Antique Class Ring

10K yellow gold antique class ring from 1925.
I have absolutely no idea what school is this from or whom it belonged to but I just could not pass this up. It’s 100 years old! The gold is quite dingy but the filigree and detail is just incredibly lovely! I couldn’t imagine why someone would have ever gotten rid of it. It’s measures 22mm across the top and tapers downs to 2mm at the bottom. Finger size is 7 and it weighs 5.2 grams
