Tiffany & Co. Twist Rope Knot Stud Earrings, Sterling Silver 925

I received as a gift many years ago and wish I returned them at the time because not my style but did not want to offend the person who gifted them to me. I put on several times but always changed earrings before going out. I have long, wavy hair and cannot see them. So basically brand new. I put a picture of them with ruler for a general idea of size. One picture I tried to capture lettering on backings, looks like T&co but you judge for yourself. Let me know if you have any questions.
