Aliasing diamond_(jewel_pet) → diana_(jewel_pet)
Link to alias

Reason:

According to the Jewel Pet Wiki, this cat is named Diana, and her jewel is a diamond.

Related alias:
obsidian_(jewel_pet) -> dian_(jewel_pet)

Probably other jewel pet tags but it's late and I'm about to head to bed... If nobody finds the rest by the time I wake up, I'll hunt them down.

More aliases:

All should imply jewel_pet

Do note: The three "mascot" jewel pets are named after their jewels, so they do not need an alias. This includes Garnet, Ruby, and Sapphire. Others who follow this trend include: Opal, Topaz, Coal, Granite, Japser.
My searches also revealed a subgroup called "Sweet Pet," needs the alias:
honey_(jewel_pet) -> honey_(sweet_pet)
honey_(sweet_pet) -imply> sweet_pet
sweet_pet -imply> jewel_pet

Also! Be careful about tagging these as cub. While they do appear small and cutesy, this is because they all have genetics such as munchkin, dwarf, or toy.

Approved with slight modifications. Because forum #146667 brought up that "jewel_pet" is actually one word (because officially it's "Jewelpet") I also made sure all of the characters we have for this series are aliased to the *_(jewelpet) version of their character tag, in addition to the suggestions here. So that means all of these are fixed and implicated to --> jewelpet now. I also did the same for the few sweetspets we had.
