Shattuckite has a sky blue complexion with darker blue markings. She has two sets of eyes (only one set in her debut appearance) with ice blue irises and black pupils. She has short, poofy, unkempt off-white hair (long hair in her debut form as well) and plump lips. She has sharp claws on her fingertips (lacking them in her debut.) She has a thick build with a round chest, thin torso, and thick thighs. Her gemstones are embedded in the center of her face where her nose would otherwise be and in her sternum.
She wore a dark navy bodysuit with a navy-grey and sky blue right shoulder strap. The entirety of her bodysuit is this color with exceptions to her right shoulder and a pair of blue "boots" with an upward facing arrow pattern with sky blue toe tips.
She wears a sleeveless V-neck bodysuit with a dark navy-grey section connecting to a Yellow Diamond symbol in the center of her chest. Her top consists of two sideways blue triangles and a malformed black-navy blue sideways rhombus (diamond.) She wears navy-grey armbands. Her leggings are pure white and split off into light navy-grey "boots" with black-navy highlights on her toe tips. Her "boots" are sectioned off with a black-navy and sky blue border.
Ice has an admiration for Quartz soldiers, but she was physically weak, lacking the raw power of a Quartz. So, with this in mind, with blind admiration, Ice used to cooperate with Jasper extensively during their fusion, because she enjoyed the power it brought her. Shattuckite utilized Ice's cryokinesis and Jasper's raw power to make a deadly combo.
Shattuckite used to have a layered voice similar to Malachite's with Jasper being the dominant and, unlike Malachite, Ice didn't have enough will or power like Lapis Lazuli to hold Shattuckite together.
Now, Shattuckite is rowdy and a bit aggressive but she does have a soft spot which comes from Ice. Unlike Jasper, she's willing to talk and listen before going off the handle and just beating her enemies into ground.  She also lost her layered voice.
Shattuckite like Sugilite likes existing and doesn't like splitting up.
Shattuckite possesses standard Gem abilities, bubbling, shapeshifting, fusion, regeneration, agelessness, and superhuman strength/durability.
