Large vintage Art Deco sapphire blue and bright ruby red rhinestone and ornate gold tone floral design Czech brooch, Neiger style

Large vintage ornate floral antique gold tone brooch with vibrant sapphire blue and bright red rhinestone accents. In this piece, I love the huge oval blue rhinestone in the centre, set with an open back to let the light penetrate. This piece is large, with a length of 2.25 inches and a width of 1.75 inches. It fastens with a simple hook clasp and pin on the reverse. This is a superb brooch probably dating from the 1920s / 1930s and the classic Art Deco period of Czech costume jewellery: a fabulous piece collectable jewellery. It is in very good vintage condition.
