Coloured square cushion cut lab-grown diamonds combine classical square symmetry (1.00–1.05 length-to-width ratio) with softly rounded corners and vibrant fancy body colour. The square cushion's deep pavilion and generous crown facets draw light inward, concentrating colour saturation evenly across the table while producing a romantic, vintage-inspired silhouette. For trade buyers, coloured square cushions serve as essential inventory for halo mountings, Art Deco revive pieces, and high-margin cocktail rings.
