Jewelers Benchpin Forums

I wish every Jeweler used Durston's PrecisionFit mandrels and ring sizers.  Sure we would lose some money on sizing repairs from people who buy junk online and get the wrong size.  The amount of time we have to explain to people that yes, finger sizes are standardized but the manufacturers of most ring sizing equipment do not have high enough quality control to keep their products on the standard which is why we use Durston ... blah blah blah.  It would be so much easier if the standards were actually used. 

From Durston's website:
