I did not attack you personally. In fact if you, (as you said), tell your customers up front about your use of a sealer to hide minor cracks and flaws in a stone, I applaud you.
It is those who artificially treat their stone, and hide the fact that their stones have been treated that should be despised and exposed.
As for cleaning dust off of stones with Kiwi shoe polish, remember that Kiwi makes a clear polish as well as colored. I would rather that they wash their stones. But as long as they're using the clear polish and not adding artificial color to the surface of their stones, and as long as they're not trying to hide surface imperfections or a poor polish under a coat of shoe polish, I see no problem with it. But on the other hand, if they are trying to artificially color the stones or hide flawed stones or poor workmanship, they should be exposed to prospective buyers. They are being dishonest with their customers.
As for wax used with diamond paste. Waxes of one sort or another have been used as a carrier for various types of lapping or polishing agents for just about as long as lapidary has been practiced. It's an accepted practice. It is not meant to artificially enhance a stone (unless you consider any sort of polishing of a stone unacceptable). Wax mixed with lapping or polishing compounds is meant to be a way to hold the lapping or polishing compound to the stone while being used. Or would you prefer that expensive dry diamond powder be dumped by the pound over a piece while you're trying to achieve a polish.
The FTC may be the controlling force, but in America the GIA and one other group who's name slips my mind right now are the deciding factors in the gem and jewelry trades in this country. They lay out the rules in this country about what is and is not acceptable in the jewelry industry in this country.
And as for your last statement. You just agreed with exactly what I have been trying to say.
