The seeds of "Abrus precatorius" are much valued in native jewelry for their bright coloration. Most beans are black and red, reminiscent of a ladybug, though other colors exist. Jewelry-making with jequirity seeds is rumoured to be somewhat hazardous. There are persistent reports that the workers who pierce the seeds in order to thread them can suffer poisoning or even death from a pinprick, but there seems to be little evidence. An online search found 265 scientific papers referring to "Abrus precatorius", but not one of them dealt with occupational poisoning.
