Gem-Knight Master Dia confusion

I just need clarification, as it seems like it's obvious to everyone but me as I couldn't find anyone else who has this issue...

http://yugioh.wikia.com/wiki/Gem-Knight_Master_Dia

I'm hung up on how exactly he is summoned. Based on the card, it sounds like you need to fusion summon 3 Gem-Knights before he is able to be summoned, in which case, what are his materials? However, in the Trivia section for this card on the wiki there's reference that it actually takes 3 nonspecific Gem-Knights to summon him rather than needing special conditions. Or is it that it takes 3 Gem-Knight Fusion monsters?

Clarification please?

Why would it need fusion gemknights? It just says gemknights so any 3 will do, fusion or no fusion.

Ah, I got it now. I was confused due to the text format in DN not going down a line, or even so much as a period, so to me it read "3 Gem-Knight monsters must first be fusion summoned" Rather than having a separate line for the material listed.

I should have known, my bad~
