Turquoise earrings -what does the stamp mean?

The earrings I'm talking about are gold and turquoise. It has gold flakes in the center of the oval shaped centerpiece of the 'gold wrapped' heart shaped earrings. It looks antique to me but I'm far from an expert and I'm really unsure if it were made to look antique or if it is actually antique.

The imprints on the back of the earring I believe is "94" and possibly
the letters "AS" with what I believe is a circle with the letter "C". I do apologize, but I tried to take a photo, but I cannot due to insignificant space on my phone.

Maybe you could be of help still and tell me what the imprints might stand for if I gave them correctly that is. Thanks a bunch,
