Rings of Stone

one of a kind carved stone finger rings.

Sizing your ring

I measure the size of my rings with an industry standard jeweler's mandrel. The chart below converts the actual ring size (Size mm) into some of the popular internationally recognized sizes.

The best and most accurate way to determine ring size is to have your finger professionally measured with a wide band ring sizer like the one shown to the right. Your ring will have a band width of 6 to 12 millimeters (mm). Trying on wedding bands in these widths is the easiest way to determine your exact ring size. Another option is a little plastic gizmo I can send you at a very nominal cost. As your ring cannot be made smaller, every effort should be taken to determine the correct ring size you require. In most cases the rings can be enlarged a half to three quarters size, so, if in doubt chose the smaller size.
