Mineral Cup 2023 is on!


And you thought September was all a about Fat Bear Week!

I just found out about this today while exploring Mastodon:

Do you like rocks? Are you an avid mineral collector and you’ve recently moved all your books from the shelves to make space for your best specimens? Do you like to look at the beauty of rare and precious minerals? Are you interested in mineral properties and how we use minerals in everyday life? Or are you just curious and want to learn more about minerals? Or maybe you have fond memories of a long-lost (but not forgotten!) childhood rock collection? Then Mineral Cup is for you!

What is Mineral Cup?

Vote for your favorite mineral each day in September for the annual Mineral Cup, a single-elimination tournament to determine which contender will be crowned Champion with bragging rights as the best mineral of the year. A total of 32 minerals are featured in the tournament: 15 of the previous year’s top contenders, a crowd-selected comeback champ returning after elimination in previous years, and 16 new minerals (including ones that you nominate!). Learn more about minerals, cast your votes, recruit friends and allies to join the game, and campaign for your favorite minerals!

Here is today’s match:

  3. This isn’t a formal geological poll, of course. It has spawned a lot of beautiful images, though, on Mastodon and probably Twitter.

    And, hey, now you know not to touch that brown jenga rock!
