LD,
The key thing here is also, as you've mentioned, if dye has been added to stop the discolouration. This is purely a theoretical discussion but doesn't the addition of dye to the oil then make it more than just "oiled"? As for your emerald pieces, it could well be that the oil on a few of yours did dry up but the inclusions aren't so bad that it is noticeable or that over time, it looks the same to you? Or that some are so lightly included and so lightly oiled that it did not matter?
