Cubic Zircons are often meant to mimic diamonds. Since CZs have a more dense specific gravity than diamond -- Wikipedia indicates at least 1.6 times that of diamond. This means that carat weight would be less for the CZ to equal the carat weight of a diamond, both being equal in size.
Using the number 15 indicates that you're looking for a large stone. In this case, you may want to go by measurement and not by carat weight. For example, a 15 carat, round diamond measures about 16.3mm across the diameter of the girdle.
Presenting the data in reverse, a 15 carat CZ will weigh 1.6 times more than a 15 carat diamond: so the equivalent size diamond in weight will be less than 15 carats.
Determining the carat weight of a CZ which is 16.3mm across at the girdle can be made by a jeweler who can weigh the CZ stone and give you its equivalent carat weight.
There are several brand names, but commonly, 'CZ' is a term used to describe fake diamonds.

check a jewelry store.... I'd estimate 30-60 dollars, but hey, I'm probably wrong.
A general second degree equation to three variables ax^2 + by^2+ cz^2 + 2fyz + 2gzx + 2hxy + 2ux + 2vy + 2wz + d=0 represents a conicoid
and equation such a Ax+By=C relates two quantities, x and y, we can generalize to Ax+By +Cz+ as many as wel want...=C where x, y, z etc. are the quantities we are relating Doctor Chuck aka mathdoc
About two carats.
CZ stands for Cubic Zirconia, which is a synthetic gemstone. The difference between a diamond and a CZ is that the diamond is a real gemstone. CZ weighs more than a real diamond and is more affordable.
CZ stands for Cubic Zirconia in regards to jewelery. It is a synthetic (created in a lab) alternative to diamond. The main difference between Cubic Zirconia and actual Diamond is the weight, hardness, and the pricing. CZ weighs more than a diamond of the same size, but is a lot less hard. CZ is usually referred to as "fake" or "faux", as it is not the real thing; but CZ is a lot more affordable than diamond.

It is CZ is a cubic zirconia
When shopping for any type of jewelry, be it rings, earrings, etc., the term CZ refers to cubic zirconia. CZ is simulated diamond, and comes in a variety of grades.
CZ or cubic zirconia are artificially created so they can have a perfect make. Make is the measure of craftsmanship when cutting the diamond. Since a CZ is not cut there really is no make.
