Vintage style sapphire blue pendant with double chain

This is a very pretty antique gold color pendant with a large blue faceted stone. Pendant measures 1 x 1 1/2. It has a double hung chain which measures 15" long. This is nice and long, and is a very pretty piece. It is well made but no marks that I can see to give a clue to the manufacturer. It looks as if it may have been a 1928 jewelry company piece but I can't guarantee it. Excelent condition.
