Vintage Goldtone Red Square Cufflinks Rhinestones

These cool cufflinks have rhinestone accents on top of a deep burgundy red square, set in goldtone metal. I see no maker marks on them. Probably vintage 1930's through 50's I think, as they have the square toggle bars. They are on the light side, not heavy. I think they are just totally cool vintage! Measures approximately 3/4" tall and 1/2" wide.
