Small clusters of rough gems can be found strewn throughout the Template:L. Cut gems can be used to Template:L Template:L, Template:L, Template:Ls, Template:L and Template:L, to create Template:Ls. In addition, raw Template:Ls are required to make crystal glass goods. Rough gems, cut gems and their crystal expressions can be used in the creation of Template:L.

Sometimes, rough gems will be cut into Template:Ls or large gems. The chance of creating a "large gem" or craft is roughly 1 in 3, the skill of a gem cutter does not affect this number at all, only the quality of the finished good produced. Note that these will replace a cut gem and cannot be used to encrust goods. Such crafts can easily reach hundreds, even thousands depending on the gem.

If there is sand on your map, you can also manufacture raw glass, which is the same as a lower-value, uncut gem.

Frequency

At first glance, one might think that any and all gems found in "all stone" have a good chance to be found on/in your map, since stone is stone and your map has plenty of it. However, it appears that there is more going on than a purely random distribution, and that, on any map, a given Template:L will have one or a very few preferred or predominate type(s) of gem(s) found within it, chosen (at random?) from among all those possible and excluding (most) all others.

So, if you find "pineapple opal" on your map, you may find a lot of it, again and again, and no other opals and few other "all stone" gems. The same pattern often appears with gems with more specific environments - altho' any of them might be found, it tends to be only one or two that dominate, even unto exclusion of all other types at times. This needs more research, but don't be surprised when this pattern starts to look familiar.

Value

Gems have base Template:L of 3 in rough form, which is multiplied by the appropriate value modifier from the table below. They gain value after they are cut in a Template:L. Cut gems have a base value of 5. Items can be decorated (encrusted) with cut gems; all such decorations have a value of 10 times the gem type's value multiplier. See Template:L and Template:L. Large gems have a base value of 10.

Unlike other gems, diamonds can Template:L if they come into contact with Template:L.

Rare Gems

Faint yellow diamonds only appear in Template:L (which itself only appears in Template:L layers) and sapphires and rubies only appear in Template:L (which occurs in any sedimentary layers). Colored diamonds only occur in pre-existing clusters of faint yellow diamonds. Star sapphires and rubies only occur within clusters of their peers.

Template:L

Raw glass is treated as an uncut gem. There are three subtypes of raw glass (and, once cut, of cut glass gems):

Gem name	Value	Color	Requires
green glass	2×	☼	Template:L full of Template:L
clear glass	5×	☼	Template:L full of Template:L + Template:L
crystal glass	10×	☼	rough rock crystal + Template:L

Making raw glass requires a dwarf with the Template:L Template:L designated, and, just like working Template:L, it also requires Template:L (either Template:L or Template:L) at a normal glass furnace, or Template:L at a magma Template:L. Like all gems, raw glass has no Template:L modifiers.

Raw gems are only one of the many things your Template:Ls can make from glass. See Template:L and Template:L for more information.

Due to a bug, it is not possible to cut raw clear glass at a Jeweler's workshop without issuing a work order via your Template:L. ^{v0.28.181.40d}
