if the rock contains an ore, then metal. diamonds, gold, other precious stones / minerals.
Many rocks contain minerals that contain metallic elements. Rocks that contain metallic elements that can be economically refined into quantities of useful metals are called metallic ores. Bauxite, for instance, is the common rock ore which is refined to produce the metal aluminum.
Kimberlite is a rare, blue-tinged, coarse-grained intrusive igneous rock that often contains diamonds. Some kimberlite deposits have been found in Western Kenya.

Kimberlite
Diamonds are the hardest rock.
Apparently kimberlite pipes -- that can contain diamonds -- are volcanic formations that begin deep within the earth's mantle. Because diamonds and kimberlite -- and other semi-precious gems -- are formed in similar locations, some kimberlite rock contains diamonds. You can read more, below.

Diamonds are sometimes referred as a rocks because of their shape before they are cut for jewelery
Kimberlite is what geologists call "ultrabasic" rock because it does not contain quartz or feldspar. Those are the two most common rock-forming minerals.
all you do is dig to bed rock and then count blocks up sometimes they is diamonds then you dig in any direction
Diamonds are made from carbon, and are called rocks sometimes in their raw, natural form.
