Another one that has me stumped. Sterling Silver earrings 925 K(?)M

Identifying & Discovering
1

I can’t tell if these are Navajo, but think so. But the hallmark is one I can’t identify. Seems I have a number of these lately. Any help would be appreciated. The first one is actually a front of one, back of the other, and the last is the hallmark. Maybe the K is an object?

Pretty earrings, can not find anything on that hallmark. They are made using casting techniques and that is why I think the hallmark and 925 are not clear, that is part of the cast, which would most likely make them not Navajo made, thanks for sharing.
