Step-Cut Diamonds Explained: The Complete Emerald & Asscher Guide
What Are Step-Cut Diamonds?
Step-cut diamonds use long parallel facets arranged in concentric rectangles that descend toward the centre of the stone like steps in a staircase. The result is a completely different visual character: deep, architectural, and quietly luminous rather than flashy. The two most popular step cuts are the emerald cut and the asscher cut.
The Emerald Cut: Elongated Elegance
The emerald cut is defined by its elongated rectangular outline with cropped corners. Because of its length, an emerald cut tends to flatter the finger dramatically — the elongated shape draws the eye up and down, making the finger appear longer and more slender.
The Asscher Cut: Vintage Geometry
The asscher cut is nearly square and has a slightly higher crown with more stepped facets than an emerald cut, giving it an even deeper hall-of-mirrors effect. When you look straight down into a well-cut asscher, you see a series of concentric squares pulling you into the centre of the stone.
What Quality Factors Matter Most in Step-Cut Diamonds?
Step-cut diamonds are far less forgiving than brilliant cuts — the broad facets do not hide inclusions or colour. For clarity, we recommend a minimum of VS2 and ideally VS1 or above. For colour, aim for G colour or better in a white gold or platinum setting.
