Editing Diamond cutting (section)

==Recutting==
Due to changes in market desirability and popularity, the value of different styles of diamond fluctuates. All diamonds can be recut into new shapes that will increase value at that time in the market and desirability. 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|date=November 2016}} The ''marquise'' can be cut into an oval diamond by any diamond cutter with a loss of 5 to 10% in total weight.{{citation needed|date=November 2016}} For example, a 1.10-carat marquise shape would be a 1.00 oval cut diamond by rounding the sharp points and creating an oval which currently in the market has a much greater desirability and resale value. The same marquise shape also could become a pear shape instead by only trimming and rounding the side which will be turned into the base of the pear shape.

In the 18th century there was a trend for recutting Indian diamonds to suit English tastes. The [[Koh-i-Noor]]'s original cut weighed a little over 186.00 carats. When it was recut to an oval-shaped brilliant, almost 80 carats were lost.{{citation needed|date=August 2019}}

Other aspects are affected in recutting for value as well, such as the clarity. If an original shape contained inclusions on the tips, the recut would yield an increase in clarity since trimming down to a new shape would yield a cleaner overall finished diamond.{{citation needed|date=November 2016}}
