abyssal crown 3d model

3D Roblox-style head accessory crown called the Abyssal Crown. The crown is wide and low profile, designed to sit comfortably on a Roblox avatar's head. The base of the crown is made of dark jagged deep sea rock, almost black with dark navy blue tones. Growing out of the crown are tall bioluminescent coral branches in cyan and teal, glowing softly. Two small jellyfish sit on the left and right sides of the crown with their tentacles draping elegantly downward past the crown base. The center features a single tall dark crystal with a faint glowing teal light inside it. Scattered glowing dots and particles float around the crown like deep sea bioluminescence. Color palette: deep navy black base, cyan and teal glowing accents, purple hints on the jellyfish. Style: Roblox friendly, slightly low poly but detailed, stylized not realistic. Render on a dark background with studio lighting to highlight the glowing elements.
