This is a 1940's - 50's copper and faux turquoise ring marked "Solid Copper" made by the Bell Trading Co.  The style of the ring is Zuni and features 5 turquoise colored cabachon stones set in saw tooth bezel cups on a plain copper band.  The ring was sized at one time as is evidenced by a silvery colored material that is only noticeable from the inside of the ring.  It is also a perfect match to a copper bracelet #52 in the copper section of Foxfire's Jewelry Shop.  The ring fits a size 6 1/2.
