CARAT (캐럿) means "carat" — the unit of diamond purity. Just as SEVENTEEN shines like a diamond with 13 members across 3 units, CARTs measure the purity of that light. Also a wordplay: 13 members + 3 units = SEVENTEEN, and fans are the "carats" that make the diamond shine.
Who Are CARAT?
CARats are one of K-pop's most generous and organized fandoms. They are known for funding large-scale fan projects — including a SEVENTEEN star named after the group. CARats set world records for album purchases in 2023 when FML sold 4 million first-week copies. They're also known for their emotional "Ode to You" concert tradition, where each member reads a letter to CARats during every world tour.
A diamond-shaped lightstick — because CARats and diamonds go together. The Carat Bong glows in a cyan-blue color and syncs via Bluetooth for concert effects. The third-generation Carat Bong has a rotating inner diamond design.
