Diakite enrolled at Blue Ridge School in early 2014.
[6] When he first came to the United States, he could only speak French, and Guinean former basketball player Mamadi Diane was among those who helped him acclimate.
[4] Diakite played two basketball seasons at Blue Ridge School and also earned
varsity letters in
track and field and soccer, because the school required students to play a sport each season.
[1][7] As a senior in basketball, he averaged 12 points, eight rebounds, and four blocks per game while leading his team to the Virginia Independent Schools Athletic Association (VISAA) Division II state title and a Virginia Independent Conference (VIC) championship. Diakite was named second-team All-VIC in soccer in 2014–15, and he won back-to-back VIC
high jump titles.
[1] In basketball, he was a consensus four-star
recruit and the top prospect in the state of Virginia. On August 4, 2015, Diakite committed to play for
Virginia, turning down offers from several other
NCAA Division I programs, including
Baylor,
USC, and
Washington.
