How to measure
MJ Joaillerie is using international ring size, if you do not know your ring size. You might refer to the guidance below and find your perfect match. You can simply use the chart below to measure.
【Method #1 Measure Inner Diameter 】
Use the ring you currently wearing, put in flat against a ruler and measure the inner diameter. As the diagram illustrate below.
【Method #2 Measure Inner Circumference】
Use a shred of nonflexible string or paper strip, wrap around the finger of your desire. Do not tie the string too tight or too loose, and then make a mark of where the string intercrosses. Measure the length of the string and compare with the conversion chart below. One thing to keep in mind, the measurement need to be able to go through the knuckle of the finger, almost everyone’s knuckle is slightly bigger than the finger.

Tips:
- Fingers will differ in various temperatures; fingers tend to be smaller in cold weather, and in the morning. So make sure you measure the finger size at the end of the day, be sure it will fit through knuckle and not too loose that will shift around at the base of the finger. If there are two sizes, you can order the larger one, or pick the size in between.
- Left hand and right hand are not always in the same size; therefore, please measure the finger which the ring is for.
