Rectangular Radiant Cut Diamond on Hand
Put a rectangular radiant cut diamond on your finger and you’ll immediately notice its elegant proportions at work. The stretched rectangular outline with gently cropped corners follows the natural contour of the finger, creating a sleek, lengthening silhouette that feels sophisticated rather than bulky.
Its 70 brilliant facets produce sharp, fiery flashes that travel dramatically along the stone’s length, giving it a lively and dynamic sparkle that’s especially noticeable with hand movement. The cut’s renowned spread makes the diamond look impressively large face-up, often far bigger than its actual carat weight, while the softened corners add refinement and comfort for daily wear.
