I just got this a few days ago from a vendor on Etsy, Simply Willow.  Her work is somewhat steampunk inspired, and I loved this one when I first saw it.  Its called  Red Key To My Heart Steampunk Earrings.  Here’s a picture of one of them (since I only have one ear pierced I keep the second as a spare or let Aviva wear it in her 3rd earring hole).
