The quality of cuts plays a major role in deciding a CZ gemstone’s value and beauty. The Four Cs – Color, Clarity, Cut, and Carat – are the qualities we use to grade gemstones. Cuts are graded as follows: (A) Excellent, (B) Very good, (C) Good, (D) Fair, (E) Acceptable, and Lower than acceptable.
Just a Few of the Exciting Styles of CZ Gemstone Cutting
Concave Round– The technology to cut concave facets was developed by the American inventor Douglas Hoffman around 1990. Concave cutting facets are uniquely three-dimensional. They possess length and width defined in the same way as flat facets, but they also have depth to their shape because the cutting and polishing is performed on diamond-charged round cylinders mounted horizontally on the cutting machine. Concave facets refract more of the ambient light and return it to the eye as brilliance.
Rose Cut– While brilliant and step cuts currently enjoy the most popularity, the rose cut is a unique style important to gem-cutting history. Dating back to the 16th century, the rose cut has a round, cabbed flat base and a faceted top. Often in two rows, the facets are grouped so that the very highest part of the stone terminates in a point.
Asscher Style– Asscher cuts look similar to emerald cuts with the most obvious difference being that they are square, as opposed to rectangular. The Asscher cut consists of a square cut diamond with chopped corners, giving the stone an almost octagonal appearance. The Asscher cut is one of the most elegant and sophisticated of all the diamond cuts and is the fourth most popular shape for diamond engagement rings in the world today.
The online Cubic Zirconia gemstone market is full of sub-standard polishing, poor cut, misaligned angles. This is the main reason the demand for custom cut CZ gems and lab-created diamonds is growing among the gem lovers and collectors. Gemstones should be cut with proper proportions to maximize the light that is returned to the eye.
