Vintage Improved Gem Mason Jar Complete with Original Glass Lid and Zinc Ring. Usually the zinc rings are discoloured and rusty but this one is in wonderful condition. All three pieces are in Good Used Condition. Please refer to photos. 

Embossed on one side of the jar is the script 'Improved' followed by GEM and MADE IN CANADA. The glass lid is original to the jar and also has the words 'Improved Gem Made in Canada' embossed into the glass. 

A wonderful piece for both a canner and a collector of vintage jars.
