For rings, you can measure your finger size by yourself.
At TimJeweler, we offer extra small to extra large bracelet sizes (US):
5.5 inches for extra small wrists(kids, teenager);
6.5 inches for small wrists;
7.5 inches for regular wrists;
8.5 inches for large wrists;
9.5 inches for extra large wrists.
HOW TO MEASURE
STEP 1: Measure your wrist with a flexible tape measurements or a strip of paper just below the wrist bone, where you would normally wear the bracelet.
STEP 2: If you are using a plain strip of paper, mark your size with a pen or pencil then use a ruler to measure the length, and give your wrist a loose fit to move around.

A good, thick ring, heavy metal. The inside has a slight curve to it that makes it very comfortable to wear, and almost soft feeling on the finger. I've been wearing it for a few weeks now, and the smooth surface shows some mild scratching (as expected with normal wear and tear), but the etched symbols are still crisp and unaffected both inside and out.
My request for the engraving was a little unusual, but they were still able to fulfill exactly as I asked. I'm really happy with this purchase, and may even get a second one!
The only odd thing is that the style of ring recieved was very different from the one in the listing. This one has a flat engraving area, with fairly large bevels both above and below (shown in image), rather than being a simple straight edge.
The ring was absolutely perfect. I could not have been happier.
