This is a interesting slab of material we call conglomerate or opal nuts in a biscut band.It may be kept as a specimen or you can polish it.This material does have natural holes in it and the sandy areas are hard to polish.In asia the cutters rub fine boulder ironstone [you can collect this in the cutting machine tray by grinding some material away and allow to dry]. They then rub this powder in to the rough and heat it up.Then they apply super glue to it and polish.This gives a good glossy finish.
