Vintage Sterling Silver Celtic Knot Design w Dyed Howlite or Chalcedony Stones

Hello, and thank you for stopping by! Up for sale is a pair of Sterling silver earrings that were in my mother's jewelry box. I'm guessing that they are from the '50's or '60's. a Celtic knot design and an either dyed Howlite or Chalcedony stone accent on each earring. I took them to a jewelry store to have the materials identified. There is a mark on the back of each earring that the jewler looked through a loupe and told me identifies the earrings as Sterling silver, but it is hard for me to read with the naked eye. Each earring is a little over one and a half inches long. They have fishhook style earring hooks and the Celtic knot/braid design that ends in the round Howlite/Chalcedony stone dyed blue to look like turquoise. Great earrings for a fan of longer/dangle earrings, turquoise, or the Celtic knot design--even Western style jewelry! I will ship the item no more than one or two days after I receive payment. Thank you again for taking the time to stop by!
