Large screwback concho in nickel silver and black, with a faux turquoise oval stone inlay. The antique finish is a bit dark with not much shine; they are newly made to look old. Each stone is the same light green-blue color but the 'veins' differ from one to the next, which makes the turquoise seem more real - no two are exactly alike.  1-1/2" x 1-1/2". The sheet of metal is about 1/8" thick and the oval 'stone' is raised almost 1/8".  Chicago screw is included, and the total depth of the concho with the screw is around 1/2". They're fairly heavy;  .7 ounce.
