But it’s actually a veneer of stone made to look like a cafeteria counter-top.
Fatuously, the sales pitch makes a point of noting the stone is 200 million years old. Most stone is very old. 200 million years is nothing. You would have to be very ignorant of the age of the earth to feel 200 million years is a special number. I think the reasoning for stressing the age of the stone is derived from the world of vintage wines. Older vintages are indeed rarer. A 1970 is probably rarer than a 1980. A 1930 would be priceless and scarce.
By extension (and wrongly) a 200 million-year old thing suggests ultra rarity. But old rock is not rare. The world is made of rock much older (try billions of years older). Old rock is as unusual as dust or rain. What makes stone valuable is not its age but the source which is why precious marble carries a name such as Carrera and the highly regarded Travertine is sold for its appearance not its age. Bentley probably also use silver in the car and that’s as old as the universe.
Isn’t the problem with this material, this old rock, that it’s semantically wrong. You walk on stone. Stone is used in a kitchen because of its smoothness and strength. Wood is not quite so semantically-tied to a function, it’s a kind of plastic, it can do anything. Bentley have introduced a material associated with the kitchen and not, perhaps as intended, the palace.
Stone also belongs in the mausoleum or sepulchre or makes up an ancient monument. In addition, it’s pretty tasteless. The interest with wood is the almost-patterning. Stone has random flecks and random-flecks are often used on floors and heavy-duty surfaces such as train interiors. Stone is also fabulously heavy which is not what you want a car to be even if the effect of some material choices necessitates it. Heaviness is an acceptable price for structural elements but entirely wrong for decorative ones.
