I was tidying up my faceting material and found these vials of diamond dust with numbers I don't recognise. They came from a chap in Qld years ago when I was just starting out in faceting and put them aside for later..... :o...many years later in fact. Also with them were a set of almost new copper laps plus 2 unused copper laps (Robilt).
Anyhow just wondering if anyone can enlighten me on the grades these dusts are as mine are all in normal nomenclature ie: 180, 360, 600, 1200 etc. the numbers are 0/2, 4/8, 10/20, 20/40.

Possible they are mesh labels??
If so, 0/2 would be #14,000 grit.
