Where do gems drop in Knight Online?

Gems are a Juraid Mountain (JR) reward. The NPC who lets you into JR even says the rare gem you win can be exchanged at the Chaotic Generator. During USKO's 2x JR reward event in 2022, the winning side got 2 extra gems and the losing side 1. Entry rules and rooms: Juraid Mountain (JR) guide: entry level, rooms, Devabird and rewards.

75–76 Green Gem
77–78 Blue Gem
79–80 Yellow Gem
81–82 Red Gem
83 Silvery Gem
83, Rebirth 6 and above (on a win) Fortified Sterling Silver Gemstone

This level table comes from NTTGame's global patch notes; it wasn't announced separately for USKO.

Where do you break gems?

  1. Go to the [Chaotic Generator] in Moradon (857, 785).
  2. Put the gem or fragment into the Chaotic Generator window and break it.
  3. The reward drops into your bag, so free up space first.

The Chaotic Generator takes 27 different items, not just gems: the six JR gems, Fortified Sterling Silver Gemstone, Bifrost's seven sin Fragments, seven Dark Fragments and a few others. The NPC's description says it turns the fragments you collect into random items.

What does Silvery Gem give?

Some of the uniques belong to JR itself: the descriptions of Stone Splitter and Dread Shield say they were made to fight the evil soldiers of Juraid Mountain.

What do Red, Yellow, Blue, Green and Black Gems give?

Every gem has the same uniques, weapons and accessories; the armor pieces and scrolls are what differ:

Pool differences by gem
GemArmor piecesScrollsOther
Silvery Gem Pauldron and Pants none no Silver bar
Red Gem all 5 pieces none Silver bar
Yellow Gem all 5 pieces none Silver bar
Blue Gem all 5 pieces Blessed Upgrade, Weapon and Armor Enchant Scroll Silver bar
Green Gem all 5 pieces the same three scrolls Silver bar
Black Gem all 5 pieces the same three scrolls Silver bar
Fortified Sterling Silver Gemstone Pauldron and Pants none 4 Fortified earrings; no normal earrings

So Silvery Gem has no scrolls, helmets, gauntlets or boots in its pool; the lower gems widen the pool with scrolls and all five armor pieces. The chance of a unique from each gem has never been published.

What is the Fortified Sterling Silver Gemstone?

It came to the global server in January 2024: level 83, Rebirth 6+ players get it for winning JR. It has the same contents as Silvery Gem plus Fortified Minotaur, Cockatrice, Lich King's and Lilime's Earrings. In October 2024 the normal earrings were removed from it, and the JR NPCs in Eslant, [Reserve Knight Captain] Belldan and Rugur, got an "Enhanced Silver Gem Exchange List" option: you can swap a Fortified Sterling Silver Gemstone for a Silvery Gem 1:1.

What are fragments for?

The seven sin monsters in Bifrost (Pride, Gluttony, Wrath, Sloth, Lust, Envy, Greed) drop Fragment of Arrogance, Gluttony, Rage, Sloth, Lechery, Jealousy and Avarice, which you also break at the Chaotic Generator. The pool has weapons like Sherion, Lugias, Avedon, Helenid, Hell Blood, Garp, Elysium, Holy Animor and Syphioric, accessories like Flame Ring, Shio Tears, Imir Ring and Foverin, Gold bars, upgrade scrolls and the next fragment up. Worth knowing if you craft Krowaz weapons: Nightmare Crystal is in the fragment pool. Recipe: Krowaz weapon and armor crafting.

What do Gem of Life and Gem of Experience do?

People mix these up with JR gems, but they aren't broken; they are 30-minute buff items:

Buff gems (30 minutes)
ItemEffect
Gem of Experience Base monster EXP +10%
Gem of Defense Defense +25
Gem of Life HP +250
Gem of Contribution Contribution points +4 (restrictions apply)

Soul Gem is a Knight Royale participation reward; Abyss Gem and Low Quality Gem are quest items. None of the three goes into the Chaotic Generator.
