Is there a tungsten carbide-tipped engraving/writing pen and a magnetic pendulum in the same tool?
If so, where can I buy one?

I remember seeing one, or am I delusional?

No words needed 😌

A little piece of garnet

Hmm..

This is my most recent chert sample I got from San Luis Obispo. :)

Chert

A few days ago I was at the Mountain Taberg in Småland (Southern Sweden). It fully consist of Titanomagnetiteolivinite and is the only occurrence on Earth, except a small one in New Jersey.
The rock has a iron content of ca. 30 %, the processed iron has traces of Ti and V, thus the steel is hard and tenacious.

Taberg, a unique Mountain

I hope everyone's safe in Venezuela after the double quakes last night. 

There's been a lot of activity in many regions around the world lately. Earthquakes, waking volcanoes. Typhoons... Even some mountains starting to crumble in big chunks.

Stay alert, stay safe. Don't ignore the warning signs.

Shaky ground!

Two rocks are talking. 
One says  “I feel so pressured lately"
The other replies “Don’t worry, that’s just metamorphosis! you’re becoming your best self"

Pressured

Within my geography lecture, all of these were brought out. I found the one closest and in centre to be extremely pretty, of which it is actually a fossil of a sea urchin.

Fossils and rocks

I got this cool Kyanite sample

**UPDATE* Since posting this, i have settled on this stone being green zebra jasper. Still nothing on where it may have come from, though.*

I've had this thing for a several years. I found it buried in a yard in south-central Kansas, USA. It's been slowly smoothed and given the slightly glossy look by keeping it in my pocket with my wallet and handling it over the course of 13-16 years.

It can scratch a glass mason jar, but I'm unsure if it can scratch anything harder than that.
It's 34mm × 19mm × 19mm and weighs 14.7g. *for a better idea of size*

I know of some minerals that look somewhat similar, like green zebra jasper, but I am ambivalent otherwise.

Please help me identify this

Anyone like columnar basalt? It's my favorite rock unfortunately I don't know if Alabama has any

Y'all addicted to rock??? Me too.

As a fan of #geology and LGBT I really enjoy this #meme

The picture can't giving back it's starry shine, mined in Morocco and it's common. The good quality ones and the geodes are rare and usually small, the tabled crystal form is the most prized. A piece of the Starry Sky, crafted by Mother Earth.

Gift from the Copper mine: Azurite

Also, what did the emrald say to the graphite? You rock!

I've had a weird obsession with Obsidian since I saw that one guys on YouTube make spears and arrowheads out of Obsidian with... Obsidian.

Honorary mention to Amber, it's not a rock but it's so effing cool.

What's your favourite rock and why?

Sandstone. Weathered. Fine to coarse grain.

1st time we found this site, we thought it's limestone 😅 took a closer look and found out it's sandstone. It was a mine. Weathering make this site look like this. Locals call this site 'Jurassic Park' because of the landscape reminds them of Jurassic Park film. Worth to visit 😁✌🏻

It wasn’t their fault, there was just too much friction between them.


I saw it. I had to share it, so here it is. Sue me.

Why did the tectonic plates break up?

That lava flow frozen in time...

Calcite var. Hungary- Pilisjászfalu, collected by Zoltán Urbán in 2019, bought it, and added to my collection in the same year. It begun to dissolve back, that's why it's dull surface, Mt. Pilis is famous here from it's karst cave system, it's stalactites mainly from this calcite.

Collection

It is from my collection, and it kept all the time in that plastic container due the alpha radiation. It's used worldwide as dense uranium, pressed into yellowish "cakes". Mined in 2021, France. It can be found within other copper ores.

Rare gems: Torbernite

Something really common, but really beautiful. It's the most frequently mined ore (galena) in the Carpathians along with the iron, copper and aluminum ores. This specimen is probably from Romania or Slovakia (I haven't got a label, but it's price said that). Not my rarest, but one of the best specimen in my collection.

Quartz-Pyrite-Galena on matrix

This one is Spessartine Garnet with Quartz and some metamorph crystals from China. The Garnets are widely used since the Bronze age as abrasives and jewelry and  it's color varies from the burgundy and tea color to green and even blue (which is very rare).

Rare gems: Garnet (it's not that rare at all, but still precious)

Noble beryl from Shigar valley, Pakistan.

Rare gems: Aquamarine

I posted this azurite a while ago, so I'm not going to do a bigger description about it, but now I can show  it's real beauty thanks to the video posting.

Azurite repost

Actually an abundant rock forming stone, coming along with marble. It's color depends on the iron content. Sometimes the well formed crystals used as gemstones, which is very rare. This one mined in Italy.

Looking for a long term relationship

Today I was in one place in East Africa in Tanzania where the main purpose was to enjoy local geology due to the existence of many consequences of volcanic activities such as Mount Kilimanjaro It was really interesting
