When shopping for an oval diamond, first examine the bow-tie effect — that dark shadow across the center — which should be minimal and not overwhelm the stone. Check the length-to-width ratio, typically between 1.3 and 1.5 for a pleasing shape, and ensure the facets return bright, even light across the whole surface instead of looking dull at the tips. Also verify the girdle isn't too thick, and get a grading report from a lab like GIA to confirm cut, color, and clarity specifics.
