Not Steven universe, I just really like rocks.(and the show). If you’re not from America, a quarter is .955 of an inch. I would just round to an inch for comparison :)
A huge chunk of petrified wood from Arizona! The color is so unique, and the mass is something you wouldn’t expect! In the last picture, you can even tell how hard it was to hold up, if you look at the tendon popping out.
A geode I bought from the Howe Caverns gift shop! I love the stalatic structures. I had been looking for one that hadn’t crystallized with facets, but the cool bubbles :)
A tektite! It’s a glass formed when a meteorite flies to the earth at breakneck speed, and slam into the earth. It creates so much force all the rock around it melts instantaneously. The process creating tektites is somewhat like the making of obsidian, where it melts and cools very quickly, making a vitreous, glassy, black stone.
Benitoite and Neptunite! Benitoite is one of the worlds rarest minerals or gems, only found in a Californian mine! The value climbs in value, because the mine was closed in 2006. The name benitoite comes from the river located near where it was discovered, the San Benito River.
An opal necklace from my grandmother. The opal looks like it would be from Australia, and the blue stone is aquamarine. The clip holding the necklace on has white diamonds. Though I’m not sure if the opal is synthetic or not because of how perfect it looks, and because my grandma isn’t an expert on stones, I love it to bits.
The darker green is Malachite, and the light blue is Chrysocolla! This one is pretty big, but I don’t think I paid much. I don’t see any azurite on it, so I think it didn’t form in the vein it came from, which is odd, considering how often they are found together.
