The Jeweler has everything you need to craft powerful Gems and socket them into your gear to boost your character's stats, be it more Damage, Resistances, Life, or Damage Reduction. The best part is that you can change your mind at any time! The Jeweler can un-socket your Gems from your gear without ruining them, for later use. Similar to upgrading Armor and Weapons at the Blacksmith, you can also upgrade your Rings and Amulet to increase their bonus Resistances as well as their extra Stats here.
Unlocking the Jeweler
When your character reaches level 20, you receive a Priority Quest objective to go and see the Jeweler in Kyovashad. Here you are given the task of upgrading a Crude Ruby into a Chipped Ruby. You're given 3 Crude Ruby and need a small amount of Gold to craft your first Gem.
But now where do you put this Gem? As you adventure, you will come across items that already have Sockets in them. Sockets can roll as a bonus stat and allow you to put Gems inside to benefit from the stats listed on the Gem. Your Helm, Chest, Pants, Rings, Amulet and Weapons can all have 1-2 Sockets in them respectively. Killing a World Boss or Treasure Goblin may reward you with a Scattered Prism that can be used to add Sockets to your gear.
I recommend putting that Chipped Ruby from the quest into your Armor for some extra Life.

Gems
You can find and craft many different Gem types, that each have their own stats they provide depending on the Gear-slot they're socketed into. Generally speaking, each Gem grants damage to your weapon, defensive stats to your armor, and Resistances to your jewelry.

Craft Gems
As you come across Gems in your adventures, you can take them to the Jeweler to craft stronger versions. This requires 3 of the lower tier and a small Gold cost to create 1 Gem of the next tier. (Crude to Chipped required 4,500 Gold) Upgrading your Gems will increase the stats they grant depending on the gear-slot you socket them into.

Unsocket
You may want to upgrade the Gems you currently have in your gear, or swap to different ones to gain a stat you don't currently have. Luckily, the Jeweler allows you to unsocket Gems from your Gear for a small Gold cost. This removes the Gem for later use and reopens the slot to allow a new Gem to be Socketed into it. The Gold cost increases as the Item Power of your gear increases.

Add Sockets
If you find an awesome piece of gear that did not generate with Sockets in it, you're in luck. For the cost of a Scattered Prism, the Jeweler can add Sockets to your gear. Scattered Prisms have a chance to drop from World Boss Events, Loot Goblins etc. and you only need 1 to add a Socket to a piece of gear. Not every gear-slot can have Sockets added to them. The list below shows which slots can, and how many Sockets they can have.
- Cap - 1 Socket
- Tunic - 2 Sockets
- Pants - 2 Sockets
- Amulet - 1 Socket
- Ring - 1 Socket
- 1-Handed Weapon - 1 Socket
- 2-Handed Weapon - 2 Sockets
- Bow - 2 Sockets
- Focus - 1 Socket
- Shield - 1 Socket

Upgrade Jewelry
Upgrading your Jewelry increases the Resistances they grant as well as the random stats they rolled. While you can upgrade common and magic gear, it is not recommended. You'd be better served waiting until you have rare and legendary/unique Jewelry before spending your materials. Rare items can be upgraded 3 times, while legendary items can be upgraded 4 times. The cost in Gold and materials increases with each upgrade, and you need special materials to upgrade legendary items.
Rare Ring/Amulet Upgrade Costs:
- Rank 1 Upgrade Cost -Iron Chunk x5 + 4,800 Gold
- Rank 2 Upgrade Cost - [d4-item id=442084]Iron Chunk[/d4-item] x5 +Silver Ore x4 + 11,250 Gold
- Rank 3 Upgrade Cost -Iron Chunk x8 +Silver Ore x6 +Veiled Crystal x3 + 4,800 Gold
Legendary + Unique Ring/Amulet Upgrade Costs:
- Rank 1 Upgrade Cost -Iron Chunk x5 + 6,750 Gold
- Rank 2 Upgrade Cost -Iron Chunk x5 +Silver Ore x4 + 13,500 Gold
- Rank 3 Upgrade Cost -Iron Chunk x8 +Silver Ore x6 +Veiled Crystal x3 + 42,500 Gold
- Rank 4 Upgrade Cost -Iron Chunk x12 +Silver Ore x7 +Veiled Crystal x6 +Abstruse Sigil x2 + 135,000 Gold
Summary
- The Jeweler allows you to craft Gems, upgrade your Jewelry, Socket your gear and remove previously socketed Gems.
- Gems typically add damage to your Weapons, defenses to your Armor, and Resistances to your Jewelry.
- Adding a Socket to your gear requires a Scattered Prism, which have a chance to drop from World Bosses and Treasure Goblins.
- If you decide you want to upgrade or change your Gems at any time, you can un-socket your gear for a small Gold cost.
