I think purple fluorite and opal are pretty together

Mineral Swag Tournament Finals

Okay y'all, this is it. The FINAL for the Mineral Swag Tournament.

Fluorite.

Fluorite is a fantastic mineral. It would not have gotten this far otherwise. It comes in a ton of colors, it naturally forms both octahedra and cubes (and massive deposits), and it show brilliant bright blue color under UV light. Fluorescence (the phenomena) is named that because of fluorite!

It also does this fun thing (that other minerals do as well, but it is common among fluorite) where it changes color as it forms because of changing impurities in the solution from which it grows! Elements like iron, copper, manganese, chromium (and more!) can replace individual ions in fluorite's chemical structure and cause the light to reflect different wavelengths and we therefore see that as a different color. This can also happen if a fluorite ion is missing because the sample has been irradiated (for example) and NOTHING replaces it and so the light still reflects in a different way! That is one of the ways we get purple fluorite and this method of producing color is known as color centers.

Of course, not all fluorite fluoresces. Not all fluorite forms cubes or octahedra. Some fluorite is colorless. Some of it looks like an ugly little piece of translucent rock. Or a vein of purple mineral in a crack between two other rocks. It would be irresponsible for me to insinuate that all fluorite is this majestic.

But there are some properties that you will always find in fluorite. It has four directions of cleavage. It is the defining mineral for a 4 on the Mohs hardness scale. It will always be made of calcium and fluoride in a 1:2 ratio. These things are some of what define fluorite as a distinct mineral!

Opal.

Opal is a beautiful gemstone. Please note that I did not call it a "beautiful mineral" because it is not technically a mineral. It is a solid, inorganic substance with a defined chemical formula, but it lacks the specific crystal structure which minerals MUST have to be considered a mineral.

This crystal structure is the entire reason why fluorite is capable of forming cubes and octahedra. And why garnet forms dodecahedra and beryl forms columns and so on. Opal only comes in those fun little oval shaped stones because it was cut that way! Fluorite forms cubes because it just knows how. Otherwise, opal forms shapeless masses that fracture rather than cleave (fluorite cleaves--four ways). That being said, opal's lack of crystal structure allows it to sometimes be iridescent.

After all, there is a reason opal made it this far. When it shines, it is beautiful. There are several varieties of precious opal (opal that displays its trademark play-of-color/iridescence) and they are all very fun to look at. These precious opals are made of microscopic silica spheres that light reflects off of in weird ways and causes opal to look like it is glittering with a dozen different colors.

However, one would be remiss to forget common opal! Some opal is milky white or a translucent blue, and if you're going to love opal at her fire opal, you better also love her at her common opal.

Here are some raw pieces of opal (common opal on the left). Note how they break irregularly. They have conchoidal fracture, which both quartz and normal glass (all of which are just silica) also have. I personally think conchoidal fracture is pretty neat.

Also, while the opals on the right would still be considered precious opal, they are what the average person is likely to find. Just little bits of iridescence here and there.

And, like fluorite, while not all opals have all of the cool features, they do have some similarities. They will always have conchoidal fracture if they break. And they will always be made of hydrated SiO2.

...That's all I have for these guys, I think! I hope I have been as impartial (and accurate) as possible while presenting these, your FINAL mineral swag contestants. If you have any questions or anything, let me know. The Rock Swag Tournament will start shortly after this concludes! Submit your rocks here! And specific rock formations or named rock varieties here!

I love designing and drawing fusions. They are so cool. Anyway.

Expression practice I really liked

a small collection of my most recent houseki no kuni (land of the lustrous) designs i've made over the past few months. half were drawn on aggie ( imperial topaz <- bottom left and venus fluorite <- top right), while the other two were drawn on procreate (opal <- top left and grape agate <- bottom right ) . i've got about four more of these and an absolute motherfuckload of more designs i wanna make, but . yeah . more information on them below the cut

- opal , current moon gem. was formerly an expert on lunarians and history . was replaced by opalite <- not pictured . ( MOH 6 )

- venus fluorite , current earth gem , was a replacement for the short lived moonstone <- not pictured. does 50 / 50 in patrol duty and gem repair, when they are on patrol their partner is serpentine <- not pictured . ( MOH 4 )

- imperial topaz , a solo patrol gem . does not enjoy working with others because of their speed . occasional partner to grape agate . ( MOH 8 )

- grape agate , ( design maybe-maybe not final ) works in fashion . occasionally pairs up with imperial topaz for patrol if there's been an influx in sunspot sightings . ( MOH 7 )

reorganized the rock, mineral, and fossil shelf…. not all of my specimens fit on here (namely the Huge ones) but it looks nicer now !!!

baghera+mariana+charlie fusion would have the voice of an angel. a tall queen. slaying everyone in her path with sound waves as a weapon. explodes

ooooh i have to design baghera and figure out what red/orange, yellow, green and purple would make so i can make their fusion now

A pair of fan characters that I made for a Houseki no Kuni AU in a server that I'm in! The big joke is that the AU was so fun that I made these two before I even started watching the show.

WE HAVE A WINNER

Congratulations to the first ever Mineral Swag Tournament winner:

Fluorite!

By my calculation, Opal only lost by about 35 votes (of the 1460 total votes), so it was close!

And of course, we're getting ready for the Rock Swag Tournament! Submissions for rocks and specific rock formations are still open.

Submissions for the rock portion of the tournament will close Wednesday, July 12 around midnight!
