Cubic Zirconia. Cubic zirconia (CZ), a diamond simulant, is not only the oldest diamond substitute, but also the most popular. Composed of zirconium oxide (ZrO 2) the mineral is extremely rare in natural form. Discovered by German mineralogists in 1937, zirconium wasnât considered economically feasible.ubic zirconia possesses less brilliance (less sparkle), but has more fire (flashes of rainbow color.) CZ is also very hard, not quite as hard as a diamond, but like a diamond can scratch glass.
A linear line is just a straight line. To graph it, you can use this equation: y=mx+b where m = the slope of the line, and b = the y-intercept of the line, in other words, â¦ where the line crosses the y-axis. 6 people found this useful.he set of all such ordered pairs defines the graph of y = mx + c, called a learning linear graphing.In the equation y = mx + c, the number m is called the slope of the line and c is known as the y-intercept. The y-intercept is the value of y when x = 0.
