The Diamond Unicorn is a legendary pet in Adopt Me! that was added on March 20, 2020, as a part of the Star Rewards update. It can be hatched out of a Diamond Egg. The Diamond Egg requires players to maintain a login streak of around 1 year and 3 months, or can be obtained through trading. The other two pets that can be obtained from the Diamond Egg are the Diamond Dragon and Diamond Griffin. When hatching the Diamond Egg players have 33.3% chance on obtaining the Diamond Unicorn.
The Diamond Unicorn is a recolor of the Unicorn. It has a diamond colored body, a golden horn and mane, and tail. Its colors are opposite to that of a pet from the Golden Egg. At night, the color changes and its body becomes a dark blue color while the mane and tail become a darker yellow.
The Neon version of the Diamond Unicorn glows bright yellow on its mane, horn, and tail. This version's color can be different in the day than it is at night.

The player was banned from Adopt Me!.
