Hyalophane (below) is a barium rich feldspar. I learned today it is a variety of microcline and not its own species. Also learned that labradorite isnt its own species either anymore and is a variery of anorthite. The IMA needs to calm down with changing all these feldspar taxonomies 🫩

Vitreous, semi transparent, colorless crystal of hyalophane feldspar held in my hand.

Did not know today was International Rock Day until a few hours ago (or that the day exists, tbh). And i work with the national collection 🫪

Today’s Exhibit of the Day? It’s one of the largest amethyst geodes in the world! It's about 13 ft (4 m) tall and 9,000 lbs (4,082 kg). It was "born" when molten magma poured from the Earth’s crust some 135 million years ago. Photo: D. Finnin/© AMNH

A photo of the Museum’s large amethyst geode on display in the Halls of Gems & Minerals. Its crystals are a striking purple color.

Bought a few samples of designer fragrances recently. Was expecting the Cartier fragrance to smell rich and luxurious but instead it smells like sweat and taco seasoning 💀

Can someone explain to me like im 5 how virginia's redistricting, which was democratically voted on, was declared unlawful but tennessee and florida's which were not voted on were completely fine.. ?

So i read about this new material that was recently fabricated, its polycrystalline silicon named Crysilliz. Wanted to buy some and the prices were reasonable but what in the hell are these shipping prices?! Tariffs i guess? Really disappointing

My checkout order of 1 crysilliz crystal for 26 euros and 54 euros for shipping
