Any idea as to the maker of this 925 earring? The letters of the hallmark, despite their clarity, to me remain unclear. Can't tell if the first letter is a T or an F or a lowercase r. The second letter looks like an H initially, but the top arms of the H curve inwards giving the appearance of an incomplete R. Your thoughts on the hallmark and any idea as to the age?
