Genuine tiny faceted black diamond bead. Jet black colouring and extremely flashy and sparkly, as you would expect from a diamond. There may be very slight pitting on the bead - this is absolutely normal, and to be expected, from any black diamond bead. The drill hole is very small. You may be able to use a 28 gauge (0.3mm) with some of the larger beads however we recommend a 30 gauge (0.25mm) wire.
Please note: these are not rough uncut diamond chips, but diamonds which have been individually cut, polished and faceted into beads.
