Emerald Cut Diamonds

Emerald Cut Diamonds- This is an eight-sided step cut diamond with a rectangular outline. This cutting style gets its name from a common cutting style that's used for, you guessed it, Emeralds.

Emerald gems are cut from long pencil-like rough crystals. This cutting style gives the best weight retention from the Emerald rough and when diamonds were cut in the same style to match up with the beautiful green Emerald center stone, the Emerald Cut diamonds looked pretty good also, so it became available as a diamond shape. This shape was particularly popular during the Art Deco period. When I see Emerald Cut diamonds, I think of the old movies from the 30's.... these diamonds can be very elegant.

This is not a brilliant cutting style, it is a step cut style which means it has long narrow facets. With a brilliant cutting style there are many small irregular shaped facets on a curved surface around the diamond... so a round brilliant cut will be all "blingy", and yes.... blingy is a very technical gemological term! The step cut facets on these diamonds are fewer and much larger, so there are broad flashes of light as the diamond moves.




emerald cut diamond length to widthFor classic Emerald Cut diamonds, look for a length-to-width ratio between 1.30 and 1.40 to 1. There are also some variations in the amount that the corners are beveled... I've seen some corners just barely cut and others that have been cut back quite a bit. There really isn't an exact guideline to follow here... if the length to width along with the amount of bevel that the corners have seems to work together, then that's all that matters. The prongs are usually placed at the cut corners so once the diamond is set it will change the look by covering the corners.





- Important Take Away Points -
Emerald Cut Diamonds


#1- Because of this step cut style of facets, an Emerald Cut diamond with a low Clarity or low Color could be vary obvious. A well-cut Round Brilliant Cut diamond that is really lively, "blingy", the inclusions along with the body color can be masked to an certain extent... this is not as possible with a step cut like an Emerald Cut. A slightly higher Clarity and Color will be a good idea.... probably no lower than an "SI1" or lower than a "G". Of course, if you look at an Asscher Cut diamond in a jewelry store and it is lower than these parameters but still looks nice then you can realize a savings.... but shopping online you'll need to stick with stricter lower limits of Clarity and Color.

#2- The range of table can be from 60 to 75%, the total depth from 55 to 70%. The most critical aspect will be the angles that the pavilion facets will be set to... the light should roll across the pavilion in a smooth even fashion. The cutter will really have to know what they are doing in order to make Emerald Cut diamonds look alive and not look like a lifeless piece of glass that you can read through.

Emerald Cut diamonds are usually cut from pieces of rough that are kind of flat to begin with, so fashioning this shape will be the best choice giving the best weight retention from the rough.
