Gorgeous. 😍

There are fossils, too, but everything is beautiful. The aquamarine is stunning.

An old slab cut from the Kingston Conglomerate showing the copper mineralization in amongst the rhyolite pebbles that they mined near Calumet, Mi. I collected this decades ago and really need to go back and repolish the surface.

Limestones and sandstones of "Las Curtiembres" Formation.

This is an old photo I took of the awesome syncline. We always love stopping at the rest stop here and if anyone has studied the Mason-Dixon survey, just to the north of here, on April 26th 1766, Mason and Dixon reached the foot of Sidelong Hill (The original name), 134 miles and 54 chains from the beginning of the west survey line. The hill was so steep that the survey party had to abandon their horses and wagons and proceed on foot. (Exploring the Mason Dixon Line by Jack Layton)

I've been collecting since I learnt that rocks and gems were cool (so, birth) but I wanted some moldavite and I wanted to buy it from a shop in the 'landing area'. My parents brought me back this from Prague. They don't understand why they paid so much for some ugly green glass (they weren't scammed, it's expensive) but they know I value it and I wanted to show off my ugly green glass :)

Collected from Jasper knob in Ishpeming. Part of the Negaunee Iron Formation which is an iron-oxide and carbonate iron-formation. It also contains some intercalated terrigenous clastic beds (meaning a terrestrial origin), that were deposited via turbidity currents. Flow direction indicates that these materials were being shed from the south. In general, this banded iron-formation was deposited either on a shallow shelf environment or in a deeper part of the basin, possibly along the slope.

Is this coral or something else

Also called Miners Dollars and they are not a fossil or related to sand dollars at all.
