There are three manufacturing professions in the game. Players who have reached level 3 can choose the profession of alchemist, sorcerer or jeweller. The Jeweller profession is the study of gems, the processing and cutting of precious stones, and the charming of magic runes. The profession is taught by masters 
Korundum and 
Esmeril in the Guild of Artisans at City Squares of Dartrong and O'Delvays.
In order to find out what items you can create, look in the professions window by clicking on the "professions" button on the right side of your screen.
In the open window to the left you can see your current skill level, as well as the maximum skill.
Just below that there is a button which you can use to resign the profession. Be careful! If you resign a profession, you will be deprived of all experience and knowledge obtained, including already learned recipes!
The maximum skill level depends on the character's level:
On the right hand side of the profession menu there are three tabs: Selected Recipes, All recipes, and Available recipes.
The tab Available recipes will show all recipes that you can learn on your current skill level. Click "Learn" to learn the recipe and then it will appear in the All recipes tab.
The color of the recipe's name depends on the probability of increasing your profession skill level:
Orange - very high probability of increasing your professional mastery;
Violet - high probability of increasing your professional mastery;
Blue - average probability of increasing your professional mastery;
Green - low probability of increasing your professional mastery;
Gray - minimal probability of increasing your professional mastery.
In the All recipes tab you can not only view all your recipes, but also select some of them, so that they appear in the Selected recipes tab and you have a quick access to your favourite and most frequently used recipes.
If you hover your mouse over the recipe's name, you can see what ingredients are needed. You can also click the "+" icon next to the recipe to view necessary ingredients. When you have enough of all required resources, you can click the Create button.
A certain time must pass between production of the same items, and the remaining time is shown in the Remaining column.
This time is reduced if you have the Premium account level 2 or higher. You can also use the Workshop in your Estate to speed up the production process.
Reminder: producing items in Workshop does not increase professional skill and does not award increased production bonus.
Every time you create items you will also get a message in chat:
Sometimes, if you are lucky, you can receive some of the more valuable items instead of those you were making. Your production can also be doubled:
If by creating the items you have managed to increase your skill level, you will also be notified in chat:
When you create items using the Jeweller profession, you can receive elements of Jeweller's Inventory collection:
When you use the Jeweller's Reward Statue, you will receive Sign of the Master (10 pcs), which can then be spent on various useful items in the Professional Shop in Guild of Artisans.
Skill level
If you want to increase your skill level faster, you can use Master Jeweller Spirit Sphere – it will increase your skill level by 5 points (but no more than the maximum skill for your level). You can also use Advanced Jeweller Skill Scroll which will immediately increase the skill to the maximum level for your character.
If you decide to resign or change profession, but you would like to go back to being a jeweller at some point in the future, you can use Saved Jeweller Skill to save your current skill level. Remember that the profession will be abandoned automatically after you use the scroll. You can check the level of your saved profession in Attributes tab in your backpack. It is possible to save more than one profession. When you decide to restore your saved level of jeweller profession, talk to Korundum or Esmeril in the Guild of Artisans.
Double production
There are several ways of increasing your chance of double production.
After studying Artisans Legacy Code, you can choose one of three talents related to professions. Chances of success during craft talent will increase your chance of doubling the production.
The chances of creating double the amount of item will also temporarily increase if you use Success of the Artisan Elixir which can be purchased in the Professional Shop in Guild of Artisans for Signs of the Master.
During Mirror Magic event you have a chance of winning rare prizes – artisan's bags which not only have plenty of room for your professional tools and resources, but also increase your chance of receiving double the amount of product made.
Your artisan's bag can be improved with a bezel which also increases the probability of doubling production.
There is also a symbol which can increase your chance of doubling production by 110%. It can be applied to gauntlets and pauldrons.
Please note that it is impossible to obtain double the amount of produced items (or higher value items) when producing powders and reagents.
