Panastara Diamond Guide
Cushion Cut Lab-Grown Diamond Rings
Cushion diamonds combine softened corners with a square or elongated outline. Their faceting ranges from crisp and brilliant to more crushed-ice patterns, giving buyers plenty of character to choose from.
Square versus elongated cushion
A squarer cushion feels balanced and compact. An elongated cushion stretches the outline along the finger and can create more visual coverage. Compare ratio and millimetre dimensions alongside carat weight.
Match the setting to the outline
Cushions work in minimal solitaires, halos and shoulder-set designs. The best setting is one that preserves the stone's outline rather than obscuring its corners.
Panastara assurance
Panastara pieces are made to order. Where a centre stone is sold as IGI certified, an independent IGI grading report accompanies the diamond. Pieces that fall within UK hallmarking requirements are hallmarked before delivery.
