Alexandrite is massive in size with six arms and a curvy body. Her skin is a deep magenta color, and she has an unknown number of eyes, a pointy nose, and full lips. Her hair is super thick and messy, being a solid bright mint green color. Her top pair of arms come from her shoulders, while the next two sets are below, and they’re each long and skinny. Her gemstones are on her forehead, chest, and in the palms of her upper left and right hands and are burgundy, mint green, and purple.

Alexandrite starts off cold, somewhat distant, intense, and sloppy. During "Fusion Cuisine", she is shown not to have a distinct personality, instead she displays the three separate personalities of Pearl, Amethyst, and Garnet. These personalities can exist at the same time and often come into conflict with each other, which may cause Alexandrite to de-fuse. Also, they typically become more prominent as the fusion becomes more unstable, showing Pearl's fear of food, Amethyst's hunger and argumentative personality, and Garnet's social awkwardness, leadership, and control of situations
Alexandrite possesses standard Gem abilities, bubbling, shapeshifting, fusion, regeneration, agelessness, and superhuman strength/durability.
Alexandrite has incredible amounts of physical strength and stamina; her long legs allows her to cover a lot of ground quickly. She uses her sheer strength and size to lift weighted objects, like a bus. Garnet describes her as "an incredible force on the battlefield", making clear Alexandrite is indeed a formidable warrior, capable of anything as long she keeps a singular goal in mind.
