How does a diamond become pink?

Answer 1

If a diamond were made completely of pure carbon and flawless, it would be completely colourless. But since very few things occur naturally with that degree of purity and exactness, most diamonds have some kind of colour.

The colour they develop depends on WHAT is causing the colour. Nitrogen atoms creeping into the structure, for example, make diamonds yellowish... this is the most common impurity. Boron makes diamonds greyish. Hydrogen makes them bluish.

Pink and redness is actually caused not by an impure material but by deformations in the crystal shape, called 'plastic deformation'. This is pretty rare in diamonds overall, but is found most often in Australian diamonds. The Steinmetz Pink is the largest pink diamond known (link 1).

Answer 2

Color & Composition

Diamonds occur in a wide variety of colors: colorless, white, blue, steel (grey), yellow, orange, pink, red, brown, green, and black. Colored diamonds contain certain impurities or structural defects that cause the coloration, while "pure" diamonds are transparent and colorless.

Type 1 diamonds have nitrogen atoms as the main impurity. If they are in clusters they do not affect the diamond's color (Type 1-A). If dispersed throughout the crystal they give the stone a yellow tint (Type 1-B). Typically a natural diamond crystal contains both Type 1-A and Type 1-B material. Synthetic Diamonds containing nitrogen are Type 1-B.

Type 2 diamonds have very few nitrogen impurities. Type IIa diamond can be colored pink, red, or brown due to structural anomalies arising through plastic deformation. Type 2-B is the blue diamond containing scattered boron within the crystal matrix.

Experimentation in the late 18th century showed that diamonds were made of carbon. By igniting a diamond in an oxygen atmosphere, the end product of the combustion was carbonic acid gas (or carbon dioxide). Diamond had previously been shown to burn in experiments conducted in the ancient Roman period although the reason was not understood at the time. Diamonds are carbon crystals that form deep within the Earth under high temperatures and extreme pressures. At surface air pressure (one atmosphere), diamonds are not as stable as graphite, and so the decay of diamond is thermodynamically favorable. ***

Answer 3

The impurity which colors pink diamonds is hydrogen. Many pink diamonds are found in Australia. Some synthetic diamond manufacturers make very good looking pink diamonds....

Answer 4

Colored diamonds contain impurities or structural defects that cause the coloration

i actually have no idea but they are so beautiful

if you go on here im suren there is somwthing that will tell you about it.

happy pink diamonding

Answer 6

Different minerals in the coal before compression can change the color.

Answer 7

Diamond is the hardest natural material known to man and the third-hardest known material after aggregated diamond nanorods and ultrahard fullerite. Its hardness and high dispersion of light make it useful for industrial applications and jewelry.

Diamonds are specifically renowned as a material with superlative physical qualities — they make excellent abrasives because they can be scratched only by other diamonds, Borazon, ultrahard fullerite, or aggregated diamond nanorods, which also means they hold a polish extremely well and retain their lustre. About 130 million carats (26,000 kg) are mined annually, with a total value of nearly USD $9 billion.[citation needed] About 100,000 kg are synthesized annually.

The name diamond derives from the ancient Greek adamas (αδάμας; “invincible”). They have been treasured as gemstones since their use as religious icons in ancient India and usage in engraving tools also dates to early human history. Popularity of diamonds has risen since the 19th century because of increased supply, improved cutting and polishing techniques, growth in the world economy, and innovative and successful advertising campaigns. They are commonly judged by the “four Cs”: carat, clarity, color, and cut.

Roughly 49% of diamonds originate from central and southern Africa, although significant sources of the mineral have been discovered in Canada, India, Russia, Brazil, and Australia. They are mined from kimberlite and lamproite volcanic pipes, which brought to the surface the diamond crystals from deep in the Earth where the high pressure and temperature enables the formation of the crystals. The mining and distribution of natural diamonds are subjects of frequent controversy such as with concerns over the sale of conflict diamonds by African paramilitary groups. There are also allegations that the De Beers Group misuses its dominance in the industry to control supply and manipulate price via monopolistic practices, although in recent years the company's market share has dropped to below 50%.

Diamonds can occur in nearly any color, though yellow and brown are by far the most common.[6] "Black" diamonds are not truly black, but rather contain numerous dark inclusions that give the gems their dark appearance. When the color is saturated enough in yellow or brown diamonds, a stone may be referred to as a fancy colored diamond by the gem trade, otherwise they are graded for color in the normal color range of white diamonds.[citation needed] Colored diamonds contain impurities or structural defects that cause the coloration, while pure or nearly pure diamonds are transparent and colorless. Most diamond impurities replace a carbon atom in the crystal lattice, known as a carbon flaw. The most common impurity, nitrogen, causes a slight to intense yellow coloration depending upon the type and concentration of nitrogen present. The Gemological Institute of America (GIA) classifies low saturation yellow and brown diamonds as diamonds in the normal color range, and applies a grading scale from 'D' (colorless) to 'Z' (light yellow). The GIA labels diamonds that have more color than a 'Z' diamond fancy, along with those that are any color other than yellow or brown.
