Emerald cut, английский
- A square or rectangular cut diamond with diagonal corners. most emerald cut diamonds have between two and four rows of facets that lie parallel to the girdle.
- The emerald-cut is among the most classic of diamond shapes and is usually cut into a rectangular shape. its clean lines come from step-cutting, or parallel line facets and it is always cut with blocked (cut) corners. the length-to-width ratios for the emerald cut is typically 1.5:1 ratio, meaning that the length of the stone is be about 1½ times the width of the stone, which is the correct way to cut a true emerald shape, however, the emerald can also be cut into a square shape where it is referred to as a ‘square emerald’ which can look similar to the asscher cut.
