Sphene is a tall and lanky gem that has four eyes and four arms. Currently her lower legs and the left side of her body are not available, but she is presumably symmetrical in terms of body parts and such. She has bright yellow skin with streaks of an orange-brown color that are reminiscent of Jasper, and she has four eyes, with the top pair being slightly more rounded and covered by her visor, while the bottom pair are slightly more pointed and not under the visor, and all eyes appear to be yellow. She also has no nose (where her nose would be is covered by a gemstone at least) and plump lips. Her har is short and messy and is a light yellow color. She has four arms, with the top pair being thicker and not having wrists but instead having the arms connect to the hands and fingers directly, while the bottom pair are slimmer and less muscular. Her gemstones are on her forehead and her nose/center of face, and they are colored in orange and yellow colors.
She wears a translucent visor that has a triangular shape and covers the top half of her face and is very similar to Peridot’s visor before her regeneration. She wears a standard Homeworld uniform and it is a dull brown color with black straps that make an X shape and have a YellowDiamond insignia in the center, and she has leggings that are black and high waisted and cut off at her left leg and go down her right leg. Her lower legs and feet are currently unknown appearance wise.
