I see there have been a few threads about this already but I have been trying to figure this out for almost two hours I've been turning constantly. I've noticed that one of the gems in my jewel piece is not colored so I am guessing that could be the problem. However, I have backtacked to the bridge, the place where you make the molds, and the telescope room and I can't find a dream piece. Please help!!! Thanks!

Hi there,

that one of the gems isn't colored is not hte problem, if you match it with (e.g.) a red gem on a different jewel, on the nexus it will appear red. Sorry this sound weird, but I cant explain it better (red+yellow=orange.... red+colorless=red).
Did you made new jewels at the forge where you made the molds? Everytime you go there, put the mold in the hole, put gold on the forge and you'll get a new jewel (if you have all dream gems). You'll get the molds when you find lenses for the telescope, switch day to night, look through the telescope, find the right stars and you'll get a mold.
Perhaps you missed one lense and so have one less jewel to put in the nexus?

Yeah, I did make the new dream jewels but I still can't get it to work.

Could you tell me which colors you need for the next door? And which jewels you already have with which colored gems? Maybe we can figure it out with this information.

I was actually able to figure this out. Thank you so much for your help!
