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
The Solara sets a 1.50 carat natural round brilliant diamond in 18K gold. From the top it reads as a clean solitaire: four prongs, a slim polished band and nothing to pull the eye away from the center stone. Turn it to the side and a hidden halo of small round diamonds circles the base of the head, adding sparkle from every angle.
The ring is two-tone, with a yellow gold band and a white gold head. The white gold setting keeps the diamond looking bright and white, while the yellow band gives it warmth on the hand. The center diamond is G color, which is near colorless, and SI2 clarity. A round brilliant is cut to return as much light as possible, so it is the most sparkling shape you can choose.
