2. Cubic zirconia - Wikipedia

   en.wikipedia.org/wiki/Cubic_zirconia

   2.15–2.18. Cubic zirconia (abbreviated CZ) is the cubic crystalline form of zirconium dioxide (ZrO 2). The synthesized material is hard and usually colorless, but may be made in a variety of different colors. It should not be confused with zircon, which is a zirconium silicate (ZrSiO 4). It is sometimes erroneously called cubic zirconium.

3. Zirconium - Wikipedia

   en.wikipedia.org/wiki/Zirconium

   Zirconium is a chemical element; it has symbol Zr and atomic number 40. First identified in 1789, isolated in impure form in 1824, and manufactured at scale by 1925, pure zirconium is a lustrous transition metal with a greyish-white color that closely resembles hafnium and, to a lesser extent, titanium. It is solid at room temperature, ductile ...

4. Zircon - Wikipedia

   en.wikipedia.org/wiki/Zircon

   Zircon (/ ˈzɜːrkɒn, - kən /) [ 7 ][ 8 ][ 9 ] is a mineral belonging to the group of nesosilicates and is a source of the metal zirconium. Its chemical name is zirconium (IV) silicate, and its corresponding chemical formula is Zr SiO 4. An empirical formula showing some of the range of substitution in zircon is (Zr 1–y, REE y) (SiO 4) 1 ...

5. Zirconium dioxide - Wikipedia

   en.wikipedia.org/wiki/Zirconium_dioxide

   Zirconium dioxide (ZrO. 2), sometimes known as zirconia (not to be confused with zircon), is a white crystalline oxide of zirconium. Its most naturally occurring form, with a monoclinic crystalline structure, is the mineral baddeleyite. A dopant [clarification needed] stabilized cubic structured zirconia, cubic zirconia, is synthesized in ...

6. Super Bowl ring - Wikipedia

   en.wikipedia.org/wiki/Super_Bowl_ring

   The first instance of this was the Redskins Super Bowl XVII ring when many in the front office received rings that were not solid gold and contained cubic zirconia stones (which resemble diamonds). When Tampa Bay won Super Bowl XXXVII , the players and coaches received "A" rings with a diamond-centered Lombardi trophy. [ 14 ]

7. Diamond - Wikipedia

   en.wikipedia.org/wiki/Diamond

   Diamond is a solid form of the element carbon with its atoms arranged in a crystal structure called diamond cubic. Diamond as a form of carbon is a tasteless, odourless, strong, brittle solid, colourless in pure form, a poor conductor of electricity, and insoluble in water. Another solid form of carbon known as graphite is the chemically stable ...
