Signed Stauer 925 Sterling Silver Sparkly Moissanite? Stud Drop Earrings Bride

Sweet pair of stud earrings, signed Stauer. These earrings look the same as the *dearly beloved* studs currently on the Stauer website. I am not sure if they are exactly the same. They are stamped 925 & acid test positive for sterling silver. I believe the stones may be Moissanite, but am not certain. I have tested the stones with my diamond ii tester & the majority of the smaller stones tested positive for moissanite/diamonds. The larger stones did not. They measure approx. 1/2" from the top of the earring to the bottom & approx. 1/4" across the widest point. Please be sure to view all pics.
