It is not difficult to measure the ring number of an emerald ring. Here's a simple way to measure it:
1.Prepare tools: a pen, a blank piece of paper, a ruler.
2.Place your finger flat and draw a line directly along the diameter of your finger with the tip of the pen to create an imprint on the paper.
3.Use a ruler to measure the diameter of the finger imprint, which is the data we ask for (in millimeters).
The size of a jadeite ring is usually measured in the inner diameter, and the corresponding number of millimeters is the ring number. For example, if you measure your finger diameter to be 16 mm, then your ring number is 16.
However, this is only a rough estimate, and you may need to buy it a little bigger or smaller, depending on your hearing and comfort level, as temperature changes and slight swelling of your fingers can affect the fit of your ring.
In addition to manual measurements, there are also professional measuring instruments that can be used, such as shank rulers, which are more accurate. Or you can go to a jewelry store and ask them to help you measure.
