Those of you who are considering purchasing a laser engraver will no doubt be interested in using black marble. Just to give you another marketing source consider engraving diplomas and other professional certificates. I normally tell perspective clients that they can put their originals away in a safe place, these won't ever fade and the cost is just a few dollars more than a good frame would be for a paper document.
My photographs cannot even come close to showing the beauty of these diplomas or the pristine quality of the engraved text.
