Feather Earrings Sterling Silver Onyx Leaf 925 Southwest

Leaf or feather with dabs of onyx cabochons. Lovely stamped design - solid weighing just under 12 grams. Right and left facings which I love. Shows the time and effort taken to create them. Ok here's what I know about these - I've tried to find the exact same set but there are none. 

When I bought these they were sold to me as sterling. They test as sterling. There are stamps on one earring only 925 and Thailand and of course the fish hooks. Picked them up in Tucson at the gem show many years ago - late 80's.  They measure 1 1/2" inches long excluding the fish hooks. I've had them for years. They were carefully stored and come from old stock - never worn. Very solid pieces. Could use a little rub but I will leave that to the new owner.
