"We want to continue to use our platform and the opportunity to shoutout a very special member of the basketball community -- Brittney Griner's birthday is today," Curry said before the Warriors hung their fourth banner in eight years.

"She's 32 years old. We want to continue to let her name be known. And, we pray that ... it's been 243 days since she's been wrongfully incarcerated in Russia. We hope that she comes home soon and everybody's doing their part to get her home."

Griner, who's been in custody in Russia since February, briefly thanked her supporters during what should have been a special day ... saying in a statement, "Thank you everyone for fighting so hard to get me home."

"All the support and love are definitely helping me."

As for the Warriors, their rings (made by Jason of Beverly Hills) are incredible -- they feature 16 carats of yellow and white diamonds set in yellow gold to represent their 16 wins in the playoffs.

It's the first championship ring to be made up of mostly yellow diamonds -- in honor of the team's "golden age."

They also have a special secret compartment ... which reveals the number of trophies each player has individually won over the course of their career.

There are seven carats of yellow cushion cut diamonds on the bezel to mark the team's total championships in franchise history ... and 43 baguettes in the bridge of the logo on top for Curry's 43-point performance in the Finals.
