In recent years,

the promotion of Steinmetz, a diamond dealer,

is very eye-catching. In 24, Steinmetz in Monaco put two diamonds worth $2, in the racing car, and one of them was lost in the crash. In 25, Steinmetz began to sponsor McLaren, and engraved the names of Raikkonen and Montoya on the helmet with diamonds. This year, Steinmetz made a diamond-encrusted steering wheel for Raikkonen to perform in a crystal racing car. The steering wheel will be sold for 4, US dollars, and the proceeds will be donated to charities, including a fund named after the late Brazilian F-1 driver Senna.
