Ha, since 
, 
, 
are enchantable, it should be worth discussing what is better, Silk Touch I and Fortune III.
In this discussion, we are going to decide to choose from them, using them to following ore: coal, lapis lazuli, emerald, diamond, sphalerite, ruby, sapphire, olivine.
The following ores don't included here because:
Code
Iron, gold, copper, tin, bauxite, galena, tetrahedrite, cassiterite, nickel, tungstate, sheldonite ores always drop themselves.
Fortune dosen't work to uranium, pyrite, cinnebar.
Redstone: fortune works to them, maximum 8 dusts. However, macerating or grinding them yields guranteed 10 dusts.
Iridium: fortune works to them, 1 or 2 gems. However, macerating or grinding them yields guranteed 2 gems.
Sodalite: fortune works to them, 6 sodalite dusts and a aluminium dust. However, grinding them yields as three times as more.My opinions are:
Code
Coal: Silk Touch I. Grinding them yields a tiny pile of thorium dust, which is somewhat valueable. However, if you don't have any industrial grinder, consider choosing Fortune III since it yields more coal.
Lapis Lazuli: Silk Touch I. This is difficult to choose, because mining them with Fortune III yields maximum 24 lapis lazuli gems, but with Silk Touch I yields 12 lapis lazuli gems and 3 lazurite dusts. Similarly to coal, if you don't have any industrial grinder, choose Fortune III.
Emerald: Fortune III. Fortune III works very well to them. You can get 2 tiny piles of olivine dust by grinding them, but they can also be gotten by mining olivine ore.
Diamond: Fortune III. Similar reason to emerald.
Sphalerite: Fortune III. Fortune III doesn't increase drop of sphalerite dusts, however, it does increase probability to drop a yellow garnet very well. Desireable.
Ruby: Fortune III. Fourtune III increases both drop of rubys and probability to drop a red garnet very well.
Sapphire: Fortune III. Similar reason to ruby.
Olivine: Fortune III. Silimar reason to emerald.What's your opinion?
