Howlite Stone Knob
Howlite is often dyed and folks try to pass it off as turquoise...don't let that happen to you! Howlite is a softer stone though, so no running it over or bashing it with a hammer is not OK. This one is shown on an ORB solid brass mount (what I am currently making for my own kitchen!) It works fine on any mount you choose and whichever will include the proper mounting screw.
