Zirconium hydride an ore, usually a zirconium silicate, such as zircon. Zirconium is extracted from zirconium ore by removing the oxygen and silica. This process, known as the Kroll process, was first applied to titanium. The Kroll process results in an alloy containing hafnium. The hafnium and other impurities are removed in a subsequent step. Zirconium hydride is created by combining refined zirconium with hydrogen. Like titanium, solid zirconium dissolves hydrogen quite readily. The density of zirconium hydride varies based the hydrogen and ranges between 5.56 and 6.52 g cm. Even in the narrow range of concentrations which make up zirconium hydride,
Cubic zirconia diamond: Cubic zirconia, as a diamond substituent and jewel competitor, has been seen as a potential solution against conflict diamonds and the controversy surrounding the rarity and value of diamonds. Regarding the latter, the main argument presented being that the paradigm where diamonds were seen as rare due to their visual beauty is no longer the case and instead has been replaced by an artificially rarity reflected in their price. This is attributed to confirmed evidence that there were price-fixing practices taken by the major producers of rough diamonds, in majority attributed to De Beers Company known as to holding
