	Cubic zirconia - Wikipedia, the free encyclopedia
		Cubic zirconia is, as its name would imply, crystallographically isometric, and as diamond is also isometric, this is an important attribute of a would-be diamond simulant.
		Under shortwave UV cubic zirconia typically luminesces a yellow, greenish yellow or "beige." Under longwave UV the effect is greatly diminished, with sometimes a whitish glow being seen.
		Although cubic, it was in the form of a polycrystalline ceramic: it was made use of as a refractory material, highly resistant to chemical and thermal (up to 2540°C) attack.

	Diamond cubic - Wikipedia, the free encyclopedia
		The diamond cubic crystal structure is a repeating pattern that atoms may adopt as certain materials solidify.
		Diamond cubic is in the Fd3m space group, which follows the face-centered cubic bravais lattice.
		The lattice describes the repeat pattern; for diamond cubic crystals this lattice is "decorated" with a motif of two tetrahedrally bonded atoms in each primitive cell, separated by 1/4 of the width of the unit cell in each dimension.

	Cubic Zirconia Silver Necklaces - DragonWeave Jewelry
		Cubic zirconia is the best new trend to hit the fine jewelry market, and when you see these necklaces, you'll know why.
		A generous square of cubic zirconia turned on its side to create a diamond shape, with three tiny cubic zirconia stones mounted on each side to add to its amazing sparkle.
		Light, playful necklace of three cubic zirconia stones artfully set for maximum sparkle in airy sterling silver circles that slide freely along the 16" snake chain, which is slightly stiffened to retain its round curve along the neckline.

	Bambooweb: Cubic zirconia
		Coating finished CZs in a film of diamond-like carbon (DLC) is one such innovation, a process using quartz and topaz has also been adapted to cubic zirconia: Vacuum-sputtering an extremely thin layer of metal oxide (typically gold) onto the finished stones creates an iridescent effect.
		Cubic zirconia is so ostensibly close to diamond that only a trained eye can easily differentiate the two.
		There are a few key features of CZ which clearly distinguish it from diamond, some observable only under the microscope or thermal conductors, exceeding copper.

		Diamond is the hardest known substance, with a Mohs hardness of 10, which varies slightly with the orientation of the crystal.
		Diamond burns when heated in air to 900C; in an inert atmosphere it reverts to graphite slowly at 1000C, rapidly at 1700C.

		A well made round brilliant diamond has 58 facets, is symmetrical, well polished, and reflects a very high percentage of the light that enters it - thus its name - round brilliant.
		In general, marquise diamonds are approximately twice as long as they are wide, but some prefer the look of a longer or shorter stone.
		Pear - A pear or teardrop shaped diamond combines the brilliance and form of a round stone with the elongated elegance of a marquise.

	Diamond, Cultured Diamond, and Cubic Zirconia Comparison
		Diamond, also known as adamant, is a naturally occurring carbon allotrope.
		Cultured diamonds, on the other hand, can be up to 2 carats and come in a variety of colors such as clear, yellow, orange, and pink, making them suitable for jewelry.
		Whereas colored diamonds (such as Jennefier Lopez's pink diamond engagement ring) are extremely rare in nature, they are cheaper to synthesize because they take several days to grow versus several weeks for clear diamonds.

	Superdiamonds? - Scientists discover superconductivity in diamond \| The Newsbulletin \| April 6, 2004
		The discovery offers the potential for a new generation of diamond-based device applications and even suggests that superconductivity in silicon or germanium, which also forms in the diamond structure, may be possible.
		The diamond material was fabricated in Russia by scientists working at the Institute for High Pressure Physics (IHPP) at the Russian Academy of Sciences and brought to Los Alamos where superconductivity in diamond was discovered.
		However, by subjecting a graphite and boron carbide mixture to pressures of nearly 100,000 atmospheres and temperatures of roughly 4,000 to 4,600 degrees Fahrenheit, scientists were able to transform diamonds from a 'supergem' to a superconductor that carries electricity with no resistance at a temperature of minus 450 degrees Fahrenheit.

	EMPG Abstract 1996
		Synthesis experiments for cubic diamond were performed with two systems (1) graphite with mixed potassium and magnesium carbonate and (2) graphite with pure magnesium carbonate (magnesite) at pressures and temperatures in the 8-10 GPa and 1500-1700oC region.
		Measured carbon isotope d13C values for all the materials, clearly identify the origin of the carbon forming cubic diamond as the initial graphite powder, and not the carbonates.
		These conditions for diamond formation in the presence of carbonate are quite close to a normal mantle geotherm.

		On his previous tour, in 2001-02, Diamond played to more than 1.5 million fans in the United States, Canada and Europe and hauled in $88 million as he sold out 98 of 117 shows.
		Diamond, born to a working-class family in Brooklyn in 1941, dropped out of New York University in 1962 to concentrate on songwriting.
		By then, Diamond had written songs that were more redolent of Broadway show tunes than the early folk-rock hits that established him as an artist.

		The crystal structure of diamond is equivalent to a face-centred cubic (fcc) lattice, with a basis of two identical carbon atoms: one at (0, 0, 0) and the other at (1/4, 1/4, 1/4), where the coordinates are given as fractions along the cube sides.
		Each atom can be thought of as a sphere with a radius of 1/8 of the cubic body diagonal.
