The three frontrunners are the laurel wreath, the dodecagram, and the greek key pattern. I personally prefer the laurels, and I can say from personal experience it is extremely easy to find a simple nice pendant necklace for it along the same theme as wearing a cross or Star of David necklace.
If she’s devoted to a particular god, however, I would encourage her to seek out symbolism of theirs in addition to the overall theme. For instance, I have a Greek helmet amulet.
EDIT: That link mentions it briefly, but in more depth: I would avoid the Star of Vergina in particular. It has ties to Greece but it is also heavily politicized in the Macedonian/Greek disputes and you don’t want to get involved in that. Additionally, the labrys is theoretically a Hellenic polytheist symbol…but has been almost entirely appropriated by the lesbian community as a triple-moon symbol. Which is probably why that blogger didn’t mention it. So…we certainly have a STRONG claim to it, but she’ll probably be assumed to be a lesbian more than once.
As an aside though? Pentagrams ARE Hellenic. The Greeks were one of the first groups to use it. Specifically, Pythagoreans used it. So if she wants to use that to represent Hellenic polytheism, she definitely can. I personally prefer something less likely to get me confused with a Neowiccan.
