    If you don’t like metal touching your stone try a paint brush hair. It measures .2mm and gives a good reference under the loupe. Readily available off a paint brush. I have only used one brush so far and I am sure there are different thicknesses on different brushes, maybe.

    But who wants to set my stone after the competition with that thin of a girdle? Makes me nervous.

    Peak optical comparator is great for measuring the girdle as well as checking your meets. Several on that auction website for $ 15. range. I paid like 80 new for mine years ago after being recommended by Vern Johnson.

    The Peaks look good. I have a years-old Bausch & Lomb Lenscope Nice instrument, but pricey.
