My fingers are mostly size 4 1/2, and I just felt like there was no point for a class ring that small. Also, it's not particularly common in Canada

Here's a comparison of my Grandfather's UPenn Naval ROTC ring (c. 1937) and my Otterbein ring 2007.

I love how his ring has been worn smooth...I think the stone is an onyx
