I hand cut this freeform focal bead. Measurements in the title and it has a 4mm drill hole with a natural matte finish. This material is from Africa and the dealer said it was "Serpentine Verdite" but those are two different stones! Wikipedia says that ""Verdite is a trade name for two green stones found in Africa. A variety of serpentinite" and "A variety of fuchsite". Judging from it's hardness and how it works I'm guessing it's more of the serpentinite variety. Lovely the colors nonetheless!
