The Type of Cushion Cut
Following are three types of cushion cut you should probably know about.
Similar in many ways to the round brilliant is the cushion brilliant which has pavilion facets, which run from the outer edge all the way to the center, making the design resemble a star in shape. The name comes from the pillow-like shape that these diamonds possess.
For a slight variation, you could go with a cushion modified brilliant, which would have an additional facet row below the girdle. This creates a visual effect resembling that of a flower. If sparkle is what matters most to you, a cushion modified brilliant is a good choice. Stones of this cut cost less than cushion brilliants, mainly because of lower wastage at the time of cutting.
Hybrid Cushion Brilliant
For someone who wants the benefits of both a classic look and some extra 
sparkle, a hybrid cushion brilliant diamond may be just the thing. Talk to your jeweler and they will help you better understand this cut.
