Sandstone

Sandstone was one of White Diamond's most accomplished captains, leading his own enormous ship. His reputation within her court rivalled that of the lineage of Emeralds that Blue Diamond holds, yet even more impressive, he is just one gem. However, he's QUITE the handful and his attitude barely suits the court he was formed in. So, as a show of 'grace' (desperation), White Diamond gifted Sandstone personally to Blue Diamond. Which works out enormously in his favor, since he's been infatuated with her the moment he saw her.

Sandstone is the father of Desert and Zebra Jasper.
