Marcus has pointed out the advantages of a large diameter loupe when working on bulino, as it can be used at a distance from the eye, rather than in close eye contact, a position preferred by gem workers, etc.
The bulino loupe of choice is the Zeis with about a 19mm lens, usually in two parts with magnification max of x9. Its price is around $150.
x9 magnification loupes are common and most have a small diameter lens. These small lens loupes do not work well except in close eye contact.
If you are curious to try a large diameter loupe at x9 or greater, you may like the inexpensive model shown in the photo. I think it may be purchased for around the $15-$20 range at:

Mine has three lenses to give choices of x3,x6,x9. with large 20.3mm lens diameter.
Clearly, these are plastic lenses at this affordable price, and Zeis is the model of choice, yet I am surprised how good this loupe is. Just the right item to better enjoy the Reno FEGA show if you cannot yet afford a Zeis.
