L3 Emerald bonuses.

Emeralds are the only Diablo III gem which we know the stats for, thanks to one's appearance in the Artisan introductory movie, in August 2010.

There are 14 levels of gems in Diablo III. Nothing is yet known of the bonuses higher gems will provide, but most fans assume they will grow to very impressive levels, given how difficult and time-consuming it will be to upgrade a gem past level 10.

The only recently confirmed stat is from a normal (level 3) Emerald, as seen in the Gamescom 2010 Artisan video. That gem granted:

• Weapon: +4% Casting Speed.
• Helms: Attackers take 7 damage.
• Other: +7 dexterity

In the Diablo 2 expansion, a level 3 emerald grants:

• Weapons: 17 poison damage over 1 second
• Armor & Helms: +6 dexterity.
• Shields: +22% Poison Resistance
  • Clvl 12 required for all

The numerical bonuses (but not the type of bonus) from gems changed from D2C to D2X, but clearly there are major differences in more than the numbers. Diablo 3 grants entirely different types of bonuses, and categorizes the socketable items differently as well.
