Yes, if the impact is just right, in the right spot, you can crack a diamond .  That is how "diamond cutters" cut diamonds.

 

The Mohs Scale

Source: Kingzett's Chemical Encyclopedia
The Mohs Scale is used to determine the hardness of solids, especially minerals. It is named after the German mineralogist Friedrich Mohs,
developed in the early 19th century.. As indicated in the charts above & below, Moissanite™ has a Mohs Hardness rating of 9.25.
The scale reads as follows, with the hardness and mineral given from softest to hardest:
 
 
The Mohs Scale is structured where a material rated at a higher number, can scratch the substance with a lower number

Moissanite™ gemstones are such a close match to diamonds that even skilled jewelers cannot tell the two apart. Like diamonds, Moissanite™ gemstones have inclusions and color differences. Charles & Colvard's patented Tester Model 590 (photo below) is the only recommended instrument that has been developed to distinguish Moissanite from diamonds. The tool reliably and easily distinguishes colorless Moissanite™ gemstones

Signity Star™ CZ

Quality

Signity is passionate about manufacturing excellence, for both practical and aesthetic reasons. Practically speaking, our precision-cut gemstones are uniform in size, shape and dimensions for problem-free setting. Aesthetically speaking, they’re alive with sparkle and shine for brilliant face-up appeal. Signity is able to achieve the proper proportions needed to attain optimal fire and brilliance for each gem we offer, no matter how large an order. We pay meticulous attention to symmetry and finish; therefore facets are properly sized and aligned to give our gemstones maximum light dispersion and definition. Moreover, our girdles are uniformly polished allowing for ease in setting, reduction in stone breakage, and consistency you can count on.

Our New Quality Standard for CZ has resulted in the Signity Star, the most brilliant CZ on the market that is second to none!

Every Signity Star gem is precisely cut and polished to such tight tolerances that every one of its facets is ideally matched and aligned. Its exact proportions reveal through a special microscope, the Signity Starscope, an eight-point star pattern known as hearts and arrows in the diamond industry. Round CZ without this pattern is not ideally cut. Only the Signity Star offers superior brilliance in a CZ.

Every stone in each size category is a near perfect copy of each other in dimension, shape and workmanship. This consistency guarantees ease of setting, reduction in stone breakage, and a decline in production downtime and costs.

Scientific Proof:
Only a deviation of one degree results in a dramatic loss of the light return.
The investigation of the light return characteristics of the ideal-cut Signity CZ and the variation of a 1° deviation of the pavilion angle was carried out with a computer simulation.
