The description for Emerald Golem is very specific on treasure.
"An Emerald golem possesses no treasure but if the golem is killed, it crumbles into a pile of worthless powder surrounding the unscathed emerald heart. The heart has the same gold piece value as the emerald had when the golem was created."

Also, the emerald has a standard value of 10,000 gold. So that's your answer, a single 10k emerald.
