Is $9,500 to install Silestone Eclectic Pearl countertops a fair price?

I am currently undergoing a 12x24 kitchen remodel, which is a high-end project featuring custom beige cabinets, polished nickel hardware, Thermador appliances, and a real slate floor. I have already spent about $100,000 on the renovation, and the countertops are the last item. I am deciding between Silestone Eclectic Pearl for $9,500 and Mystery White Marble for $16,000. While I am fine spending the extra $6,000 for marble, I am not entirely sold on it, and the Silestone feels inferior. I previously had Quartzite in my last home and liked it, but I want a different look now. I am looking for a creamier/white-based countertop with a bit of gray. Materials like Taj Mahal are even more expensive than marble due to popularity.
