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 trend line equation is a mathematical formula that represents the trendline. The most common trendline is a straight line and is represented by the mathematical equation.Straight line equation is y = mx + c.where, x, y are the variable and m is the slope of the line.y = mx + c is called as a linear trend line.This kind of trend line works well with a graph that is similar to a line.If data is going up or down at a steady rate, a linear trend line represents data correctly. A polynomial trend line defines a curved line and describes data that fluctuates in an ordered pattern.rend line is a straight line which connects two or more points. It is basically used to analyze a data. Trend lines are one of the basic tools for trading in all markets. Trend lines use a mathematical modal to help accentuate patterns in current data and to help predict future patterns.
