Black diamonds were introduced by debeers around 1989/90 at the nec spring fair (jewellers trade show). They were a way of using industrial diamonds (grey,brown,white but severly flawed,through to black, usually reserved for drills, tools, abrasives). They sorted the pure black ones, and cut them into jemstones, like regular diamonds. They never really took off, and, because of the black being patchy within the rough stone, there were only small gemstones cut, containing only the uniform dark black areas, of the rough stone. Now with pink diamonds becomming popular (these are usually colour enhanced by radiation) small uniform colour diamonds of different colours are popular. By small we mean in use in pave' setting ("encrusted effect") channel setting of eternity rings, Bling style words/names as pendants, encrsted with small stones. So now, the new "black" diamond is trendy! You will never really see one as a large single stone in a solitare ring. Diamonds, of all sizes naturally occur in differnent "hughes" (rather than bold colours) and a popular yellow hugh is called a canary diamond. Good flawless colour commands higher prices than white, of the same quality. An off shade, (grey, or ununifrorm colour) lessens the price. The "hope" diamond which was featured in the titanic film (it never really was on board in real life, a bit of romance, based on an actual diamond) is 45 carats and the pure blue of a light sapphire, dark blue topaz, only more so! A proccess has now been achieved, to grow in a lab, proper diamonds, that show as genuine on all heat dispese testing equipment as used by retail jewellers. They are chemically, Diamonds. These can be created in any uniform colour by adding metal oxides during growth of the crystal. these must be labelled as created diamond. NB. they are not c.z, or any of the shopping channel simulants. They are not cheap either, compared to c.z, but comparitevly so compared to natural, mined diamond.

Answer 2

Diamonds can even be made in a lab -- they are just not natural. Just like a human being made in a petri dish is just as human as one born from a woman. It's just that the first human wasn't made naturally, but it is still made up of all the parts and molecules that make a human.

P.S. I know this was irrelevant to the question, but I posted it anyway.

Answer 3

Anthracite ­ or as some call it, "hard coal" or "black diamonds" ­ is made up almost entirely of pure carbon, causing it to burn cleaner and longer than bituminous coal. This discovery of anthracite¹s potential spurred investment in Northeast PA and inspired technological advancements and transportation developments. In the 1820's, canals emerged as the primary means for shipment of coal to markets in eastern U.S. port cities. By 1842, and continuing well into the 20th century, the railroad reigned supreme in anthracite commerce.
