I don’t remember much about the series, but I think there were three teens who were transported from world to world to collect a gemstone in each world to stop some evil wizard person. There may or may not have been animals involved that helped, but I cannot remember if it was actually a part of the series. Each gemstone had a specific color and might have been associated with an element or power of some sort.

I think it’s an older series, as I read it back in the early 2010’s and it was old then. Can’t remember the title or author.

  • Do you recall roughly how many books there were in the series, or how many you read? Also, you recall if the teenagers were boys, girls, or a mix? Commented Dec 8, 2023 at 2:11

    This sounds like the Diadem series by John Peel, as discussed in several previous questions e.g. scifi.stackexchange.com/questions/69463/…

This is possibly a series called Deltora Quest by Emily Rodda. It was originally published around 2000.

There are three main characters (I can't quite remember if they were all teens) but they were going between 7 distinct regions within their world looking for gems from the Deltora belt or something similar to use against the Shadow Lord.

I think there was a Diamond, Emerald, Lapis Lazuli, Opal, Ruby, Amethyst, and I think the last gem was a Topaz.
