Cushion cut diamonds are diamonds that are either rectangular or oval in shape and give an overall rounded appearance that resembles an overstuffed cushion, hence the name. Most commonly found in antique jewellery, cushion cut diamond rings were most popular during the latter part of the nineteenth century and the early part of the twentieth century. Since they were most popular in an era before the invention of electric lighting, they were cut to be most brilliant and impressive when viewed by candle light, and were often alternatively referred to as candlelight diamonds.

A simpler cut than most modern cuts, cushion cut diamonds usually have around 60 facets, while most common modern diamond cuts have eighty or more. Because of this, cushion cut diamond rings have been said to lack the fire or brilliance of other cuts, yet they have a classic appeal that is appreciated by those with a taste for more conservative looks.

Among the most famous cushion cut diamonds are the Graff cushion cut diamond and the Hope diamond. The Graff, at 11.89 carats, is not considered to be overly large compared to other famous diamonds; it is unique in its uncommon color, clarity, and in the rareness of its cut. With a color rating of D, or perfectly colorless, and a clarity rating of Internally Flawless, the Graff cushion cut diamond is both unique and beautiful.

The Hope diamond, one of the most famous and infamous diamonds in the jewellery world, is currently on display in Washington, DC, at the Smithsonian Museum. With a rich and mysterious history and an infamous reputation as a cursed stone that brings a string of misfortunes to its owner, the Hope diamond is one that can inspire curiosity even in those who are not gemstone enthusiasts. The Hope diamond is a dark, smoky blue that comes from trace elements of Boron, with a carat weight of 45.52 and a classic cushion cut, making it as beautiful as it is mysterious.

Whether discussing famous classic cushion cuts in museums, or a grandmother’s engagement ring among family heirlooms, there is no doubt that a cushion cut diamond holds both classic appeal and a contemporary beauty.
