Amblygonite

Amblygonite is a Gem first seen, corrupted, in the episode of Steven Universe "Giant Woman". In their corrupted forms, The Geode Beetles of Heaven and Earth are small Beetle-like creatures.

Amblygonite is seen next in Steven Universe: Art and Origins. They are seen uncorrupted, but a name is not specified. Their color pallets, however, indicate that they are a Gem known as Amblygonite, a Gem that comes in the colors Green, Yellow, and blackish purple, such as their color pallets in the show.

We are also treated to seeing a Gem similar to Amblygonite in the fusion Fluorite, first seen in the Steven universe episode "Off Colors".
