Knox Jewelers offers one free resizing within 12 months of your ring purchase. Subsequent resizing taking place after 1 year from the date of purchase will incur a nominal charge to cover costs. Sizing costs range from $50 - $500 and from 1 to 8 hours of labor depending on the design. While we will recommend a ring size for you, it will be your decision what size you feel most comfortable with. Please note that resizing in Platinum may not be free and can incur a nominal charge to cover the expensive cost of the metal. Also, our free sizing service does not cover shipping costs.

Fingers are Unique
Engagement rings and wedding bands are typically worn on the ring finger of the left hand. Finger shape, size, and length vary from person to person. Some have larger knuckles with thinner fingers and getting a ring over the knuckle is difficult and the ring may spin when it rests on the finger. Others may have tapered fingers which will result in a narrow range of ring size options in order to allow the ring to stay tight on the finger while not compressing the skin. Every finger is unique and finger size will fluctuate due to a variety of factors.
Your Finger Size Fluctuates
Everyone's finger size will fluctuate. This variation will require multiple size measurements of the same finger to develop a working size average. Changes in size are due to:
- Temperature and Humidity
- Summer and Winter Months
- Prescription Medication
- Menstrual Cycle
- Salty Foods
- Wine, Beer, or Liquor
- Time of Day
With this many variables, one size will not fit perfect all the time. Before resizing your ring(s), we suggest at least two size measurements be taken on two different days.
Measuring Your Finger
We take finger size measurements to the 1/8 size. It is up to you, the customer, to decide what size you are most comfortable with. Please note that while all of our measuring devices are calibrated together, other jewelers' tools may not be accurate to ours. Also, a specific size in a petite width band will probably not fit the same finger in a wider band. Wider bands fit tighter and often times will need to be 1/4-1/2 sizes larger to fit correctly.
Comfort fit bands or bands which have a rounded inside edge (the surface that touches the finger), will fit a touch looser than non-comfort fit designs.
Certain finger and/or knuckle shapes require the use of sizing assistants to aid in proper ring wearing. Sizing bumps/balls are the most common and help people with larger knuckles get the ring over the finger and prevent the ring from spinning once rested on the finger.
Sizing Too Many Times, Sizing Too Many Sizes, and Difficult Sizings
Please note that the sizing area on a ring can become fatigued after a couple resizings and that section can wear away faster than other parts of the ring. Also, multiple resizings can lead to different band thicknesses or widths (either larger or smaller) in the sizing area.
Most rings can safely be resized for their first time, one size up or down. Resizing past one size up or down is more challenging and can present greater stress on the ring and the gemstone settings. Certain designs cannot be sized two sizes up or down from the original design.
