Perspective on their fortune
Gold
Everyday luxury

A Carlos Slim Helu & family's fortune is equivalent to 856 of gold, but this may be difficult to value, as we don't usually have a handful of gold bars in our piggy bank.

A standard gold ring typically weighs between 4 and 7 grams. Let's say this one weighs 5 grams. It's usually 18k gold.
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
Carlos Slim Helu & family could buy 228,219,475 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 41 trucks to transport them, But we can be almost certain that Carlos Slim Helu & family will have enough left over to pay for the gas for those trucks.
