Check out these thomsonite balls from Madhya Pradesh, India! They’re like tiny, vibrant orange puffballs, bursting with delicate, hair-like mesolite strands growing on top. Pure nature’s artwork! 😲 Have you ever found a rock that looks this wild?

Bluish gray sphere of thomsonite-Ca in a cavity in basalt. The sphere is composed of flat tipped thomsonite-Ca crystals. The flat tips distinguish it from cowlesite which also occurs here

For #ThingThursday, this silver & thomsonite necklace that belonged to my mom. She & my dad purchased it from the Thomsonite Inn jewelry shop back in the early 1990s. Designed/made by Tania Feigal (her obit: www.oklahoman.com/story/news/2... ).

More on Thomsonite:
www.thomsonite.com/thomsonite
Silver oval flat disc with a pattern on the edges (resembles eyelashes IMHO) and then a seed-like design on top of it with a couple of curls of silver and a round ball at the top and a leaf like design coming off of it, the green & gred thomsonite is set in it to look like the main part of a seed I think. Another angle of the same necklace. My pictures aren't the best.

Thomsonite is an all-time MN classic! ✨ It's a rare zeolite mineral that (like most cool rocks) is the product of volcanic activity. 🌋 This variety started to form over 600 million years ago and can only be found on a limited stretch of the Lake Superior shoreline. 🌊 #mineralogy #geology #thomsonite

For #MineralMonday, the vanishingly rare and delightfully named* clinojimthomsponite. A very weird triple-chain silicate from Achmelvich, Sutherland.

*named for James Thompson, but there was already a thomsonite, so they called it jimthompsonite, and this is the monoclinic polymorph
Some small prismatic crystals displaying bright birefringence colours against a black background. They are smaller than the 0.5 millimetre scale bar.

A cavity in basalt that is lined with bluish gray thomsonite-Ca. The fractured spheres around the rim show the internal structure. The protuberances on the surface of the thomsonite are also thomsonite-Ca

Today's ROTD is Thomsonite with Heulandite. Both minerals are members of the zeolite group, and are hydrated sodium calcium aluminum silicates.
The radiating patterns of crystals are unusual and beautiful.
Found these at Oracle Natual Science in KC, MO.

Highly recommend that shop!
Thomsonite and Heulandite. Thomsonite is the grey clusters, and the heulamdite is the radial crystal formations. Close up of the radial Heulandite crystals on the Thomsonite Copper inclusions in the substrate provide the green coloring and this highlights the wild radial Heulandite explosions. This highlights how pretty the Thomsonite is, and has some excellent radial Heulandite growth with druzy pockets.

Please do not break in and steal this necklace made of silver & thomsonite as it is important to me but hey, I should show this stuff off sometime somehow. (I need to clear out my house so I can make it into a museum, obviously.) (Very limited hours.)

Outstanding article (from 2019) about Thomsonite:

https://www.rockngem.com/radiant-minnesota-thomsonite/

I find it difficult at times to describe this gem & how cool & rare it is.

Spent hundreds of hours in my youth on the shores of Lake Superior searching for this rock.
Radiant Minnesota Thomsonite | Rock & Gem Magazine
The rarity of thomsonite (also known as lintonite), Minnesota's version of the zeolite mineral, is due to the fact that this gem variety is only found on a six-mile stretch of “North Shore” beach.
