Do you have an interesting rock in your life?
Show me your rocks? Pebbles you picked up, cool granite counter, a pretty gem in jewelry, the stone facing on your building, a boulder you passed on the way to work, it’s all good.
Hai, new fren! That looks like a hearty rock, a perfect full handful to ground you in this place and moment, with enough texture variety to keep things interesting
Oooh, very neat! I’ve never been that close to baby rock; totally on my To Do list
Some crystals my son gave me with the gods of the watery underworld. (Oddly that’s the only rock-stuff I have on my desk.)pic.twitter.com/0KFDVzfXLF
You are rapidly improving my day. Here’s a shiny fren from outside the nearest building with my Earth Ring for scale. The blue-grey is labradorite (the sparklepants feldspar, kin to the pink or grey minerals in most granites). The black is probably hornblende.pic.twitter.com/OQqMv0yO9K
Just a shot of rocks from the beach, apparently not on my native Long Islandpic.twitter.com/aGBERMKav0
Oooh, high-energy beach to move pebbles that big! Bet the winter storms are spectacular
Meet “The Bunnet Stane” - a few miles along the road from my house! Does it count as a rock 
?pic.twitter.com/q4M3Z0Kvna
Absolutely, that is a gorgeous rocky fren! Totally photogenic. Give it a (very gentle) pet for me sometime? Looks like deliciously smooth sedimentary rock
my lil collection of rocks that my wife has gifted me over the years.pic.twitter.com/7WI2KCUiYl
Eee, she has good taste. I spy shiny fren ready to flash colours like a geologic butterfly, volcanic foam defying expectations of what it means to be a rock, and several that would be very soothing to pet
Frost-shattered rock, Atlas Cove, #HeardIsland; notebook for scale. It's probably basalt or trachybasalt, but Dr. @BeckyPaisley would know the geochemistry better than I.pic.twitter.com/UWUszoILb7
Ahhhh, always love the clean lines of a good frost-shatter when a rock is utterly fed up with cold

Same place, always wondered about this rock!pic.twitter.com/JW8GC2kUqT
Ooooh, looks soft & powdery. Maybe some type of weathered clay. Totally pettable
I thought this was was neat. I've no clue what's going on with the green spots though.pic.twitter.com/Dt0TSX2UUz
Spotty fren! Some kind of differential weathering. Maybe places where sea critters used to live & rotted the rock? Or inclusions of clasts/minerals in the rock that were more susceptible to weathering?
I knew I had a rock in here somewhere! This one is the Rock With Wingspic.twitter.com/SvFsiqE1UF
Ooooooh, a spine of rocks tough and resistant and standing fierce in the face of eons grinding everything else into dust & sand
Living room basket. Not pictured - rock in front of each child's school pick. Rock & birch bark from the yoop.pic.twitter.com/72jlP4XZY4
I love the idea that each kid gets to pick out a rock. Do they get to swap out their picks, or is it rocks they picked elsewhere & brought home
Silver Reef sandstone from Utah. The only place silver has been commercially mined from sedimentary rocks. The silver attaches to the chunks of fossil wood in the sandstone.pic.twitter.com/8k1yTOowZs

Gorgeous! Geodes are totally geology’s answer to tree rings
And my favorite thing that became a rock, fossilized ammonite.pic.twitter.com/iuliC08Dbq
