One more....Inlay Earrings, need help identifying

Can anybody help me with this makers mark please ?

Could it be an F T, or a P T ?

It is most likely a shop mark. Do you have any information of where these were purchased, anything might help?

No other info, other than I “saved” them from a pawn shop melt bin

the colors are nice, and the turquoise has a really good look.
