The team unveiled giant rings after winning its record 18th championship against the Dallas Mavericks in the NBA Finals in June. The rings are set with 15 carats of white diamonds and represent the 15 teams in the Eastern Conference. This is exactly where the symbolism begins.

The ring, made by Jason of Beverley Hills, also features a removable top that reveals a tiny replica of the championship banner that the Celtics raised before hosting the Knicks in the season opener on Tuesday night. On the inside of the removable lid is a small, circular piece of the actual hardwood floor where Boston won the title.

Each ring is also individually designed and features a nameplate on one side with the player’s jersey number filled in with diamonds.
