I found these beautiful little antiqued brass post earrings in an old warehouse in New York's Garment District this summer. Score! And, at $3 a pop, they're an affordable indulgence. Great for gift giving, or for resale (I sell these at shows for $6 - $12/pair).
Sold by the pair, a little larger in diameter than a pencil eraser. These come with either stainless steel or hypoallergenic plastic backs.
