Hello,
I purchased a Grey Taj Mahal Quartzite slab from a stone yard a few weeks ago ( see before picture).
After getting it from the fabricator it is now flecked with green over the entire surface and the previous grey veins and are now quite green in parts.
My internet search says it could be due to how the sealer was applied to the quartzite.
The fabricator says it’s normal for grey quartzite to turn greenish over a few weeks time.
What do you all think?
Any way to remove the green and return the stone back to its original color?
Thank you!
