A good cut can sometimes make a subpar diamond more brilliant but how many facets are necessary for maximum brilliance. We've seen a wide variety of facets used in trademarked diamond cuts but the most facets I have heard of used are on The Movado Diamond. Movado, the watch maker, also creates patented and proprietary 114-facet round and square cut diamonds. They say the cut brings out the brilliance and fire of the stone. I've checked these out in the stores and they do throw off a lot of smaller sparkles but they also cost a bit more than other diamonds of a similar size.
