Minor Characters/Gems

Minor Gem Characters are Gems who have debuted and been identified, but, as of yet, hold no significant nor recurring roles.

Peridots
Era 2 Peridot were seen in the movie.

Topazes
Two Topazes appear, non-speaking, in a flashback in "Now We're Only Falling Apart" alongside Pearl, Rose Quartz, and three Amethysts. One Topaz has her gemstone on her navel, while the other's gemstone placement is unknown. Four more are seen in the episode, "Familiar". The first two are seen guarding Yellow Diamond's extraction chamber and the other two are seen guarding Blue Diamond's pool chamber, each holding a mace. Three Topazes appear in "Change Your Mind", two of which having previously guarded the extraction chamber in "Familiar" now guarding Yellow Diamond's bubble chamber and a Topaz fusion with a gemstone on each arm. Two Topazes can also seen in Steven Universe: The Movie: one Topaz has her gemstone on her upper back, while the other's gemstone placement is unknown.

Uncorrupted Worm Monster
An uncorrupted gem appears in Steven Universe: The Movie. She is the same type of gem as the Worm Monster, who appeared in "Bubble Buddies" and was uncorrupted in "Change Your Mind", but with a different hairstyle, clothing, and gem placement. Her gemstone is located at her sacral chakra, but appears to be under the skin, like her chest-gem counterpart. Unlike her fellow Gem, her stone appears to only have three connecting stripes rather than five.

She has a semi-transparent body and is noticeably much taller than many other gems shown, standing taller than Snowflake Obsidian. Her outfit consists of two orange wraps with darker spots, one around her chest and another loosely around her hindquarters beneath her gem. Her eye has yet to be seen under her tentacle-esque hair.

Heaven and Earth Beetles
Seen in The Movie.

Watermelon Tourmalines
An uncorrupted Watermelon Tourmaline appears in Steven Universe: The Movie. She has a similar design to the other Watermelon Tourmaline, who appeared corrupted as the Giant Pufferfish in "Beach Party". This Watermelon Tourmaline, with multiple arms, seems to be a fusion (presumably of two Gems of her same type).

Zircons
Two Zircons can be seen in the movie.

Trivia

 * All Gems of the same Gem type also share the same voice (with the exceptions of the Diamonds and different variations of Quartz), albeit with some differences in tone. Their appearances are also nearly identical, excluding gemstone placement and minor outfit details.
