A nice vintage Henry Birks & Sons, Ltd. sterling silver presentation ring box of cubed rectangular form with canted corners. "BIRKS" is embossed on the satin lined l interior. It measures 1 1/4" high x 1 1/2" wide x 1 3/4" long, accommodates a single ring. I believe this ring box dates to circa 1940's/ 1950's. These presentation boxes accompanied the acquisition of a very fine diamond or other gemstone ring and could not be purchased on its own. Birks jewelers follows this practice to this day. The box is in good vintage condition with no dings or repairs. Some surface scratching from age and use is evident. It shuts tightly with a firm click and is well aligned. The interior is all original with the edges of the velvet ring holder showing some remnant evidence of silver polish around its edges. This can be removed or cleaned. Stamped sterling on the bottom of the box. These boxes are scarce, so I am happy to have found one in good condition to pass along to a good home. Lid of box is monogramed with the letter "N". I have given it a polish with a polishing cloth but it could use a professional clean and polish to bring it back to an almost pristine condition.
