of the world with MONEY:)
You can review the link, below, to look at images of natural diamonds.
Uncut unshaped diamonds look like shiny black coal
It is a colourless gas.
You can pick up diamonds from the earth at the Crater of Diamonds State Park in Arkansas.
pretty and on growing.

It is a redish brown color.
Black diamonds are diamonds, but they are black, and not transparent. Follow the link, below, to see photos of black diamonds.
Diamonds come out of the ground looking like rough, unpolished crystals. They may appear cloudy, dull, and in various shapes such as octahedral or cubic. The raw diamonds have a rough texture and must be cut and polished to reveal their natural sparkle and beauty.
A fresh surface of plutonium is silvery, metallic.
Faceted, finished brown diamonds are simply diamonds within that colour range. Chocolate diamonds are an intense brown colour.
One answer could be the inexperience of the diamond viewer. Another is that many diamonds are no bigger than a grain of rice, also their color can be missed against the natural color of the ground. The field test for diamond is 'extreme hardness'. As well only about 25% of natural diamonds are of gem-stone quality, so the other 75% of diamonds found will not appear to possess a natural clarity or colour commonly associated with gem-stone quality rocks.
