Vintage G&S mirror necklace

I buy this in a second hand vintage store, it's beutiful vintage mirror mark on the back G&S c ORIGINALS. ..It is known that H & S Originals was a mid-century American costume jewelry company. But other reliable information about H & S Originals is difficult to find and confirm. While researching this company, I did find several magazine ads for the jewelry. These include ads for H & S Originals ..
