Talk:Sardonyx's Room/@comment-27159162-20160813202218/@comment-27997069-20160816112409

TL;DR: there are a ton of room combinations, equal to or greater than the number of fusions, of which there are many we still haven't seen.

Stevonnie's room would just be Rose's room; I assume it's the combination of the gems on the door that creates the different rooms, and each possible fusion of the 5 yeilds a different room, for a total of 30 combinations, if you count the ones involving Ruby and Sapphire individually (Which would be cool, but I doubt they'd defuse to then fuse with the others.)

If you just count Garnet as one gem though, (as is her preference) there become significantly fewer:

Steven, Pearl, Amethyst, Garnet, Smoky, Steven & Pearl (Rainbow Quartz? Probably), Steven & Garnet, Opal, Sardonyx, Sugilite, Alexandrite, Steven & Opal, Steven & Sugilite,  Steven & Sardonyx, and the Temple Fusion (Steven & Alexandrite, or all of them together.)

Plus, there are a lot of different ways the gems could go about forming all of the above mentioned combinations(Sugilite and Steven is the same as Smoky and Garnet, for instance), and this doesn't even go into fusions involving just Ruby or Sapphire and not both of them; and of course this also doesn't take into account anything having to do with Lapis, Peri, or Jasper.
