neck tie holder

this appears to be a tie holder it hooks into a button hole and has a chain that goes around tie it has a skull and crossbones symbol with tiny red jewels for eyes with three triangles. the top is yellow, the bottom left blue, & the bottom right is red . the skull and crossbones is sitting on the top on the yellow triangle. there appears to be three swords one is stabbing down between yellow and blue triangle into the red triangle, the second stabbing down between the yellow and red triangle into the blue triangle the third is stabbing up between the blue & red triangles into the yellow triangle in the center is what appears to be an open book with a dagger laying on it handle down pointing up from right to left  not really sure if this some kind of organization or society type symbol jewelry but any light that can be shed on this would be greatly appreciated .

Thank You for your time,
