Pink and conrnflower blue beach glass ring features two rare finds gently tumbled in the waters of the St. Lawrence River. They are inset in an adjustable silver plated band.  This makes a pretty good thumb ring too. What was this? The pink glass is most likely a piece of depression era glassware, and cornflower blue was used prior to 1900 before printed labels were in use. It could have been from an early bottle of Milk of Magnesia or Bromo Seltzer.
