Oval Halo Size Guide

Five center stone sizes in a white gold oval halo, drawn to scale on the finger. Tap a ring size to see how each one sits on the hand. Measurements are length by width, and the percentage shows how much of the finger's width the ring covers.

All sizes are approximate. Center stone measurements are typical for a well cut oval at each carat weight; every stone's exact measurements are listed on its grading report. Halo accent diamonds grow with the center stone, from about 1.0 mm around a 0.75 ct to about 1.5 mm around a 2.5 ct. With the metal that holds them, the halo adds about 1.5 to 2.0 mm on each side of the center stone. Finger width uses the inside diameter for each US ring size; a real finger looks slightly wider from above. Final measurements are confirmed in CAD before casting.
