Partial black Megalodon fossil tooth, 2.5 inches long by 1.75 inches wide. The jet black coloration happened over millions of years as iron sulfide replaced the original tooth material during fossilization. This is a partial tooth fragment, not a complete...

Namibian quartz cluster from the Streep Mine, 1.5 by 1 inch. The Streep Mine in Namibia produces quartz with exceptional clarity and well-developed crystal terminations that collectors seek out specifically. Multiple terminations rise from a shared matrix base in water-clear...

Polished Brazilian quartz points with chlorite inclusions, available in four options. The green chlorite inside each point formed as a phantom layer on the growing crystal surface, was encased as the crystal continued growing, and is now permanently visible inside....

1 inch shungite heart carved from genuine Russian shungite. Shungite is a carbon-rich mineral from the Karelia region of Russia, approximately 2 billion years old, making it one of the oldest carbon-bearing minerals on earth. Deep black, smooth matte surface...

Single clear quartz tumble stone, approximately 1 inch, with natural internal inclusions, wisps, and milky sections. No two quartz tumbles are identical. The inclusions inside each stone are trapped minerals, gas bubbles, or other formations that developed during the crystal's...

Large labradorite freeform weighing 620 grams, 3.85 inches tall and 3.5 inches wide. From the outside this looks like a plain grey-green stone. Rotate it under light and shifting blue, green, and gold color flashes appear that were completely invisible...

Labradorite freeform weighing 390 grams, 3.5 inches high and 2.5 inches wide. Plain grey from straight on. Tilt it and a blue or gold flash appears. That shift happens every time the light around it changes, which is exactly what...

Polished baryte and natural marcasite slab from the Lubin Mine, Lower Silesia, Poland, 4 by 1.25 inches. Baryte is one of the heaviest non-metallic minerals and you notice it the moment you pick this up. The slab has two distinct...

Raw ruby crystal from India with record keeper markings, 30mm by 12mm in a natural hexagonal form. Ruby is the red variety of corundum and the chromium responsible for the color also makes it fluoresce vivid red under UV light....

Polished kyanite and quartz stone, 1.75 inches long and 0.40 inches wide in an oval shape. Blue kyanite blades are visible within a matrix of clear quartz, two minerals that formed together during the same metamorphic event. The contrast between...

Prophecy stone, approximately 1 inch by 0.5 inches. This is a pseudomorph: pyrite or marcasite originally grew in a geometric crystal form. Over time the original iron sulfide was chemically altered to limonite and hematite while the original crystal shape...

Calcite Mercenaria clam fossil from Ruck's Pit, Fort Drum, Florida. These are Pleistocene-era hard clams where the original shell material dissolved and was replaced by amber-colored calcite crystals over millions of years. The result is a shell-shaped mass of amber...
