Step cuts are among the oldest cuts of diamond in the world. The first ever diamond that was cut was the ‘Table cut’ – which was a step cut diamond.
They first became prominent in the early 1400s, long before the Round Brilliant cut.
Types of Step cuts:
The most popular Step cut is the Emerald cut diamond. Other types of step cuts are the Square Emerald cut and the Asscher cut both of which are square in shape compared to the Emerald cut. Besides these there are Baguette cuts which are usually thin and rectangular (but not with bevelled corners like an Emerald cut) and these come as normal rectangular and tapered sides.
Unique features of step cut diamonds:
Step cuts are known for their understated elegance owing to parallel “step-like” facets. They have long sleek lines and a subtle gleam. The beauty of an Emerald cut diamond is its rectangular shape, which accentuates the length of a finger. Its four corners are bevelled and it comes with two, three or four concentric rows of parallel step like facets.
Owing to their step like facet structure, Emerald cut diamonds (and indeed other Step cuts as well) have a high level of ‘transparency’, whereby it appears as if one is looking into a pond of absolutely crystal clear water. This is most unlike the Round Brilliant cut diamond, which reflects and refracts light to create a rainbow of colour off its criss-cross facets.
Hence, it is easy to see imperfections in an Emerald cut diamond relative to a Round Brilliant cut. Therefore, it is advisable to select an Emerald cut diamond with high clarity such as Very Slight (VS) or higher. Additionally, the more colourless this diamond is (D or E colour), the more ‘crystal clear’ will it appear – you wouldn’t want a low colour diamond with a brownish tinge of colour to it.
The only exception with the colour factor is if one prefers Fancy colour diamonds and selects, say, a beautiful Cognac, Champagne, Yellow or Pink colour emerald cut diamond.
Tips when buying an Emerald cut diamond:
In summary, if one were considering buying an Emerald cut diamond you would want to ensure that:
It is a high colour and clarity, say: D or E colour and Very Slight (VS) or higher clarity;
Ensure that the sides of the diamond are parallel and its bevelled corners are relatively even and not obviously unequal in the length of the bevel;
Be aware that due to the mirror like reflection created by long parallel facets, the colour may appear to vary when viewed at a certain angle through different rows of facets.
Ensure that the length to width ratio is between 1.50:1 and 1.75:1 so that the diamond is nice and rectangle but not too long and not too ‘squarish’.
Celebrity Step cut diamonds:
Rings worn by Angelina Jolie and Kim Kardashian are examples of celebrities who have made emerald cut diamonds popular in recent times.
