Which size?
Find your ring size in a minute
Your screen becomes the sizer. On most phones it is already true size, and a quarter lets you check. Then measure the finger you will wear the ring on, with a ring that already fits that finger or with a strip of paper.
1. Check the screen with a quarter
Lay a quarter flat on the screen, over the coin, and move the slider until the coin on the screen is exactly the size of yours. No quarter? Then the circle and the ruler are not to scale: measure your paper strip with a real ruler and set that number in millimeters on the strip slider, then send it to the desk.

2. Measure
Take a ring that fits the same finger of the same hand the new ring will live on; every finger is its own size. Set it on the screen over the circle and move the slider until the circle just fills the inside of the ring.
Size 7, 17.3 mm inside
Wrap a strip of paper snug around the base of the finger, where the ring sits, and mark where it meets. If your knuckle is bigger, wrap it there too and take a size between the two, nearer the knuckle. Lay the strip along the ruler's right edge from the 0. Move the slider until the gold line sits on your mark.

Description
Halo settings exist to frame a center stone without competing with it — here, the oval cut fancy pink diamond commands full attention while a surrounding halo of round brilliants amplifies its face-up size and color saturation. This oval cut pink diamond halo engagement ring pairs that center stone with trapeze-cut diamond shoulders for a silhouette that reads architectural rather than fussy.
Explore women's engagement rings to compare center stone shapes, halo profiles, and setting styles side by side.
