Silver925 & Carbon Carbon is bonded to a sparkling silver base with the SF emblem placed to make it appear as if it is raised, and the red stripe in the middle expresses Ferrari's sportiness.
The ring part is also made of silver, and 925 is stamped on both the body and the ring.
The contrast between the carbon and silver creates an impression of solidity, like high jewelry.
