	NOVA \| Transcripts \| The Diamond Deception \| PBS
		MARTIN RAPAPORT: A synthetic diamond by itself is no problem, as long as the industry maintains rules of detection and disclosure, that means scientifically, gemologically, the industry is able to detect that a certain type of diamond is a synthetic, is not a natural stone.
		Synthetic diamonds and natural diamonds, because the nature of the defects are different in both types of diamond, emit different types of light, different types of spectra because the defects are different.
		If you rotate the diamond round, you see these octahedral growths sectors have grown larger, and at the same time that initial small cubic sector has grown much larger as well, so this very simple growth sector structure is indicative of a near colorless synthetic diamond.

	Synthetic Diamonds: Diamond Source of Virginia Diamond Loose Diamonds Education
		Diamond was discovered to be carbon in 1796, and it took more than 150 years from that time until a method of diamond synthesis was invented.
		Diamond labs in Belgium and elsewhere that traditionally analyzed and certified diamonds larger than one carat for color and clarity are now being asked to distinguish between natural and synthetic or artificially colored diamonds.
		While synthetic diamonds are expected to have a market niche of their own in the jewelry industry, the big payoff is expected to be in industrial technologies.

	US Patent 5,861,349 Synthetic diamond-containing material and method of obtaining it
		A synthetic diamond bearing material according to claim 1, wherein a diameter of the pores is within 7.5 to 12.5 nm.
		The particle size of the obtained diamond is 0.3 to 0.06 nm, the CSR size is 4 to 6 nm, the particle shape is round.
		Porous structure of the aggregates of diamond particles with the volume of the pores from 0.6 to 1.0 cm.sup.3 /g and pore diameter 7.5 to 12.5 nm which permits of using lees mass of the claimed material with the same volume proportion of the diamond-bearing material as against that of the prior-art material.

		The nickel /iron inclusions in this synthetic diamond (courtesy DeBeers) are approximately diamond clarity grade SI The responses in Figs 47, 48 and 49 are positive for synthetic diamond.
		In a synthetic diamond, such a sizeable inclusion would show a very dramatic attraction response to a rare earth magnet as in Additionally, the synthetic's inclusion would normally be silvery metallic in appearance.
		These Japanese synthetic diamonds may be identified by their fluorescence, grain lines aligned to cube faces, and strain birefringence patterns.

		The GE team used the press to grow diamonds prior to the announcement of diamond synthesis on February 15, 1955.
		GE went on to become the largest producer of synthetic diamond; De Beers follows, with many other manufacturers also contributing to the annual output of synthesized diamonds.
		Small diamonds are placed at the bottom of the active part of the capsule as seeds for the growth of large diamonds.

		We are in Antwerp, Belgium, in Weingarten's marbled and gilded living room on the edge of the city's gem district, the center of the diamond universe.
		Nearly 80 percent of the world's rough and polished diamonds move through the hands of Belgian gem traders like Weingarten, a dealer who wears the thick beard and fl suit of the Hasidim.
		Diamond microchips, on the other hand, could handle much higher temperatures, allowing them to run at speeds that would liquefy ordinary silicon.

		The coloring of many diamonds is so faint that an unpracticed observer, unless he is able to compare such a stone with an absolutely colorless diamond or to place it against a background of pure white, will fail to recognize that the stone is colored at all.
		Diamonds of a fine green color are distinctly rare, only a few examples being known; the same may be said of red diamonds and, even more emphatically, of blue diamonds.
		Several examples of beautifully transparent rose-red diamonds are known; such, for instance, as that of the fifteen-carat stone belonging to the Prince of Riccia, a few smaller specimens in the treasury at Dresden, and a thirty-two-carat stone, the most beautiful rose-red known, in the treasury of Vienna.

	GIA: Gems & Gemology: Synthetic Diamonds Book
		Synthetic diamonds are one of the most important challenges facing gem and jewelry professionals today.
		The first documented production of very tiny, industrial-quality synthetic diamonds in the mid-1950s marked the culmination of more than a century of scientific research to create the necessary conditions for successful diamond growth in the laboratory.
		This event was greeted at the time as a tremendous technological achievement; and within a few years, the production of "man-made" diamonds was commercialized for important uses in cutting, grinding, and polishing operations and in specialized tools for the working of hard materials.

		Diamondâs extreme wear resistant, thermal, and chemical properties make it an ideal material of choice for orifices and nozzles operating in high velocity or harsh production environments.
		Apart from this improvement the synthetic diamond does not contain cracks or other imperfections in its structure, and as a result implosion events are eliminated.
		âDiamond is already the preferred material of choice in many demanding industrial applications and it is rapidly replacing conventional materials in many harsh environments.

	Diamond Education - Synthetic Diamonds
		A synthetic diamond is a rock that has all the properties (durability, hardness, refractive index, etc) of a natural diamond but was made by man. Not to be confused with simulants (those that look similar to a diamond but don’t have the same properties) like glass, cubic zirconia, moissanite.
		I think I can figure out how to grow a diamond cheaper than it costs to find one.” The problem was very few people were listening and those that did just scoffed.
		The initial ground work for synthetic diamonds began for us with trials that had been done in Russia and the University of Florida in 1996.
