The game writes this both ways at times.I did a quick search on the sub and couldn't see this answered anywhere, so apologies if it has been already.

Only the Hel (r15) Rune does not have a Clvl. Clvl: A character must be this level to equip an item socketed with this rune.All Runes have the same stats when in a Helm or Armor, and only two have different when in Shields.To upgrade runes you are required to use 2 or 3 runes (plus a gem) of the level below the one you want to create in order to make 1 rune of the wanted rank.

Runes only impart their stats once they are socketed directly into an item. This is the Diablo 2 runes list of all the runes in Diablo 2.
