One of the problems in buying a ring online is that there's no possible way to see if it would fit on your finger without actually buying it first. We at Marvolis understand this scenario, so we made a user-friendly ring size measurement guide just for you which you can print out and measure.
Unfortunately, there were a number of customers who were not able to follow the instruction to print at 100% which resulted in inaccuracies. We've decided that it's better to take the guide offline and advise that our customers use the ring size they know they wear or check with a local jeweler to determine the correct ring size.
Our ring size follows standard US ring size.
