Are there still gem tournaments?

A number of years ago, Matcherino would host tournaments where the organizers would give gems as prizes for winning. I'm not really sure how that structure worked, but I assume there was some partnership with Wizards since they were able to give codes for gems. However, I haven't seen (or heard) about anyone doing that for a long time. Currently, all the tournaments on Matcherino just offer cash prizes.

Are gem tournaments still a thing (on Matcherino or elsewhere)? Thanks.
