Adrian Chivu (b. January 2000), known professionally as 10 Diamonds is a Romanian musician, rapper, songwriter, and record producer raised in Năvodari.

He began his music career in 2015 being a producer for the underground collective Undercover Records under the name of Salty for over a year (he also worked under other past aliases like King Salty and A D D I E as a producer and King Addie as a vocalist).

After the group disbanded, he went on to produce for some of the local known names like Macanache and even internationally for Lil B.

He founded his own indie collective (soon to be label) back in 2019 called The Lonely Hearts consisting of him and his graphic designer / best friend Toni Toader for the time being.

He obtained his last and definitive artistic alias by morphing his appreciation for Marina and the Diamonds and the number 10 which is symbolically the captain in Romanian soccer.
