Confetti Earrings Tear Drop Cabochon Bezel and similar items

Confetti Earrings Tear Drop Cabochon Bezel Set Oval bezel set stone that I am un sure as to just what it is. Cabochon set into a metal that I am real sure is sterling silver, yet I can't find a mark. Looks to be an older set of earrings and back then, there was no required mark you had to place on items like now days. There is white and it looks like yellow gold of some kind be it plastic or stone I have no clue as this is an estate sale purchase. They are very well made and a treasure for sure. Lever backs even look a bit different than now days. I'm betting on sterling silver with these, but if you get them and don't like them or think so, you are more than welcome to return these to me. I'm debating keeping them. Almost 1-3/4 inch in length from top of wire to bottom of earring. If you know anything about these please do share so I can advertise them the right way here. I am only guessing at the value right now.
