Based on today's gold price (not taking into account the jeweler's fee, shipping, or anything else), that gold ring would be worth $556.3
Giancarlo Devasini could buy 160,524,916 gold rings. That's a lot of fingers and a lot of gifts!!
And if the number of rings is difficult to visualize, all these rings would need 29 trucks to transport them, But we can be almost certain that Giancarlo Devasini will have enough left over to pay for the gas for those trucks.
