I think there's a bit of confusion since they released 2 new labs. The Alchemist's Research Lab which is under special in the decorations tab and costs 5 each of gold, iron, and ether to build is decorative only.

The Rune Research Lab, which is what Otakunist is thinking of and increases the rune boss encounter rate, is under special effect structures and costs 500 jewels to build plus more jewels for upgrades.
