#that's a rock fact

Back on my bullshit looking up horse facts! Those of you who know me probably already know that I base Gan's steed on a Fresian, and my lovely follower @ultimatefangirl-exe pointed out the silver gene in bays and chestnuts -- but did you know black steeds with red manes are often that way due to sun bleaching?

Dark horses bleach in intensely sunny climates and salinity (both common in an arid desert). On its own it isn't bad, but if it doesn't shed and regrow can cause skin damage, sun burns, and even hair loss. If managed and conditioned properly, though, it can result in very pretty coats -- the ones above are referred to sometimes as 'firetail fresians' (the bleaching starts in the mane and travels to the coat over time, iirc).

I imagine Gerudo horses with these traits are a mix of both silvers and natural bleaching, but Gan's stallion remaining deep black while his hair is bright orange implies that his horse, at least, is pretty well conditioned against the sun.

Yes, this is really cool. And here are some fun facts about these stones from a geologist to keep in mind! These apply to both people looking at these for themselves as well as artist and writers.

If you are using any of these gemstones in jewelry you need to keep the hardness in mind. Fluorite is very beautiful but it has a hardness of 4. You do not want it on rings, bracelets, or long necklaces. Any jewelry where it may bump up against things is a no-go because it will get scratched and any cut edges will be ground down. For reference, glass has a hardness of 5.5. Fluorite would still be fine for earrings, chokers, or crowns. It is also often fluorescent!

Several of these have been treated in some way. Anything with "mystic" in the name has been coated to get that effect. Most sapphires are heat-treated to get that deep blue color. Most citrine is treated as well to get that color as natural citrine is relatively rare.

Labradorite can have many colors, but it's not going to be pretty at every angle. These pictures are taken at the perfect angle where you can see the brilliance of the labradorescence. It'll be this grey-blue to grey-green rock that flashes blue or yellow at the right angle.

SOME OF THESE ROCKS ARE POISONOUS!!!

This is one thing that I really want to stress. Wulfenite is my favorite mineral. It is full of lead. Please for the love of whatever god you may or may not believe in, do not put that against your skin.

Some of these are dyed. The purple agate and jasper are dyed. For agates, if they're monochromatic and something bright like purple or blue, that's dyed. Howlite that is not white is dyed. Howlite is commonly dyed turquoise for use in costume jewelry.

Inclusions, such as rutile, can be really beautiful but are also technically an imperfection in the stone. It can be a weak point where the gemstone may break in the future. That's just because it is literally one gemstone inside of another.

The ways you can cut and mount these depend on different properties of the gems. Some minerals, like labradorite, are opaque. Cleavage planes can affect where a stone can be cut as it can cause breakage in the gemstone.

A lot of these are varieties of a different mineral species. Amethyst, citrine, and smokey quartz are all varieties of quartz. Agates are also just a microcrystalline variety of quartz. Beryl has a lot of gemstone varieties such as aquamarine, emerald, morganite, goshenite, and heliodor. (Note: chrysoberly is not a variety of beryl. It's a completely separate mineral)

Diamonds are more common than you think.

Pearls are classified as gemstones for gemological purposes but they are geologically not rocks. They're organic and made by oysters.

Hope this information is helpful to some people. There's a lot more to rocks than most people think.

"I think it's sweet," Steve says.

Robin wrinkles her nose. "Nothing about Eddie Munson is sweet. He's a sewer rat, at best. Or like twenty opossums in a trench coat."

"Opossums are cute."

"He probably has rabies."

"You say that about me all the time, so I guess that's good. We'll have rabies together."

"He gave you a rock."

"You give me rocks all the time," Steve says, rolling his eyes. He runs his thumb along the textured edge of the rock Eddie'd handed to him.

"Yeah, good rocks." Robin scoffs. "That one sucks."

Today’s Exhibit of the Day? It’s one of the largest amethyst geodes in the world! At about 13 ft (4 m) tall and 9,000 lbs (4,082 kg), this giant weighs about as much as three compact cars. It was born when molten magma poured from the Earth’s crust some 135 million years ago. While its dazzling purple crystals might catch your eye, this geode would have originally been composed of colorless quartz—its distinctive amethyst color deriving from millenia of natural radiation, heat, and trace contaminants. 

You can spot this geode, and other sparkly specimens, in the Museum’s Mignone Halls of Gems and Minerals. We're open daily from 10 am-5:30 pm! Plan your visit.
