Suggestions for the ring measurements:
the size of the finger is between 8-23mm generally. You should zoom out the size number in winter
compared with the summer size. If you want the exact size, you can measure your finger at the end of a day, because the size is the largest then.
If it is loose, you can twine a few filament circles in the ring. Soap-suds can be used when the ring is tight.
Measuring Method:
the best way is to ask the assistant of normal jeweler's shop;
You can also measure the diameter of your own ring;
Put an aid (such as nonelastic thread, iron wire or paper tape) around your finger moderately, make notes on the interchange and then measure the length which is the diameter of ring. Find your ring number refer to the size chart.
(Note: please measure carefully for the length gotten by this method is usually longer than normal)
