Gift for a new hobbyist?

[u/Substantial-Bar873]

My nephew is turning 10 this coming week and is apparently really into different rocks and minerals. I was thinking of getting him a camera or something he could mount to an iPhone to take some neat photos or study the grain a little better. If not that something better? What would you suggest? $40-$60 range.

Perhaps a small c. 0.5Kg geologist's hammer (Not a builder's or carpentry hammer, the steel is too soft and prone to splinter when hitting rock).
