Staining/color changes in Juparana Bordeaux granite

Q.Hi, I am beside myself trying to figure out what is happening to the beautiful Juparana Bordeaux granite I had installed last August. Over the past three months, it has gone from large dramatic expanses of salmon-pink and marroon with some black and gray quartz(?) highlights to a much duller overall color due to the appearance of dark blotches covering the crystals and ink black spots that seem to float on the surface. Every crystal seems outlined in black and some of the pink expanses have turned grayish. The patches of grey/black crystal keep changing from light to dark and I've noticed flecks of orange and red concentrating in some areas. Now, there are some white blotches appearing and some of the brighter colored areas seem to have faded. I should mention that Jan. 1, we had a small furnace puff-back that still required top to bottom house clenaing. I was told the soot could not penetrate the granite surface which was supposedly sealed, but I wonder if it has. I also wonder if the stone was somehow color-enhanced at teh factory (the seller says no) and now whatever pigment that was applied is shifting around. I have spoken to a granite and marble refinisher who says he's never heard of anything like this. He tried a poultice in one spot which did not make a remarkable difference. My husband says to embrace the changing stone, but it is very upsetting to lose the beautiful colors I worked so hard to find and it's just wierd not knowing what will happen next! To clean the stone, I have used both a mild "natural" solvent (tea tree oil based)cleaner and a stone tech cleaner and enhancer. These both worked fine for a few months until sometime in January. i hope you can suggets a way to regain teh color I've lost or at least explain what's happening. Thank you!

A.As far as I know all jb slabs are resined by the producer.

Send us some pics to mail@mbstone.com but we dont sell anything that could help your granite get its colors back.

Solvents may degrade the resins over time.It very much sounds like the resin is failing.

Your husband may be right.I dont think they can fixed.

sorry.
