Take it from the experts: "I recommend model 23202-3...the optical quality is surprisingly good.... You don't have to spend much money to start snowflake watching." This plastic foldout magnifier has two 1.25 inch (30mm) 5X glass lenses that combine to produce 10X for close examination of frosty snowflakes made up of frozen ice crystals; only $5.50.
One customer says this in a Google Review: "...the best field loupes for students studying geology & best price....".

Just the best on the market! Great quality, durability. I use this for more than 10 years with my students for field work.
We use this model in two introductory courses (a general geology course for engineers where 4 exercises cover minerals and rocks, and a mineralogy courses taken by a wide range of students in arts and science programs). Some students prefer its wider field of view to that of the other model we order from Indigo Instruments (their 17-mm glass lens, screw-hinged metal loupe). This loupe is durable, and can stand years of sharing among students learning their minerals and rocks in the classroom. Not designed to be worn on a lanyard, though.
