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.

A screen measurement checked with a quarter is a guide, good to about a half size; the desk sizes you right the first time. "Rings here listing it" counts the live listings.
Description
A 1.50 carat lab-grown marquise with 0.50 carats of round side lab-grown diamonds, and every stone on the ring is graded F in color, so the center and the lab-grown diamonds beside it are one even white. The center is VS1 in clarity, on a ring of 14K gold.
The details. The center lab-grown diamond is a marquise of 1.50 carats, the long, narrow shape pointed at both ends. F is the third grade from the top of the color scale, still in the colorless range, and VS1 means minor inclusions that a jeweler finds under magnification. The side lab-grown diamonds are rounds, 0.50 carats together, F color and VS clarity. Prongs hold every stone and leave each lab-grown diamond open to the light. The ring weighs 2.23 grams.
Size and fit. Ring sizes run from 4 to 10, half sizes included, in yellow or white gold. White gold keeps the setting bright around the F stones; yellow gold puts a warm frame around them.
Care. Warm water, mild soap and a soft brush keep the lab-grown diamonds bright, and lab-grown diamonds take the same care as natural ones. Keep the ring away from chlorine and harsh cleaners, store it apart from other pieces so the stones do not scratch them, and take it off for heavy work, since the two points of the marquise are its thinnest edges.
Buying it. Orders in the US ship with a TraxNYC appraisal that records the gram weight, the carat weight and the lab-grown diamond grade. At checkout you can add a warranty plan that covers manufacturing defects for 30, 180 or 365 days. Every order ships tracked. Pay in full at a secure checkout, or over time with Affirm if you qualify.

Why this one
The marquise is the shape that makes a hand look longer: a long, narrow diamond pointed at both ends, and at 1.50 carats it has room to show. This ring carries it in prongs that leave the stone open to the light, with half a carat of round diamonds beside it, all of them F in color, so nothing on the ring pulls warmer than the center. It is the ring people come back to size up.
