Hi Ruth,

    Dimensions of ring mandrels and finger gages are a huge problem for
    those of us that make work based on others finger and ring
    measurements. While it is great that you have a precision mandrel,
    what are you using for ring size standards? There is no national
    standard for ring measurement in the US, you can't go to NIST
    (National Institute of Standards and Technology) who are the keepers
    of all standards of weight and measurements here in the US and ask
    for clarification for the diameter of a size 10 ring. If I say that
    a size 10 is 19.73 mm in diameter and you say that it is 19.5 mm in
    diameter we are both right because there is no agreed upon standard.
    I would respectfully suggest that possibly this is an area for the
    MJSA to get the industry to agree to a standard set of measurements
    and publish such a standard so that we can all have one reference to
    look to for finger sizes but until then it is a moot point how
    accurate the taper and markings are on any mandrel or set of finger
    gages. 

Jim.
