The time it takes to resize a ring varies; resizing some rings may take a few hours, while others take weeks. Some jewelers may need to send the ring to other experts, increasing the time resizing takes.
Some of the factors affecting the wait time may include the extent of work to be done on the ring, such as additions or any removals, and the workload of the jeweler. Finger sizes change depending on temperature, diet and physical activity, and it is advisable to measure when it is warm. Plain wedding bands are ideal to use for measuring finger size when purchasing a ring.
