If you break up Sugilite and Sardonyx into all of their components, they're made of Amethyst, Ruby and Sapphire or Pearl, Ruby and Sapphire respectively. Amethyst and Ruby are both hot-tempered and Sapphire and Pearl both aren't, in general. That might be why Sugilite has such a temper, because that's two hot-tempered component gems, and why Sardonyx doesn't, because that's two generally cool-headed gems.
perhaps, i do remember speculation about that a few years back! it’s definitely possible to write a sugilite with a temper who still isn’t villainized/portrayed negatively though since that just reeks of antiblackness. tbh i’d love to see a character in the show that has a temper but isn’t treated like a joke or portrayed negatively for it
