Despite hundreds of thousands of babies being born on a daily basis, each and every birth is a true miracle. However, no birth quite compares to that of twins, Isabella and Gabriella Shipley.

Upon looking at the twins, the first thing you notice is their piercing doe-eyes and cheeky smiles embedded into chubby cheeks. These features distract your attention away from the fact that the two baby girls, who may have shared a womb, do not share the same skin tone.

In fact, they look completely different races.

Gabriella was born with darker skin than her twin sister, which has prompted many to presume that the two aren’t biologically related. This is intensified by the fact that their older sister, two-year-old, Angelina, also has lighter skin.

When their mom, Clementine, began to share pictures of her adorable girls on Instagram in July, she was appalled by the barrage of ignorant messages she received.

“Nicknames like Ebony and Ivory would be perfect!!” wrote one user, while another typed: “Wow black and white twins.”

Clementine has been firm when responding to messages of this nature. “They’re African-American,” she writes to users who ask her what races the girls are, oblivious to the fact that they’re both of the same race. “Some people think they must be mixed but they are African-American,” she told Essence. “It really shows how amazing Black genes are since we can create such unique babies. ”

The two girls have attracted a lot of attention online for their unique story, which has attracted 15,600 followers to their Instagram page since July.

Despite their adorable curls and soft skin, Gabriella and Isabella have been victims of many cruel comments. However, their mother is confident that the positive outweighs the negative, and is therefore happy to keep sharing pictures of the cherubs.
