First designer signed scarf clip I have come across. This one is signed D'Orlan 1186 (not sure about the last digit). It is a convex swirled circle of brushed gold tone feathers. It is 1.5 inches in diameter and has a strong clasp on the back.
This and many other scarf clips work beautifully as pendants. I tried this one with 3 different chains from fairly fine to fairly heavy and this clip worked well with all 3. This is a heavy clip so its weight keeps it from toppling over and the tight clip will keep it from falling off the chain. If using as a scarf clip, this one is for your heavier silk scarves.
