Diablo II Guide: Gems for Armor and Weapons in Lord of Destruction

Basics

Gems in Diablo II are socketable items that add magical effects to socketed weapons, shields, and helms. Helms and shields can have anywhere from one to four sockets, while weapons can have one to six sockets.The expansion, Lord of Destruction, added socketed armor and improved gem buffs.

There are seven types of gems, each with a different effect relating to its color, and five grades of gems which determine the degree of effect. You can't remove gems once they go into a socket, so take careful consideration before you use them. Save more valuable gems for rare and powerful equipment and vice versa.

Grades of Gems

The five grades of gems have a restricted use based on your character level:

  1. Chipped – Requires character level 1. Selling price: 250 (500 for Skulls).
  2. Flawed – Requires character level 5. Selling price: 750 (1500 for Skulls).
  3. Normal – Requires character level 12. Selling price: 2500 (5000 for Skulls).
  4. Flawless – Requires character level 15. Selling price: 7500 (15000 for Skulls).
  5. Perfect – Requires character level 18. Selling price: 15000 (30000 for Skulls).

There are two ways to upgrade a gem. The first is to touch a gem shrine, which upgrades one random gem in your inventory. If you want to upgrade a specific gem, drop everything else so it becomes the only gem in your inventory. The second way to upgrade a gem is to transmute three of the same quality gem in the Horadric Cube. This will create single new gem one grade higher.
