Not sure the bead or rock type, but the pink may be quartz. As depicted in the pictures, the pink is shorter like a choker versus the black is a bit longer. Both are great for layering for any outfit or aesthetic. I don't have much info on these are they were gifted to me a while ago. But they're in great condition and ready to be worn by someone who will show them off!
