I pic up diamond ponies for my daughter here and there when I'm out scouring antique shops. The table i approached was in a very unlit area along a back wall. Much glass to choose from.. grabbed a nice medium purple diamond with good shape and brought it home at a whopping loss of $5. Took a couple of pictures of it cleaned up and in better light.. looks like a bluish tone on top..purple in middle...then off to a clear.
