Cerdito Prospect Rift Crystals (CP10)
Notes specific to this specimen: Both smokey quartz and amethyst crowded on the front face. Beautiful fracture infills showing on both sides. Also has a nice amethyst-lined hollow on the back with amethyst veins all over. This piece has a flat bottom so it stands up and displays very nicely. Take a look at the cut bottom and you’ll see the very graphic splitting of the matrix and the subsequent infilling. Fantastic piece!

North American Rift (RIFT7)
Notes specific to this specimen: Beautiful white quartz infills the fractures of jet-black Rove Formation, with an edge vein of purple fluorite. Cut front face is polished while the back is natural but just as impressive. This specimen is a “stand-up” with a cut flat bottom allowing it to sit upright to show off the display face. Back is naturally rough.

Volcanic Bomb (EB12)
Notes specific to this specimen: Large, rare, combination fusiform bomb. This is the result of three individual magma projectiles running into each other in flight. In this case the merge of these three individuals was early in the ejection event but after the individual projectiles had started acquiring their own individual character. The combination of these three bombs resulted in one very large cigar-shaped bomb which acquired it’s own form which dominated the final shape before falling back to Earth.

Volcanic Bomb (EB14)
Notes specific to this specimen: Rare double bomb. These unique specimens form when two magma projectiles run into each other in flight before they completely harden. In this case the merge was early in the ejection event, before the two projectiles had started to acquire their own individual character. Instead the combination of the two was almost obliterated by the overall form taking shape before they fell back to Earth.

St Clair Flora – rare preservation (F9)
Notes specific to this specimen: Two sided specimen – front and back are equally compelling with a dense accumulation of ferns. Back side is colored yellow by iron intrusion making it a nice contrast to the classic white ferns on the front. There are multiple layers showing around the edges.

Dinosaur Bones (D1)
Notes specific to this specimen: This is a very well preserved neural arch and process of a cervical vertebrae, probably about midway down the neck of a hadrosaur (bipedal) dinosaur. The centrum is not present. The fine detail on the bone surface is exquisite and remarkably well preserved. This exceptional piece has no reconstruction.

Crystalized Clam (OK4)
Notes specific to this specimen: There are two clams here in this piece of matrix – one inside the other – creating a double hollow with great dogtooth calcite crystals replacing the inner clamshell and some crystals in the outer one as well. A unique and rare find.

Gunflint Chert (GIS21)
Notes specific to this specimen: One of the most colorful pieces so far – incredible piece! Multiple very clear stromatolite colonies throughout the specimen. All the more impressive because it’s from the world-famous Gunflint Iron Formation. This piece is from our original discovery in 2025. Beautiful deep red colonies, surrounded by pink and yellow and white with natural black halos. Unlike anything we’ve ever seen. Polished with brilliant shine on front face only. Back and edges are naturally rough.

Grypania Spiralis (GRY8)
Notes specific to this specimen: Nice slab showing several clear segments of Grypania, a couple with the classic full circles and others with curving arc formed by this species. A couple of the segments – like the circle in the lower middle – show examples of what’s been described as “desiccation” of the outer sheath along its length. This results in impingement of the sheath between individual cells, giving it a “bumpy” appearance. The desiccated segments are very rare.
