The Louis Vuitton Star diamond cut invention is recited in a family of patents, that includes the US utility patent US2017303647 (A1), titled Cut gem and article comprising such a gem. The patent was granted on October 26, 2017, to Eric Hamers, the French inventor. The patent application was filed by Louis Vuitton Malletiers, in France.
The invention seeks to surpass the brilliance of Princess-cut diamonds by promoting greater light reflection, thereby increasing diamond brilliance. For this purpose, the Louis Vuitton Star-cut diamond has a crown with twenty-four facets, a pavilion with thirty-two facets, and four girdle sides that are identical, each with the distinctive form of an arc of a circle.

The gem is noteworthy in that the crown (7) has 24 facets, the pavilion (13) has 32 facets and in that the four girdle sides (2) are identical in the form of an arc of a circle, the concavity of which is oriented towards the outside of the gem.
