Gems refer to their physical bodies as 'Illusions.' Gems' physical forms typically have characteristics associated with human femininity, but all Gems are sexless and genderless, with the sole exception being the male half-Gem Steven. As such, Gems cannot change the size or shape of their gem, which is the limiter of how small a given Gem can be. Gems' humanoid shapes are projections from their gemstone which can be changed at will, described as being "like a hologram, but with mass," with their only constant feature being their gemstone and color scheme (shapeshifting is generally not permanent, and Gems will return to their "default" form eventually, unless the shapeshifting was done during regeneration). However, the gem is the only true part of a Gem’s body, the only part that is unchanging and, indeed, the only part of a Gem that can be permanently damaged or killed. Gems are characterized by the gemstone embedded somewhere on their body, which is analogous to a brain. Garnet and Amethyst, shapeshifting to play "Steven Tag". However, all known Gems have hair or visors that normally cover where their ears would be, and Topaz can hear despite having gemstones in place of both her ears, suggesting that Gems do not need human-like ears to hear - and, as above, they can shapeshift ears if they need them. It is unclear whether or not Gems generally have human-like external ears, as the same Gems have been drawn both with and without them in different shots. Their bodies seem to be made up of doll-joint-like segments in their base forms (although this isn't always apparent), and they lack features such as breast forms, nipples, or navels, due to the fact that they do not naturally possess reproductive systems (although they can shapeshift such features). While most Gems seen have two eyes, some Gems or types of Gems only have one eye (e.g. Gems tend to appear human-like in appearance (some more so than others) and come in a wide array of colors, appearances, sizes, and structures based on their gemstone type.

Snowflake Obsidian (formerly corrupted).Ask yourself if the area is rounded like rings on a seashell (conchoidal), straight like steps, granular, splintery, or uneven. If not, you will need to strike the gemstone hard enough to break it. If there are chips along to surface, examine the area inside the chips. "Cleavage" refers to the way a crystal breaks.Compare the streak left behind to the streaks illustrated on a streak chart. To test streak, drag the stone across a ceramic plate.If the stone cannot be scratched, it is harder than the substance. If the stone can be scratched, it is softer than the substance you scratched it with. Use the various substances provided in a hardness kit to scratch the surface of the gemstone. Some stones are physically harder than others, and hardness is usually measured by the Mohs' Scale.This includes hardness, streak, and cleavage tests. There are a few identification tests that you may wish to avoid if you need to preserve the gemstone in its current state. Ask yourself if damage tests are appropriate.
