As of this round of the #mincup24 vote, I chose #Dioptase over #Wavellite since I own more specimens (obviously, I bought more because I loved it more, for the emerald color and its variety of localities). :blobcatgooglytrash:

#MinCup24 wavellite vs dioptase

Hmmm. Two minerals I've never actually collected. Nice wavellite occurs in a few places in southern British Isles: Cornwall, Devon, Wales, and southern Ireland especially. Here's some gorgeous Welsh wavellite, from the great mineralogy of Wales web resource put together by my pals at the mineralogy department of National Museum of Wales, completely closed by management this spring. 🤬 😭 I'm voting wavellite for them. #Cymru #Wales #Wavellite @MineralCup

Screenshot of a webpage from the great Mineralogy of Wales site, put together by Tom Cottrell, Jana Horak, Richard Bevins and others working at National Museum of Wales beftroe the mineralogy dpeartment was shut down. The page shows pictures of some beautiful pictures of wavellite from Wales.

O no what a match-up. Alas for #wavellite, lovely kiwi mineral, arbitrary choice to vote for the one in my collection has me voting for #dioptase. (I think this might be the furthest in dioptase has gotten in the years I've been playing! 👀 ... now watch I just jinxed it. 😆) #MinCup24

R3M2: versus

Wavellite is the kiwi of the mineral world, a rare phosphate mineral with a charming appearance.

Dioptase’s exotic desert beauty and rich emerald green are always ready for their close-up.

Which green will you choose?

Congratulations ! Your soft translucent green and your radial shapes have us seeing starbursts. Farewell to , the ancient mineral that condenses from solar nebulae, will be back.

A) that's SO close right now; #wavellite in the lead by 3 votes. B) I perhaps shouldn't vote at 5am but also when am I not tired anymore?? ("Hmmm wavellite looks like a weird kiwi.... I like that." 😅🤣🤣🤣) #MinCup24

is a more unusual gemstone, a soft translucent green mineral. The crystals form as bubbly crusts, precipitating in watery cracks, and even as stalactites. Its radiating spheres can form fascinating starbursts or cats-eyes when the glittery clusters are broken open. It, too, can fluoresce under UV light. The intensity of green is related to the trace vanadium within the crystals, varying from emerald or lime green all the way to white or even colourless.

For #MinCup24 (hosted by @MineralCup) today we see #Durangite competing against #Wavellite... I'm going with #TeamDurangite on that one, mainly because of the incredible reddish hues of the crystal. And the arsenic. And the pleochroism.

What do you think?

Vote here! mineralcup.org/2024/vote/r1m04

PS: looks like tomorrow's bracket will see a really special entry, the #Whewellite... Probably won't vote for that one...

Interesting match up - they're both classed as phosphates/arsenates/vanadates, one hydrous phosphate ( #wavellite), one anhydrous arsenate ( #durangite); both have fun crystal habit (when they accrue that far); both seem to be rare...

But wavellite has the more interesting chemical structure, and also I'm surprised it doesn't have arsenic OR something nastier, given the crystal structure mindat shows it likes... before it MAYBE goes all clusters of blobs. (I'd usually say botryoidal but mindat says the inside structure is still very sprays of crystal which is cooooooool but not very botryoid-formation.)

I think it's obvious how I'm voting, don't you? Lol. #MinCup24

Round 1 Match 4:

It’s a battle of exotic beauties for translucent green vs fiery ! Both are striking, unusual, and rare.

#Wavellite

Interesting facts:

• forms as a groundwater precipitate in aluminous or ferruginous #sedimentary #rocks, a product of low-grade #metamorphism of such rocks or in hydrothermal veins.

#crystal that forms in radiating circles. This mineral is easily recognized by its radiating clusters of #crystals forming circles.
