Tenacious Earthstorm Diamond

Lesser Heroism Sometimes heals bearer of 120 to 180 damage when damaging an enemy in melee. I'm guessing procrate is something along the lines of Crusader.

Basically a Darkmoon Card: Heroism in gem form with +defense.

Things to note:
- heals for around 120 avg.
- both the +defense skill passive stat and the proc will not work if ones gem count doesn't meet the requirments
- When selecting gems one must remember that gems can share multiple colors (typically 1-2 with a few exceptions). So in other words if a gear has 3 red slots and one sticks in Purple (red+blue) Gems the gem count is registered as 3 red and 3 blue or Orange (yellow+red) Gems for 3 red and 3 yellow. Because all gems in the slots are still red one gets the socket bonus and an extra gem count to boot.

Any such affect would be minimal. Although true, this would be a poor reason to choose this gem.
