Do pink diamonds grow naturally in the Earth?

Do blue or pink diamonds grow naturally in the Earth?

1. diamonds are rock- they don't "grow" anywhere as they're not alive. technically speaking they are smushed coal... thats how they make
2. The Argyle diamond mine in Australia produces pink diamonds. Blue diamonds also occur naturally, but they are probably the rarest colored diamond. The Hope Diamond is a blue diamond.
3. yes they do except that when u come across them, mostly u dont realise they are there
4. Yes, they do! Traces of other metals "contaminating a naturally transparent carbon frame" can give a colored tint to diamonds and other gems.
5. yes, and they are very very rare.
6. Diamonds occur in a restricted variety of colors — steel gray, white, blue, yellow, orange, red, green, pink to purple, brown, and black. Colored diamonds contain interstitial impurities or structural defects that cause the coloration, whilst pure diamonds (which are exceedingly rare) are perfectly transparent and colorless. Diamonds are scientifically classed into two main types and several subtypes, according to the nature of impurities present and how these impurities affect light absorption: Type I diamond has nitrogen (N) atoms as the main impurity, commonly at a concentration of 0.1 percent. If the N atoms are in pairs they do not affect the diamond's color; these are Type IaA. If the N atoms are in large even-numbered aggregates they impart a yellow to brown tint (Type IaB). About 98 percent of gem diamonds are type Ia, and most of these are a mixture of IaA and IaB material: these diamonds belong to the Cape series, named after the diamond-rich region formerly known as Cape Province in South Africa, whose deposits are largely Type Ia. If the N atoms are dispersed throughout the crystal in isolated sites (not paired or grouped), they give the stone an intense yellow or occasionally brown tint (Type Ib); the rare canary diamonds belong to this type, which represents only 0.1 percent of known natural diamonds. Synthetic diamond containing nitrogen is Type Ib. Type I diamonds absorb in both the infrared and ultraviolet region, from 320 nm. They also have a characteristic fluorescence and visible absorption spectrum (see Optical properties of diamond). Type II diamonds have very few if any nitrogen impurities. Type IIa diamond can be colored pink, red, or brown due to structural anomalies arising through plastic deformation during crystal growth—these diamonds are rare (1.8 percent of gem diamonds), but constitute a large percentage of Australian production. Type IIb diamonds, which account for 0.1 percent of gem diamonds, are usually a steely blue or grey due to scattered boron within the crystal matrix; these diamonds are also semiconductors, unlike other diamond types (see Electrical properties of diamond). However, an overabundance of hydrogen can also impart a blue color; these are not necessarily Type IIb. Type II diamonds absorb in a different region of the infrared, and transmit in the ultraviolet below 225 nm, unlike Type I diamonds. They also have differing fluorescence characteristics, but no discernable visible absorption spectrum.
7. PINKS,BLUES,WHITE OR ANY OTHER COLOR, DIAMONDS ARE DIAMONDS When other minerals adjoin them they change their color,according to the color of that mineral. If they are Artificially made or manufacture in a laboratory we can also change their color and size. Diamonds are the hardest stone,on a hardness scale. These are made up of CARBON Atoms,in highest temperature and pressure conditions. Takes millions of years. Now a days we can also manufacture a diamond by the bones of our near ones who are died.
