The diamond cut planning stage is a complex process that requires the cutter to work with unique rough stones. Very often, the location of the inclusions in a rough stone will determine the type of shape to which a diamond may be cut. For economic reasons, most diamonds are cut to retain weight instead of maximizing brilliance. [2]
A diamond cut is a style or design guide used when shaping a diamond for polishing such as the brilliant cut. Cut refers to shape (pear, oval), and also the symmetry, proportioning and polish of a diamond. The cut of a diamond greatly affects a diamond's brilliance—a poorly-cut diamond is less luminous.
An example of this is the marquise cut diamond which was popular in the 1970s to 1980s. In later decades, jewelers had little success in selling this shape in comparison to other shapes like the oval or pear shape. [citation needed] The marquise can be cut into an oval diamond by any diamond cutter with a loss of 5 to 10% in total weight.

Gold ring with Old European cut diamonds, late 1800s, Hallwyl Museum. The earliest diamond cutting techniques were simply to polish the natural shape of rough diamonds, often octahedral crystals.

The cut displays a very sharp brilliance or fire if the diamond is cut to the correct depth allowing good scintillation. It is generally cut with a 1:14 length to width ratio with straight edges. This straight edged trillion cut is usually used for accent gemstones, on either side of a main, larger stone of a ring.
The Wittelsbach-Graff Diamond is a 31.06-carat (6.212 g) deep-blue diamond with internally flawless clarity, originating in the Kollur Mine, India. Laurence Graff purchased the Wittelsbach Diamond in 2008 for £16.4 million. In 2010, Graff revealed he had had the diamond cut by three diamond cutters to remove flaws.
The model also shows that the Hope diamond was cut between 1792 (when the French diamond was stolen) and 1812 (when the English blue diamond appeared). [ 13 ] Finally, according to the Museum's archives, it was Henry Philip Hope , after the death of his brother Thomas, who was the legal owner of the cut diamond until his death in 1839.
