We have a diamond, and are looking to create a custom setting for it. The vision is some rather thin band, with a squared off four prong setting, looking something like a vintage ring posted on this site: http://www.etsy.com/view_listing.php?listing_id=22765240&ref=sr_list_7&&ga_search_query=engagement+ring&ga_search_type=vintage&ga_page=3&order=&includes[]=tags&includes[]=title (only with a thinner, more delicate look). The diamond is currently set in another ring. If we can find someone who can make the new setting, we'll get the diamond out of the setting and send exact dimensions (I'm guessing it's about one carat).
