Overview

Sections of Cuttable Gems are sliced away on a Gem Cutting Table until the result matches a target design in the Gem Catalogue. At that point, the cut gem may be removed into your inventory.

Nonstandard shapes may be saved in a Specimen Case (available with some multi-month pre-paid packages). Each case holds one cut gem. The contents of the specimen case may later be loaded onto a table for additional cutting.

In the absence of a specimen case, cut gems that don't match a Gem Catalogue entry must be discarded.

Positioning the Camera

Some players prefer to stand inside the table while cutting. However a good stance to begin with is to the right of Sanding Disk 1, in F6 view. Some players prefer to stand by the pole, with the camera rotated so it is on the rear right of the table. Others prefer the pole on the rear left, so the camera is looking at the face of the gem that will be sliced off by Disc 1. For some cuts you may want to change the camera angle to check on what is going on!

Using the Axis Controls

Getting used to the interface will make your gem cutting life easier. It does come with practice. Start by loading a cuttable gem. The option will come up when you click on the gem cutting table with a cuttable gem in your inventory. Pin the menu for reference.

Practice Session 1: 
* ROTATE the gem on the Z coordinate first. The + and - signs will switch the rotation one way or another. Four rotations brings you back to the beginning. 
* Now try the Y coordinate. The gem will FLIP towards you (-) or away from you (+) if you are facing Cutting Disk 1 at the front of the table. 
* Finally, try using the X axis. The gem will TWIRL either clockwise (+ -check) or anticlockwise (-) around the middle of the front face. 

It's easiest to view the table while using the Explorer's Camera (F6) or Builder's Camera (F7). Adjust your distance and viewing angle until it feels comfortable for you.

Eventually you may want cut gems using the hotkeys, but it makes sense to become familiar with the way the gem and cutting blades work first.

Cutting the Gem

There are three sanding disks. Each disc works in a different plane, and will remove 1 layer of solid gem each time you use it.

Disc 1 works in the vertical axis (90 degrees). Only using Disk 1 will make cubes and rectangular box shapes. Disc 2 works on the edge to edge diagonal (45 degrees to Disk 1). Using only Disk 2 will make diamond shapes, sometimes with interesting edge patterns. Disc 3 works on the corner to corner diagonal. (45 degrees to Disk 2) Using Disk 3 also creates diamond shapes, but in a different orientation.

All you need to cut a gem is one or a combination of these disks to create a predetermined shape, as listed in the gem catalogue. The goal is to sand a gem into one of a number of predetermined shapes. The gem catalog will display a sample gem atop the pole on the table, as a reference.

Making the most of Flaws

All cuttable gems have flaws, in an endless array of random configurations. Most types of cut gem can only be formed by taking advantage of flaws in the gem. For example, the "eyelet" cut requires a flaw two layers deep, surrounded by unflawed gem. The "full eye" cut is harder, requiring a three-deep flaw. Before starting to cut any gem, examine it carefully to see what can be made from it. It is MUCH more economical to look first to see what is in the gem and take advantage of what you have than waste precious cuttable gems by going for only what you need. The rarest sets of flaws might just come up, giving you a chance at a Dragyn's Eye or Full Aidenn Mask, and those chances are not to be missed!

Sculptors sometimes say that they see the statue hidden within a block of stone, and cut away all that is not a part of it. This is exactly how gems are made: The desired cut gem is hidden within the rough stone. Sand away all the bits that are not what you want.

When you have produced an exact match for a cut gem, rotate the gem so it matches the catalogue example and complete the cut by selecting the type of gem you are making from the "finished cutting" menu of the cutting table. If your gem is an exact match for the sample in the catalogue, it will be removed from the table.

Some gem cuts require flaws that are present in only a small fraction of rough gems. Zomboe, an expert gem cutter, has provided this list of rare cuts: Tiki Mask is insanely rare. Others, in approximate order of decreasing rarity, are King's Tomb, Unity, Bridge, Lotus, Ring, Dragyn's Eye, Full Aidenn Mask, Ra's Lantern. If you find a rough gem with the right flaws that can be cut into one of these, it's usually best to do it even if you're currently looking for something else - you'll be glad of it later.

Cut Gem		Carats	Instructions	Rarity	Uses
Aidenn Mask		15	Two flaws next to each other with solid gem on the outside edge. To cut, use Disk 1 to cut away excess from the front and back of the flaws, then use Disk 2 to cut the angled edges.	Rare
Amanti		11	None	All	1 Cut Garnet: Amanti for Test of the Windsong 1 Cut Turquoise: Amanti for Test of the Windsong <Varying Amounts> Garnet: Amanti for Test of the Covered Cartouche

Lotus		19	Specific pattern	Ultra rare
Moorish Arch		15
Osiris Eye		10	Description: A long 3 width flaw with a 2-deep flaw in the middle. To cut, use Disk 1 to remove the excess gem from both long sides. Flip so the 'eye' is at the bottom and pointing towards the front of the table. Use Disk 2 to create a peak and reveal the central eye. Turn back around and position to use Disk 3 to cut the points at the top and bottom.
Prism
Queen's Tomb		18	Single flaw surrounded by a ring of unflawed gem	Common
Ra's Lantern		27	Double-width vertex flaw, with one flaw two-deep, with unflawed gem on remaining three sides of prism	Ultra rare
Reflection		14	Two two-deep vertex flaws next to each other, points touching	Rare
Refractor

Unity		36	Two-deep vertex flaw surrounded by an area of unflawed gem. The trick is to find the configuration of flaw and unflawed gem. To cut, look for a Full Eye surrounded by solid gem, and use Cutting Disk 2 to create the distinctive frame around the central flaw.	Ultra rare
