Create your own crystal garden and you'll never again have to run out to the store in the middle of the night for more crystals. Put the approx (2) ounces of rocks from this kit in a bowl, add white vinegar, put it in a warm place, and wait for the vinegar to evaporate. You'll have crystals in (2) days to (2) weeks. Add food coloring if you want to change your tasteful monochromatic crystals into a phantasmagoric garden of color. You provide the bowl, vinegar, food coloring and warm place. For ages 8+ with adult supervision.

Don't panic. A meteorite is speeding toward you, but it will only hit your mailbox. These small hunks of genuine meteorites are approx 4,200 years old and have been harvested from Chaco, Argentina. (We never miss the meteorite harvest in Chaco.) Most will weigh 20-33 grams and measure approx 1-1/4" x 3/4" x 1/2", which is very dense. Carry one in your pocket and you'll never be hit by a large meteorite. (And if you are, we'll give you double your money back.)

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.

Crystals are for pointing toward you or away from you, depending on what you believe or want, or for polishing, or just for looking at. You get a 3-pack of quartz point crystals, approx 1" to 2-1/2" long, ready for psychic healing, jewelry, or plain old-fashioned lapidarian fascination. Your hunks of point crystal might have an actual point, might not: nature's like that.

It leaks like a sieve because it is a sieve. And a big'un at 13-1/4" top diameter with a reinforced stainless steel screen at 11" across on the bottom. Fits nicely on a 5 gallon bucket. CJ says it's for mineral panning or archaeological fieldwork, but some of us think it's from a lost 5-foot tall Mr. Coffee. With a mesh size of 1/20", we'd use it to pan for gold.

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.

Tektites, called glass rocks, are formed when meteorites from outer space crash into our home planet and, by Jupiter, no rock collection is complete without one! The driest of all rocks, tektites are black to olive-green, and average less than .005% water. These samples will be roughly 1/2" to 1-1/4", and you'll get (2) to (4) of them, depending upon their size.

You say you haven’t got time to wander beaches and woods in search of interesting rocks to tumble? We feel your pain. Order up this rock-tumbler refill kit, and you’ll get approx a pound of assorted quartz, hematite and agate pieces (we got 30+ in our sample bag) without leaving your couch. Also included are 1/2-oz packs of coarse, medium, fine and polish-grade grit, plus a necklace, ring, key-chain and double earring clips for to hold your polished stones.

No, that's not a contradiction. These are real arrowheads, made like the originals, but as replicas. You get a clear-plastic case with (4) of them, (2) made from jasper and (2) from obsidian. Sizes range from 1-3/8" long to approx 2". Has a short fact sheet, but no arrows.

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!

Earth science rocks. Start your young scientists off  with one of these rock kits from GeoCentral®. The basic rock kit has (15) examples of metamorphic, sedimentary and igneous rock; the mineral kit has (15) samples of things beyond simple rockness, such as quartz, alabaster and talc; fluorescent rock kit has (9) examples of  (7) rocks that glow, including lapis lazuli and green fluorite, plus a UV penlight. All include an 11-page booklet, magnifier and a streak plate.

Budding lapidarians will lap up this rock polishing kit which is so complete it even contains some rocks. The polishing tumbler has a (3 lb. /1 qt.) fifteen sided rubber barrel and is driven by a 115 VAC motor. Overall dimensions are 6" x 6" x 7-1/2" high. In addition to the tumbler, the kit includes an assortment of jewelry findings, a #300 4-Step Grit Pack and a detailed manual giving you easy to follow instructions. But don't think of it only as useful for jewelry making. As a hobby, our Uncle George for many years collected and polished a wide variety of rocks which he found interesting and made beautiful in and of themselves. The #300 4-Step Grit Pack is also available separately, for when your grit has run low, and includes 4oz. coarse, 4oz fine, 2oz. prepolish and 2oz polish grits. 

Turn rocks into jewelry, a few pieces at a time. Our small Rock Tumbler Geology Kit (1lb capacity) plugs into the wall and rolls those rocks around until they're all shiny and beautiful. Includes coarse and fine grinding powders, fine and finer polishing powders, 4 oz of practice gemstone rocks, a geology poster, glue, and mounting hardware to make a keychain, adjustable rings, earrings and other items. Can be set to turn from (1) to (7) days (rocks are hard, which is why they're called rocks). Measures approx 9" x 11" x 6" high overall, including the plastic dome to reduce the sound of the operation. For 10-year-olds and up.

Much better than a box of rocks, because fossils are more fun. You get (10): a trilobite, nautiloid, goniatid, petrified wood, coral, ammonite, dinosaur bone, sea urchin, shark tooth and a brachiopod, all in a handy storage case. Also comes with a fact sheet explaining what the mysterious ones were when they were alive. Also a free little fossil-inspection magnifier.
