Pop one of these roughly 1-1/4" dia stones into the toe of a sock, smash it with a hammer, and be the first person ever to see your real-as-Nature-makes-it geode!! Ninety percent of them have the familiar beautiful white crystals inside. Formed by volcanic action, they are found all over the world, but ours are from Mexico. There is no way to tell from the outside if they have crystal centers, but we will send you two just to raise your odds, and we haven't had a dud yet in our stores!! Much much more fun and satisfaction than buying one already cracked.

Our best and prettiest-ever slices of polished agate, showing concentric rings of natural and dyed colors. The slices range from 3" to 4-1/2" across and from 1/8" to 3/16" thick. We've seen samples from milky white to blue, purple, red, yellow and brown. No two alike, by definition. We'll choose. Think scientific specimens, framed art, coasters, trivets, paperweights, or skipping stones for rich kids who don't want to search the beach for flat stones.

Just the one, actually, but it’s been sliced in half so the pair is perfectly symmetrical and mighty pretty. Although ammonites have been extinct for 65,000,000 years, we’ve got their approx 1” dia fossils for you. Our each is a book-matched pair of polished ammonites fossils of a single critter halved and polished to a bright symmetrical shininess. The colors vary from light tan to dark brown and we’ll pick because we have impeccable ammonitical color-shade taste. And yes, they’re just screaming to become cuff-links or earrings.

About 30-40 highly polished stones, all shiny, translucent, or brightly colored, ranging from 3/4" long to 1/8" long. Great for mosaics, jewelry, or aquariums.

These (7) small gemstones--quartz crystal, amethyst, tiger’s eye, sodalite, aventurine, orange calcite and jasper--are approx 1/2” to 1” and will serve as either geologic specimens, jewelry-making supplies, or help in restoring your harmonious flow of energy depending on how you roll and what you’re into.

These pretty, and pretty small, polished semiprecious stones include sodalite, tiger eye, quartz crystal, aventurine, amethyst, red jasper, fluorite, and rose quartz, plus a bonus assortment. You’ll get approx 1/2 oz of each in small corked bottles, 7/8” dia x 1-1/2” tall. The semiprecious pebbles are roughly 1/8” to 3/8” long.

Rock hammer with one squared chipping face and one pointy picking face, ideal for prospectors, rock hounds, construction and more. A single piece of forged and polished steel with a molded rubber grip makes this a solid and reliable tool that will last. 10-1/2" long x 6-1/2" across the 20 oz. head, 1-3/4 lbs. total. Well made. Good buy. Good bye!

The “I Dig It! Fossils” kit was the Oppenheim Toy Portfolio’s Platinum Award winner in 2018, and we think it's still a winner because fossils are really old anyway, and never go out of style. Unlike all the u-dig-’em-up fossil kits out there, this one features real fossils, in multiples. A color manual includes intros to fossils and paleontology, with instructions on making a grid and working slowly with the included metal-tip chisel, weighted hammer/pick and sponge. Fossils include snails and snail aggregate, stony coral, shark teeth and pre-amber resin. From Thames & Kosmos® and for ages 7+, especially those interested in how the pros do it.

Keep your magnetic hematite. Keep it tight! And keep it close because word on the street is, it has potential healing powers, or at least the ability to possibly-maybe boost your mood. At the very least, the specimens we have are great for the fridge or the side of a file cabinet. They have a super-stylish and refined shiny-pewter look, and they’re each about 3/4" to 7/8" x 1/2" thick. Plus, they look super-cool in bunches. Takes about (25) of them to weigh 1 lb, and you’ll get a dozen per order. Never hurts to have some nice, small reliable magnets hanging around--especially these, which won’t lose their pull in your lifetime.

From Brazil, rescued from the guts of quartz crystal antennae, these clear rock crystals are pebble sized (some maybe 3/8" long, most smaller). We're thinking classrooms and microscopes, small jewelry items, or, at these prices, a nice little bowl of crystals for the table. Each small box contains approx 2-1/4 oz of crystals. We'll send you (2) boxes, which will about fill a test tube if combined.
