||The Classic Shapes
The face-up outline of the gem
- Round: A circular outer edge to the stone, either with a large flat table surface or a curved table surface. This is the most common shape to be found and is the most easily evaluated because there are set standards of evaluation on its proportions.
- Baguette: A rectangular shaped stone with outer trimming edges.
- Oval: Oval shaped rim with elliptical round edges.
- Trilliant: A triangle-shaped stone that is either has a flat table surface or a pointed table surface.
- Heart: Heart shaped stones are normally left flat at the table surface and have many facets along the girdle-line.
- Radiant: A roughly square-shaped stone, although the connecting points may be either sharply defined or rounded. The table surface is often multi-faceted.
- Pear: A round elliptic shape that ends with a point.
- Navette: often called ‘Marquise', this is an eye-shaped stone.
- Emerald: This shape is roughly rectangular, but its four corners slope down along the pavilion of the stone.
