Looks like half of a cloak/coat clasp to me - rotated 90 degrees to the right, the hook would be at the bottom and there should be a matching piece with a large hook for the ring, along with chain that would go on the small hook on your piece. The chain would drape if the ladies outer garment was closed tight, but if she wanted to wear it open, the chain still kept it in place; one like this would be stitched down using the small holes around the edge, some had shanks on the back or rim for stitches, while others had metal prongs to attach them.
