How should a ring fit?

Rings should be snug enough to stay on your finger but loose enough to slide over your knuckle comfortably. You should experience a slight resistance when removing your ring, but not enough to cause discomfort or pain. The ring should not wobble or spin easily on the finger. When is the best time to measure my ring size? The best time to measure your ring size is at the end of the day when your fingers are warm. Your fingers are likely to be smaller earlier in the day and will increase in size over the course of the day depending on diet, time of year and activity.

What if my ring size falls between two sizes?

Jewelers everywhere would agree that when in doubt, always size up. A ring that is too big can always be sized down using simple techniques that can be easily accomplished by a skilled jeweler. Warm weather can also alter the way your ring fits at different times of the year, so choosing a larger size would allow for finger size fluctuations.

How can I determine the size of a ring I already own?

You may take a ring you already own to a jeweler to determine its size by using a mandrel, a tapered cylinder with size markers. You may also use the size chart in the “Existing Ring Method” provided in the printable ring sizer PDF to determine the ring’s size.

How can I determine my partner’s ring size without ruining the surprise?

There are many different ways to determine someone’s ring size without cluing them in on the big surprise. In the case of an engagement, your partner may have shared their ring size with a family member or friend in anticipation of proposal. The next best option would be to find a ring they already own (and wear on the appropriate finger) and measure it using one of the methods provided in the printable ring sizer PDF. Keep in mind that dominant hands tend to be slightly bigger, so make sure you are measuring for the appropriate hand. You may also measure one of your partner’s existing rings on your own finger and mark where it fits. Another trick is to use a pencil to trace the circumference of the inside of one of your partner’s existing rings onto a piece of paper and measure the circumference. If you are still unsure, keep in mind that the average women’s ring size ranges between 5 and 7, with 6 being the most commonly purchased. The average men’s ring size ranges between 9 and 10.

What if I choose the wrong size? Does Your Diamond Gal have a resizing policy?

Your Diamond Gal offers free resizing for most engagement rings, wedding bands and fashion rings up to 90 days after purchase. We only ask that you pay for the cost of shipping. Jewelers can typically alter engagement rings up to two sizes up or down. Beyond that, resizing could compromise the ring's integrity and might require the jeweler to make a new custom band. Eternity bands, which are rings set with diamonds around the entire band, are the only exception. We encourage you to know the precise ring size before ordering an eternity band, as they can only be resized about a quarter size up or down and only if there is enough excess metal in the ring. Otherwise eternity bands will have to be completely remade.
