-In variants with an [[object materials]] system, many more objects including weapons and armor can be made of gemstone, sometimes referred to as '''crystal'''. It is generally a high-quality material for weapons and armor, but such items are very expensive and often hard to come by.
+Some ''NetHack'' [[variants]] add new items made of gemstone, while others that implement an [[object materials]] system make it possible for certain items&ndash;usually [[metallic]] ones&ndash;to be made of gemstone.
