A bow tie in a diamond appears when light escapes through the centre of an elongated diamond, creating a dark shadow across the middle. This happens when the cut or proportions aren’t properly executed in shapes like ovals, pears, and marquises.
Four-pavilion faceting balances how light reflects inside the diamond, this keeps the middle bright and eliminates the bow-tie shadow.
This isn't a standard cut. True Diamond's Shadowless diamonds are custom crafted, redefining brilliance in elongated shapes.
