Taking its design cues from the history of pearl diving in the Middle East, the Arabian Gulf Phantom has two-tone paint designed to invoke the waters of the region and the purity of the pearls. The car also gets a shell motif in the coachline and a Mother-of-Pearl clock, plus Mother-of-Pearl marquetry on the picnic tables’ fascia. Interestingly, Rolls-Royce’s former sister brand Bentley had a similar idea for a limited-edition Bentayga.
