How do you get the Season Year 2024 - Diamond Icon?
It was a ranked reward. Riot's description in the client reads: “This icon was earned by achieving Diamond in Season Year 2024.”
Is the Season Year 2024 - Diamond Icon still available?
No. The Season Year 2024 - Diamond Icon was a ranked reward. To earn it, you had to reach Diamond during Season 14 (2024). Riot does not hand out past ranked rewards again, so you cannot earn this icon anymore.
