Gems

**Gems** are custom items that work like accessory cards. Each type of gem gives its own stats or ability. Gems in eRO have different grade levels, ranging from G1 to G10.

Players can cut gems at Gem Cutter after completing one of Petra's Forgotten Temple quests.

Chapter 7 introduces Abel who allows players to assemble G8-G10 gem-cutting books after completing the Forgotten Temple quest 30 times.

Cutting gems require gemstones, respective gem-cutting books, and refine solutions. Different solutions have different 'qualities', ergo different rates of succeeding the gem-cutting process. The higher the grade of the gem that you're trying to cut, the lower the chances are of refine solutions succeeding. The following list is sorted by chance, high to low:

1. Enthiric
2. Low Enthiric
3. Hime
4. Elixir
5. High Ether
6. Ether
7. Low Ether
8. Essence
9. Low Essence
