ST Corundum

ST refers to step cut corundum like emerald and Asscher shapes. Step cuts have rectangular or square outlines with facets arranged in rows, resembling steps. This creates a hall of mirrors effect to reflect light. Step cuts display corundum's clarity and color saturation beautifully. The wide facets act like windows into the gem. For emerald cuts, the clarity must be flawless to avoid inclusions showing. Asscher shapes conceal flaws more easily with their cropped corners. Step cuts create a clean, glamorous look perfect for Art Deco styles. The sophisticated step cut highlights corundum’s elegance.
