Yard Sale/Fair Find

Had to post my Fall Fair find ~ it was so lovely I purchased this little orchid pin along with some other costume jewelry at a Fall Fair/Yard Sale, at a local nursing home fundraiser. When I got home I was checking out my purchases and discovered it was more beautiful than it had appeared earlier. I got my magnifying glass and searched for a mark. Discovered on the 'net that it is by Whiteside & Blank, early 20th century, it is 14k, stunningly enameled and I believe it has a small diamond in it.
