Does anyone know the location of a "Gemstone Axe"?

I've looked all over the place and I have no idea where to get one.

those axes rock.
I got one but not sure from where.
nahpui quarter is my guess or perhaps raisu palace.

I think thye drop randomly. I've heard of one dropped form a yeti on shing jea not too long ago

Found a few in the Raisu Place chests.. I think that's your best bet to get 1.

I saw one drop from a Yeti while doing the Yeti Rampage quest. But I wouldn't waste your time hunting them because they don't drop max dmg weapons. Good luck on your search.

Got a few from old Eternal Grove. They would appear to be nearly global.

I get tonnes of them around eternal grove.

Found a crappy one as a gold drop from raisu palace forbidden chest.
