Diamond Cuts

What Are Diamond Cuts?

In their natural form, diamonds are just lumps of glittering stone. To turn them into gems suitable for jewelry you buy in stores they need to be carefully cut and polished. Diamond cutting is a highly skilled job and can also be highly stressful - one slip and a valuable stone can be ruined.

The objective of cutting a diamond is to turn the rough stone into a faceted gem. The nature and quality of the cut is one of the "Four Cs" by which diamonds are usually graded and valued, so the choice of most appropriate cut is important. The decision as to which cut to use depends on the shape and size of the original stone, prevailing fashions and the experience of the cutter.

The art of diamond cutting has advanced along with modern technology and the availability of sophisticated cutting tools. Early cuts were much simpler than the modern fancy variety. Antique diamonds from long ago are more likely to have a simple old mine or cushion style cut.

In theory any gem can be cut in any way, however over the years a number of "standard" diamond cutts have appeared. These include:

RoundA simple traditional cut popular in solitaire diamond rings
OvalAn elongated form of the Round often used as the centre of a three-stone arrangement
PrincessA square cut that remains one of the most popular "fancy" cuts
EmeraldA rectangular cut with stepped sides, also known as the Step Cut
RadiantSomewhere between the Round and the Emerald
AsscherAn deeper form of Emerald cut, often square
IdealA cut designed on mathematical principles
Round brilliant and square princesss stones are usually graded for cut according to the AGS scale.

There are, of course, many variations on those themes. At the end of the day your buying choice needs to be guided not just by the cut of the diamond itself but how it will suit its intended use - and recipient.
