Is Rock Tumbling worth it?

in Alien Pooplast year

I came across this thread with someone in Wisconsin USA
Finding this gorgeous green rock, they think it is a green moss agate however i disagree but im not a pro.

The thread https://forum.rocktumblinghobby.com/thread/90853/large-green-moss-agate

The end result from their tumbling and polishing is here

Watching this end result has made me so so sad a loss of a great rock. Now its boring looking. I dont know i am silently grieving for the rock.

I was searching for what my green rock was and came across the above rock. The rock ID claims epidote but it isnt. The bottom look like some sort of quartz quartzite. Peridote?
