Diamonds may be almost forever,
But I would think that fused silica would work almost as well, and is substantially less expensive.
If you want something exotic, how about ion implantation of Cr+ or Ti+ ions into alumina

deBeers laser-engraves serial numbers onto their (natural) diamonds (to counter the increasing gem quality of artificial diamonds made by, say, chemical vapor deposition). So how about laser engraving data onto cheap chemical vapor deposition thin diamond slices? (One of the ideas had been to make microelectronics substrates from diamond this way, since diamond conducts heat better than silicon).
