Dear Ken:
If the edges were polished right, I must assume that your slab has been resined by the factory. The resining process – which overall is very good thing, especially with a “sponge” like Kashmir – does enhance the color of the stone and, of course, the edges, which are obviously not resined, will show a lighter hue.
How to overcome that? With the application of a good quality stone color enhancer.
Your fabricator did that, but with no results?
Why?
Not all color enhancers are created equal, that's why. Or maybe, under the circumstances, they should have tried using a penetrating epoxy. After all, they use epoxy to resin slabs in the factories. But it's too late now.
Solution?
I really don't know. Whatever they applied to your countertop is deep inside the stone and cured by now and will probably prevent a better product from being absorbed by it.
In other words, there's no easy solution and you will have to work things out with your fabricator.
May I ask you now to please read and e-sign our Statement of Purpose at: http://www.marblecleaning.org/purpose.htm?
Ciao and good luck,
