Lovely to look at, delightful to make jewelry out of. Our (25) piece set of polished gemstones includes: amethyst; howlite; tiger eye; hematite; amazonite; carnelian; sodalite; turqurenite; plain and rose quartz; rhodonite; unakite; snowflake obsidian; orange calcite; lemon jade; four varieties of jasper (serpentine; red, brecciated, picture and blue dalmation); and more. All approx 5/8" across.
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.
Actually, it's a set of (36) different little polished gemstones and minerals from around the world, all identical sizes (1/2" x 3/8" x 1/8" thick), mounted and identified by name and origin on an 8" x 10" card. Super nice at a super price, for teachers, designers or jewelry makers. The set includes amazonite, amethyst, aventurine, black obsidian, blue lace agate, buttermilk jasper, carnelian, Dalmatian dacite, dumortierite, fancy jasper, fluorite, gold stone, hematite, howlite, jadeite, lapis, leopard skin jasper, mahogany,obsidian, moss agate, nephrite, Picasso jasper, orange calcite, picture jasper, rainbow jasper, rose quartz, rhodonite, rock crystal, rhyolite, red jasper, snowflake obsidian, sodalite, serpentine, tiger eye stone, turquoise and unakite.
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.
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.
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.
Gemstone points, waiting for you to cut, polish and mount, show to students, or just gaze at while you marvel at nature's wonders. Your each is (3) pretty points: (1) each of quartz, amethyst and citrine, each between 3/4" and 1-1/2" long.
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.
