On 17 September 2010, Gravenberch made his U-17 debut in another encounter with Italy during the Ursapharm-Vier-Nationen-Turnier in Germany. The following year, he was selected by Albert Stuivenberg to play in the 2012 UEFA European Under-17 Championship, where he helped the Netherlands to their second consecutive title, defeating Germany in the final 5–4 on penalties, after extra time following a 1–1 deadlock. Gravenberch was also selected for the 2011 FIFA U-17 World Cup in Mexico where he scored his first goal in the second group stage match against North Korea. He appeared in all three group stage matches, of which they managed one victory, a draw and a loss resulting in an early exit from the tournament for the Dutch.
