Ring Sizing Information
In determining your ring size we offer some helpful information. It is best to have your finger measured by a trained jeweler using the proper tools of the trade. You can do this by trying on sizing rings for the correct fit or by measuring an existing ring on a ring mandrel to determine it's size. We do not recommend using the on-line template charts that you print out and set your ring onto or cut out to wrap around your finger. They should only be used in instances where you absolutely can not obtain a professional measurement and at best you will get a close fit. If your not sure of the ring size needed it is best to purchase in the stock size and have resized locally. That way you are not having to pay for resizing. Where we are not able to physically measure your ring to fit we will only guaranty the size to be as ordered, we can not guaranty the ring to fit. Resizing will require additional sizing fees and exchanging for the correct ring size can only be done at our discretion on the more popular designs.
Another important part in determining your ring size is the shape and thickness of the band on the ring. Rings that span across the top of your finger and wide width bands will fit tighter as they cover a larger surface area. When measuring your finger for fit, mention the width of the band your interested in so your size can be adjusted to accommodate the additional width. Another way to determine on the extra wide bands & rings is to try on similar widths for fit and have the ring measured.
 It is also important to keep in mind when resizing your ring from stock size, it will change the 'look' of your ring due to the proportions of the shank in comparison to the top. As in the example on the left, the same ring in a size 4 looks drastically different in a size 10. This is because the top portion of the ring stays the same size but the shank or band's ratio is changed by the ring being pulled inwards to down size or stretched outwards to enlarge. Keep in mind the ring top or crown measurements will not change when a larger or smaller size is ordered only the shank portion is adjusted. It is not unusual for customer to look at the stock sized image which is usually a 6 or 7, order a size 11 and then be upset that the ring was misrepresented as it was smaller looking in person. The only thing changed is the ring's top half was stretched outwards in order to enlarge the shank to size.
Ring Size Conversion Chart
This chart is for International customers to figure out what their size would be by the United States standards. There also is an inside diameter measurement in both inches and millimeters to figure out your ring size. Please note that measuring with a ruler is not the correct tool to use but will give you a good idea of the ring's size.
