Very pretty, glossy and natural Black Onyx rectangle beads on a 15" strand measuring approx 6x4mm in size with some variations. There are around 61 beads on a strand.

Black Onyx is a solid black form of onyx without the banding (as in Sardonyx) and is another variety of microcrystalline quartz and a form of chalcedony. Our black onyx tends to be very black but can have occasional brown in it, especially in larger examples.
