In an effort to makes its vehicles even more luxurious, Bentley is planning on bringing back an extremely dated interior trim that looks like it's straight out of the Stone Age. That's right, the British automaker is now offering its luxury vehicles with stone trims courtesy of its bespoke Mulliner division. Is there anything that screams luxury as much as a thin slice of stone inside a new Bentley? Apparently the automaker doesn't think so. We've seen some amazing interior features before, but this might one of the strangest.

The material is sourced from "hand-selected quarries" in Rajasthan and Andhra Padresh in India. After the material is sourced, the stones are split from larger pieces and then are cured using a special resin and glass fiber. The stones are then shipped to Mulliner where the division shapes and hand-finishes the materials to be placed inside a Bentley. According to the British automaker, every stone panel is extremely light and translucent, which allows the grain and pattern within the rock to be visible. Director of Mulliner operations, Geoff Dowding, believes that the new material will provide customers with even more customization options and are a first for the luxury brand.

"Bentley is the established expert in the handcrafting of wood and leather, and now we are exploring new, fine and rare materials to offer even more bespoke tailoring and choice to our customers," stated Dowding. The Stone Veneers are available in Falaxry, Autumn White, Terra Red and Copper on the Continental and Flying Spur models.
