Blue Diamond 💙 🔷️

Blue Diamond is a tall, slender, and elegant Gem with long limbs and a graceful figure. Her skin is light blue with slightly violet undertones. She is enormous compared to humans and most Gems; her approximate height would be 19 meters, but being a Gem, she can change her size at will.
She has long, thick, straight, very pale blue, almost bluish-white hair that falls around her body to about the lower part of her torso. Her face is long and oval, with large, drooping, light blue eyes, prominent eyelashes, a small nose, and relatively full lips. Her eyebrows are thin and arched.
Her neck is long and slender, while her arms and legs are equally long and slender. In the center of her chest is her blue, diamond-shaped gem, embedded directly into her body.
Its overall appearance is elegant, delicate and stylized, with a predominantly vertical silhouette and colors ranging from light blue to dark blue tones.

Blue Diamond is a serene, melancholic, and deeply sensitive figure, although her position as a Diamond also allows her to appear authoritarian and distant.
She is a very emotional person, especially marked by pain and grief. She expresses her sadness through crying. It is common for her to appear sad, thoughtful, quiet, and withdrawn, even becoming completely absorbed by her memories and emotions.
Despite her immense power and authority, she has a compassionate and empathetic side. She is capable of genuinely caring for other Gems and/or people.
She can also be protective and affectionate with those she considers important. Her way of showing affection is usually quite calm and solemn, more through actions than through enthusiasm or exaggerated expressions.
One of her most important traits is that she tends to be ruled by her emotions. Her sadness can be so intense that it affects even those close to her.

They may also call her simply "Azul," although this nickname is only used by those close to her.

Blue Diamond is also super inexperienced about human behavior; she doesn't know about customs or anything related to humans. She doesn't know if something is considered shameful, bad, or normal among humans.

One fact to mention is that Blue Diamond is a Gem. Gems can shapeshift because their bodies are made of energy/light projected from their gem. They can modify that projection to adopt different appearances, sizes, or even shapes.
The transformation depends on their concentration and control of their own energy. However, maintaining a different form for too long can be exhausting, and if the Gem loses focus or sustains enough damage, it can revert to its original form.
